Cozy Heat Floor-Space Heating
Cozy Heat carries a 10-year manufacturer’s warranty across both the MI fixed-length and self-regulating variants — backed by the same mineral-insulated fiberglass construction used in Hott-Wire, which provides exceptional resistance to moisture, mechanical damage, and temperature extremes over the life of the installation.
Yes. The MI Cozy Heat cable — at 11.5–20 watts per lineal foot — can provide sufficient heat output for total space heating in residential and commercial buildings, including cabins, homes, basements, sunrooms, commercial buildings, and industrial facilities. System design targets 5–15 watts per square foot of heated area depending on the building’s heat loss characteristics, insulation values, and climate. The Cozy Heat system is designed and specified by Heatizon’s team to meet each project’s heat loss requirements — not sized to a generic formula.
Cozy Heat systems can be controlled by a programmable thermostat for individual zone control — specifying the temperature and schedule for each heated area independently. For larger installations with multiple heating circuits, a relay or contactor panel allows a single thermostat or control device to activate multiple zones simultaneously. Zone-designed systems provide comfort and energy savings by heating specific areas only when needed.
Cozy Heat operates at line voltage — 120V, 208V, 240V, or 277V (480V/600V for MI) — supplied directly from the building’s electrical panel without a step-down transformer. This makes it well suited to commercial and industrial floor and slab heating projects where line-voltage supply is standard and transformer-based low-voltage systems are impractical for large areas.
Yes for floor and space heating — the cable must be embedded in a cementitious material such as mortar, standard concrete, or lightweight concrete. The cementitious heatsink is essential for even heat distribution across the floor surface above; without it, heat concentrates at the cable rather than spreading across the floor. For slab heating and heat loss prevention, the cable is adhered directly to the underside of the concrete slab — the slab itself acts as the thermal mass, and no separate heatsink embed is required.
Yes. The self-regulating variant can be used for slab heating applications — adhered to the underside of the concrete slab using aluminum tape and fasteners, as with the MI variant. The SR variant’s self-regulating characteristics mean it will reduce output as the slab reaches temperature, providing built-in energy efficiency without requiring a separate thermostat to manage overheating. For higher heat loss requirements where maximum output is needed consistently, the MI variant is the recommended choice.
Choose the self-regulating Cozy Heat cable for smaller or irregularly shaped floor areas, retrofit projects where the exact cable layout is finalized on site, and applications in milder climates or well-insulated buildings where the lower maximum output of a self-regulating cable is sufficient. The SR variant produces 5,9, or 12 watts per lineal foot and adjusts its output automatically based on surrounding temperature — it cannot overheat and is tolerant of irregular spacing during installation.
Cold leads are the non-heating sections of cable that connect the heating element to the electrical panel. Standard MI cables require cold leads to be spliced on-site — adding labor time and introducing a potential failure point at the splice. Cozy Heat’s MI cable ships with cold leads already connected at both ends from the factory. The installer routes the cold leads from the heating zone to the panel and terminates them — no specialized splicing tools or additional field connections required.
For slab heating and heat loss prevention, the MI Cozy Heat cable is adhered to the underside of a concrete slab using aluminum tape and fasteners — not embedded in the slab itself. This configuration allows the cable to heat the slab from below, preventing heat loss through the concrete and maintaining the temperature of the space above. This installation method is used when access to the underside of an existing slab is available and embedding in a new pour is not feasible or required.
For floor and space heating, the MI Cozy Heat cable is embedded in a cementitious material — mortar, standard concrete, or lightweight concrete — beneath the finished floor surface. The cable is laid at the spacing specified in the system design, and the cementitious layer is applied over the top before the floor covering is installed. The heatsink provided by the cementitious embed distributes heat evenly across the floor surface above.
Choose the MI fixed-length Cozy Heat cable for large commercial and industrial floor heating projects, slab heating applications, and any installation where maximum watt output and long-term durability are the priority. The MI variant produces 11.5–20 watts per lineal foot — the higher end of the range needed for total space heating and demanding heat loss prevention applications. Because it is a fixed-length product, the cable length must be specified and ordered based on the system design before installation begins.
Yes. Cozy Heat is ETL listed — the same listing that covers Heatizon’s Hott-Wire cable, reflecting their identical cable construction. ETL listing is issued by Intertek, an OSHA-recognized Nationally Recognized Testing Laboratory carrying equal legal standing to UL and CSA listings in the United States.
Cozy Heat serves two distinct applications, each with a different installation method. The first is floor and space heating — where the cable is embedded in a cementitious material such as mortar, concrete, or lightweight concrete beneath the floor covering, warming the floor surface and the room above. The second is slab heating and heat loss prevention — where the cable is adhered to the underside of an existing concrete slab using aluminum tape and fasteners, preventing heat loss through the slab and maintaining the temperature of the space above. The installation method, cable spacing, and watt output target differ significantly between the two applications.
Cozy Heat and Hott-Wire share the same fundamental cable construction — both are mineral-insulated line-voltage cables with fiberglass insulation, a copper outer tube, HDPE jacket, and factory pre-connected cold leads on the MI variant. The difference is application: Hott-Wire is designed and rated for outdoor snow melting in concrete, asphalt, and pavers. Cozy Heat is designed for interior floor warming, space heating, and slab heating applications. Both are ETL listed and available in MI fixed-length and self-regulating cut-to-length variants.
Cozy Heat is Heatizon’s line-voltage electric radiant heating cable for interior floor warming, space heating, and slab heating — available in two configurations. The MI (mineral-insulated) fixed-length variant uses a central copper conductor surrounded by fiberglass insulation compressed inside a copper outer tube with an HDPE jacket, factory-terminated with pre-connected cold leads at both ends. The self-regulating cut-to-length variant automatically adjusts its heat output based on ambient temperature and is cut to length on site. Both variants are ETL listed and operate at line voltage — no step-down transformer required.
Custom Panels
Every Heatizon custom panel includes complete wiring diagrams and full end-user support. The panel is engineered to the project specifications, assembled in Heatizon’s UL 508A certified facility, and shipped ready for installation. Project-specific indicators, switches, and controllers are integrated as required.
Yes. In addition to custom-built panels, Heatizon offers a complete line of standard off-the-shelf panels with GFEP protection, indicators, and support for all voltages across a range of breaker sizes — available for immediate shipment. Standard panels are appropriate for straightforward installations where project-specific customization is not required.
Heatizon custom panels can integrate with a wide range of activation devices — including automatic snow and ice detection sensors, temperature sensors, moisture sensors, programmable thermostats, and manual overrides. Panels can be configured with a single activator controlling multiple circuits for uniformity, or with independently zoned activators for each circuit for maximum flexibility.
Yes. Heatizon custom panels can be configured to relay signals to Building Management Systems (BMS) and Building Automation Systems (BAS), enabling the radiant heating system to integrate with the building’s central control infrastructure. Current monitoring, fault signals, and activation status can all be relayed to the BMS/BAS depending on the project requirements.
All types of enclosures are available — including NEMA-rated stainless steel and standard enclosures — sized and specified to the project’s environment and installation location. Indoor, outdoor, wet location, and hazardous location enclosures can all be accommodated depending on the project requirements.
Heatizon custom panels are available for 120V, 208V, 240V, 277V, and 480V supply voltages — covering the full range of commercial and industrial electrical supply configurations. Panel breaker sizing is specified to the project’s circuit loads.
Heatizon’s Custom Panel Builds service designs and manufactures control panels for radiant heating systems to project-specific requirements. As a UL 508A certified panel shop, Heatizon engineers custom panels that integrate breakers, activation devices, monitoring functions, and BMS/BAS outputs — configured to the specific voltage, circuit count, enclosure type, and control requirements of each project. Every custom panel ships with complete wiring diagrams and is backed by full end-user support.
UL 508A is the standard for Industrial Control Panels — the governing certification for control panel enclosures that integrate components such as breakers, relays, indicators, and controllers into a listed panel assembly. A UL 508A certified panel shop is licensed to engineer, assemble, and list custom control panels to this standard. For commercial and industrial projects requiring a listed panel assembly — as required by most local building codes and electrical inspections — a UL 508A panel shop is a prerequisite for the work. Heatizon is a UL 508A certified panel shop, one of very few radiant heating manufacturers with this certification.
Deck Snow Melting Systems
Small aluminum joist plates are included to protect the joists where the Hott-Wire cable crosses over them during installation. Because Hott-Wire is a line-voltage cable, direct contact with the wood joist at crossing points needs to be avoided — the joist plates sit between the cable and the joist surface at those points, protecting the wood and maintaining a safe installation. They are part of the complete system package.
Decks over a heated living space or roof present a secondary concern — meltwater from the deck can run down onto the roof beneath and refreeze, forming ice dams at the roof edge. Installing a roof deicing system on the roof below the deck — ZMesh for non-metal roofing or Tuff Cable in Invizimelt for metal roofing — ensures meltwater has a complete path off the building without backing up under the roof edge.
For decks adjacent to gutters or downspouts, pairing the deck pan system with GutterMelt keeps the full drainage path clear — meltwater from the heated deck needs to flow freely through gutters and downspouts to the ground. GutterMelt is recommended wherever deck meltwater drains into a gutter system.
Yes, There are a few secondary options are available for specific deck constructions. For decks with a concrete or mortar substrate — where embedding cable is feasible — Tuff Cable can be embedded directly in the substrate for even heat distribution. For decks with non-conductive wood or composite decking on traditional framing where no heatsink or pan system can be fitted, ZMesh or Invizimelt can be laid on a solid sub-deck beneath the decking. Both are secondary solutions; the deck pan system with Hott-Wire is Heatizon’s recommended and most complete deck deicing approach for wood-framed joist construction.
Yes. The deck pan system — pans, Hott-Wire cable, relay panel, and activator — contains no moving parts. No moving parts means no wear components, no scheduled mechanical maintenance, and no service requirements beyond verifying activation at the start of each winter season.
The system activates automatically via a snow and ice detection sensor that triggers heating when temperature drops below threshold and moisture is present — no manual switching required. A relay panel allows a single activation device to control multiple heating circuits across larger deck surfaces simultaneously.
The deck pan heating system supports 120V, 208V, 240V, and 277V supply voltages — compatible with most residential and commercial electrical configurations without requiring a transformer. Voltage is specified at the time of system design based on the project’s electrical supply.
Heavy-duty aluminum tape is applied over the Hott-Wire cable after it is routed into the pan channels. Aluminum’s high thermal conductivity spreads heat rapidly and evenly across the full pan surface, directing it upward through the deck surface above. Without the tape, heat would concentrate at the cable rather than distributing across the pan, reducing melting efficiency significantly. The aluminum tape is what makes the pan system an effective heatsink in addition to a simple cable holder.
The deck pan system uses Hott-Wire MI (mineral-insulated) fixed-length cable — a central copper conductor surrounded by fiberglass insulation inside a copper outer tube and HDPE jacket, with cold leads factory pre-connected at both ends. The MI variant’s construction withstands the mechanical loads of deck installation and delivers consistent, reliable heat output over the life of the installation. Factory pre-connected cold leads eliminate field splicing during installation.
Every Heatizon deck pan heating system includes Hott-Wire heating cable, insulated aluminum heating pans, joist plates, heavy-duty aluminum tape, a relay panel, and an automatic snow and ice detection activator. Each system is custom-configured to the project’s dimensions, joist spacing, voltage, and decking material.
Aluminum insulated heating pans are placed over two joist gaps (24″ or 32″), notches are made to install joist protection plates where the heating cable crosses any wood. Next, Hott-Wire MI line-voltage cable is then routed through the pan channels and covered with heavy-duty aluminum tape, which spreads heat rapidly and evenly across the full pan surface and directs it upward into the deck surface above. The deck face is installed on top — screws or nails can pass through the aluminum pan or between adjacent pans to secure the decking to the joists below.
Yes. For new deck construction, the system is installed after all joists are in place and before the deck surface is added — the pans are positioned on the joists, Hott-Wire is routed through the channels, and the deck face is then installed over the top. For existing decks, the deck surface must be removed to expose the joists, the pan system installed, and the deck surface reinstalled. Both 12-inch and 16-inch joist spacing are compatible.
The deck pan heating system is designed for wood-framed decks with joists spaced either 12 inches or 16 inches on center. The insulated aluminum pans are engineered to sit on the joists and span the gap between them, providing a continuous heated surface beneath the deck face.
Heatizon’s primary deck deicing solution is the deck pan heating system — a patented, complete assembly using insulated aluminum heating pans and Hott-Wire mineral-insulated line-voltage cable, engineered for wood-framed decks with standard 12-inch or 16-inch joist spacing. The pans sit on top of the joists beneath the deck surface, Hott-Wire cable is routed through the pan channels and taped in place, and the deck face is installed directly over the pans. The system is invisible in the finished deck, activates automatically, and is custom-configured for each project. For other deck constructions where the pan system is not applicable, Heatizon also offers secondary options using ZMesh or Tuff Cable — contact a distributor to confirm the right approach.
Floor & Space Heating
WarmWallz panels mount to a wall or ceiling using the included wall mount or ceiling bracket, compatible with all models. Installation does not require structural modification — the panel is mounted directly to the wall or ceiling surface and connected to the electrical supply per the model’s wattage and voltage requirements.
Outside of regular cleaning/dusting, yes. WarmWallz panels are solid-state with no moving parts, requiring no routine maintenance or servicing after installation.
WarmWallz panels can serve as either a primary heat source for a room or as supplemental heating alongside an existing system, depending on the panel wattage selected relative to the room’s heat loss. Heatizon offers WarmWallz panels in a range of sizes and power outputs to match different room sizes and heating requirements — see the size and wattage chart for available configurations.
WarmWallz panels include a wall mount or ceiling bracket compatible with all models. Optional accessories include a towel rail, available on select GS and CR wattages, and wall offset screws, available on all models except the U line. Additional accessories may be available for special installation conditions — consult a Heatizon distributor for availability.
The right WarmWallz model depends on three factors: mounting location (wall, ceiling, or both), desired finish (smooth, textured, decorative, or glass), and the heat output required for the space. WarmWallz Basic and U+ offer the most installation flexibility with both wall and ceiling mounting. WarmWallz U is ceiling-only with enhanced heat dispersion. WarmWallz CR is wall-only with a decorative finish. WarmWallz GS offers a glass surface for wall or ceiling installation. Contact a Heatizon distributor to select the right model and size for your specific space and heat loss requirements.
WarmWallz CR is a wall-mountable radiant heating panel with an elegant decorative finish and texture, designed to add radiant heating to a space while complementing the interior design. CR panels are wall mountable only.
WarmWallz GS is a radiant heating panel with a glass heating surface, suitable for both wall and ceiling mounting. The glass surface provides a clean, modern aesthetic alongside the panel’s radiant heating function, making it a common choice for bathrooms and visible living spaces where appearance matters alongside performance.
WarmWallz Basic has a smooth surface that is easy to clean and maintain, and can be mounted on either a wall or ceiling. WarmWallz U has a textured coating designed to improve heat dispersion across the panel surface, but is ceiling mountable only. The choice depends on whether wall mounting flexibility or improved heat dispersion is the priority for the installation.
Heatizon offers five WarmWallz model lines, each suited to different applications and finishes. WarmWallz (Basic) has a smooth, easy-to-clean surface and is wall or ceiling mountable. WarmWallz U has a textured coating for improved heat dispersion and is ceiling mountable only. WarmWallz U+ offers diverse sizes and coating options and is wall or ceiling mountable. WarmWallz CR provides an elegant decorative finish and texture and is wall mountable only. WarmWallz GS features a glass heating surface and is wall or ceiling mountable.
WarmWallz panels can be installed on walls or ceilings, depending on the model selected. Some models are wall or ceiling mountable, while others are designed for one mounting orientation only — see the model comparison for specific mounting compatibility. WarmWallz is suitable for residential and commercial spaces including bathrooms, offices, living spaces, and other interior rooms.
Yes. WarmWallz panels are ETL listed for sale and installation in the United States and Canada.
Radiant panel heating works by emitting infrared radiant energy that travels through the air largely unabsorbed until it strikes a solid object — a wall, piece of furniture, or floor. Approximately 85% of that radiant energy is absorbed by the object, raising its surface temperature directly. The warmed objects then radiate heat into the room and transfer some heat to the surrounding air by convection. This differs from forced-air heating, which heats air directly and relies on air circulation to warm the room.
WarmWallz is Heatizon’s line of premium electric radiant heating panels for walls and ceilings. The panels transfer heat primarily through radiant energy — approximately 85% of the radiant energy emitted is absorbed by surrounding objects (walls, furniture, floors), warming them directly, while the remaining heat transfers to the surrounding air by convection. This provides efficient, even heating without the air movement and temperature stratification of forced-air systems. WarmWallz is ETL listed for sale and installation in the United States and Canada.
Floorizwarm is available through Moreheat.com, Radiantshop.com and through Heatizon’s network of distributors.
Yes. Floorizwarm is highly customizable to the layout of the space — cable spacing can be adjusted to maximize heat output in areas where it’s needed most and minimize or eliminate heating in areas where it isn’t, such as under cabinetry or fixtures. This allows the kit to be configured precisely to the room’s actual layout rather than applying uniform heating across the entire floor area.
Yes. Floorizwarm’s Tuff Cable heating element is embedded in a mortar bed beneath the finished floor surface — the mortar acts as the heatsink, distributing heat evenly across the floor area above. This is the same installation method used for standard Tuff Cable floor heating installations.
Floorizwarm is compatible with tile, stone, slate, hardwood, laminate, engineered flooring, linoleum, vinyl, and carpet — installed wherever a mortar bed is used beneath the floor covering. It is also suitable for shower floors and other wet area applications.
Floorizwarm systems are designed to produce 7.5 to 15 watts per square foot. The lower end of this range is typically specified for comfort floor warming in well-insulated spaces, while the higher end is used where Floorizwarm needs to serve as a more significant heat source for the room — such as a small bathroom or laundry room with greater heat loss. Heatizon configures the wattage for each kit based on the specific room and application.
Floorizwarm carries a 25-year manufacturer warranty — the same warranty length as Tuff Cable, reflecting the fact that Floorizwarm uses the identical Tuff Cable heating element at its core.
Floorizwarm and standard Tuff Cable floor heating use the identical heating element — the difference is packaging and scale. Floorizwarm is a complete, pre-sized kit specifically configured for smaller areas, sold as a single package at a lower price point than ordering Tuff Cable separately for a custom large-area installation. For floor areas larger than a typical kitchen, bathroom, or entryway, a custom-designed Tuff Cable system is the more cost-effective option.
Floorizwarm is Heatizon’s complete, low-voltage radiant floor heating kit designed specifically for smaller and wet areas — kitchens, bathrooms, laundry rooms, entryways, and showers. It uses Tuff Cable, the same low-voltage coated copper heating element used across Heatizon’s larger snow melting and floor heating systems, embedded in a mortar bed beneath the finished floor. Floorizwarm is sold as a complete package — everything needed for the specified area is included.
Cozy Heat carries a 10-year manufacturer’s warranty across both the MI fixed-length and self-regulating variants — backed by the same mineral-insulated fiberglass construction used in Hott-Wire, which provides exceptional resistance to moisture, mechanical damage, and temperature extremes over the life of the installation.
Yes. The MI Cozy Heat cable — at 11.5–20 watts per lineal foot — can provide sufficient heat output for total space heating in residential and commercial buildings, including cabins, homes, basements, sunrooms, commercial buildings, and industrial facilities. System design targets 5–15 watts per square foot of heated area depending on the building’s heat loss characteristics, insulation values, and climate. The Cozy Heat system is designed and specified by Heatizon’s team to meet each project’s heat loss requirements — not sized to a generic formula.
Cozy Heat systems can be controlled by a programmable thermostat for individual zone control — specifying the temperature and schedule for each heated area independently. For larger installations with multiple heating circuits, a relay or contactor panel allows a single thermostat or control device to activate multiple zones simultaneously. Zone-designed systems provide comfort and energy savings by heating specific areas only when needed.
Cozy Heat operates at line voltage — 120V, 208V, 240V, or 277V (480V/600V for MI) — supplied directly from the building’s electrical panel without a step-down transformer. This makes it well suited to commercial and industrial floor and slab heating projects where line-voltage supply is standard and transformer-based low-voltage systems are impractical for large areas.
Yes for floor and space heating — the cable must be embedded in a cementitious material such as mortar, standard concrete, or lightweight concrete. The cementitious heatsink is essential for even heat distribution across the floor surface above; without it, heat concentrates at the cable rather than spreading across the floor. For slab heating and heat loss prevention, the cable is adhered directly to the underside of the concrete slab — the slab itself acts as the thermal mass, and no separate heatsink embed is required.
Yes. The self-regulating variant can be used for slab heating applications — adhered to the underside of the concrete slab using aluminum tape and fasteners, as with the MI variant. The SR variant’s self-regulating characteristics mean it will reduce output as the slab reaches temperature, providing built-in energy efficiency without requiring a separate thermostat to manage overheating. For higher heat loss requirements where maximum output is needed consistently, the MI variant is the recommended choice.
Choose the self-regulating Cozy Heat cable for smaller or irregularly shaped floor areas, retrofit projects where the exact cable layout is finalized on site, and applications in milder climates or well-insulated buildings where the lower maximum output of a self-regulating cable is sufficient. The SR variant produces 5,9, or 12 watts per lineal foot and adjusts its output automatically based on surrounding temperature — it cannot overheat and is tolerant of irregular spacing during installation.
Cold leads are the non-heating sections of cable that connect the heating element to the electrical panel. Standard MI cables require cold leads to be spliced on-site — adding labor time and introducing a potential failure point at the splice. Cozy Heat’s MI cable ships with cold leads already connected at both ends from the factory. The installer routes the cold leads from the heating zone to the panel and terminates them — no specialized splicing tools or additional field connections required.
For slab heating and heat loss prevention, the MI Cozy Heat cable is adhered to the underside of a concrete slab using aluminum tape and fasteners — not embedded in the slab itself. This configuration allows the cable to heat the slab from below, preventing heat loss through the concrete and maintaining the temperature of the space above. This installation method is used when access to the underside of an existing slab is available and embedding in a new pour is not feasible or required.
For floor and space heating, the MI Cozy Heat cable is embedded in a cementitious material — mortar, standard concrete, or lightweight concrete — beneath the finished floor surface. The cable is laid at the spacing specified in the system design, and the cementitious layer is applied over the top before the floor covering is installed. The heatsink provided by the cementitious embed distributes heat evenly across the floor surface above.
Choose the MI fixed-length Cozy Heat cable for large commercial and industrial floor heating projects, slab heating applications, and any installation where maximum watt output and long-term durability are the priority. The MI variant produces 11.5–20 watts per lineal foot — the higher end of the range needed for total space heating and demanding heat loss prevention applications. Because it is a fixed-length product, the cable length must be specified and ordered based on the system design before installation begins.
Yes. Cozy Heat is ETL listed — the same listing that covers Heatizon’s Hott-Wire cable, reflecting their identical cable construction. ETL listing is issued by Intertek, an OSHA-recognized Nationally Recognized Testing Laboratory carrying equal legal standing to UL and CSA listings in the United States.
Cozy Heat serves two distinct applications, each with a different installation method. The first is floor and space heating — where the cable is embedded in a cementitious material such as mortar, concrete, or lightweight concrete beneath the floor covering, warming the floor surface and the room above. The second is slab heating and heat loss prevention — where the cable is adhered to the underside of an existing concrete slab using aluminum tape and fasteners, preventing heat loss through the slab and maintaining the temperature of the space above. The installation method, cable spacing, and watt output target differ significantly between the two applications.
Cozy Heat and Hott-Wire share the same fundamental cable construction — both are mineral-insulated line-voltage cables with fiberglass insulation, a copper outer tube, HDPE jacket, and factory pre-connected cold leads on the MI variant. The difference is application: Hott-Wire is designed and rated for outdoor snow melting in concrete, asphalt, and pavers. Cozy Heat is designed for interior floor warming, space heating, and slab heating applications. Both are ETL listed and available in MI fixed-length and self-regulating cut-to-length variants.
Cozy Heat is Heatizon’s line-voltage electric radiant heating cable for interior floor warming, space heating, and slab heating — available in two configurations. The MI (mineral-insulated) fixed-length variant uses a central copper conductor surrounded by fiberglass insulation compressed inside a copper outer tube with an HDPE jacket, factory-terminated with pre-connected cold leads at both ends. The self-regulating cut-to-length variant automatically adjusts its heat output based on ambient temperature and is cut to length on site. Both variants are ETL listed and operate at line voltage — no step-down transformer required.
Yes — unlike ZMesh, Tuff Cable must always be embedded in a heatsink material. For floor heating, this is typically a mortar bed, concrete slab, or self-leveling cementitious compound. The heatsink stores and distributes the heat from the cable evenly across the floor surface. This requirement adds some installation complexity compared to mesh-based systems, but results in excellent, even heat distribution and long cable life due to the protection the embed provides.
Yes. Tuff Cable floor systems can be designed for both supplemental floor warming — where the primary heat source is a furnace or boiler — and total space heating, where the radiant floor system provides all the heat for the space. Total space heating applications require higher wattage and closer run spacing than floor warming. Heatizon’s design team determines the correct configuration based on room dimensions, insulation levels, heat loss calculations (provided by the project’s engineer), and climate data.
Tuff Cable is compatible with almost all floor coverings where a heatsink material is present in the floor assembly — including hardwood, carpet, tile, laminate, engineered wood, linoleum, and vinyl. The heatsink is typically concrete, a mortar bed, or a self-leveling compound into which the Tuff Cable is embedded before the floor covering is installed. Unlike ZMesh, Tuff Cable requires this heatsink layer — it cannot be installed directly under flooring without an embed.
Yes. Tuff Cable is listed by Intertek (ETL) — an OSHA-recognized Nationally Recognized Testing Laboratory — to UL and CSA standards for snow and ice melting on surfaces and roofs, and for interior floor heating applications. Together with ZMesh, Tuff Cable is one of only two products in the world authorized under UL Standard 1588 for snow and ice melting installed under roofing materials. All Heatizon systems are designed to ASHRAE standards for heating load calculation and energy efficiency.
Tuff Cable and ZMesh are both Heatizon low-voltage heating elements and both are ETL listed under UL Standard 1588 for under-roof snow melting — but they are designed for different installation methods. Tuff Cable is a round copper cable that must always be embedded in a heatsink material (concrete, asphalt, mortar, Invizimelt panel). ZMesh is a flat bronze mesh that lays directly beneath flooring or roofing without any embed. Tuff Cable is the right choice where a heatsink is present or required — driveways, metal roofs, floor overlays. ZMesh is the right choice where no embed is possible or desired — under non-metal shingles, hardwood floors, and carpet.
Tuff Cable carries an industry-leading 25-year manufacturer’s warranty — the longest available for any electric radiant heating cable in its category. The warranty reflects the cable’s construction: 10-gauge coated copper heating cable that gets embedded in a protective heatsink, with footage marks for verifiable installation, and a low-voltage design that reduces electrical stress on the insulation over time. Heatizon has documented installations from decades ago that remain fully operational.
Tuff Cable is a low-voltage system powered by a step-down transformer that reduces the supply voltage — typically 120V, 208V, 240V, or 277V AC — to 65 volts or less at the cable. This low operating voltage is one of Tuff Cable’s key safety advantages over line-voltage systems, and it also allows the cable to be cut and spliced in the field, and to be installed in surfaces where line-voltage systems are not permitted or practical.
Tuff Cable is a low-voltage electric radiant heating cable made from a specially-engineered copper heating wire (approximately 10-gauge), manufactured by Heatizon Systems. It is chemical and gasoline resistant, comes with footage marks printed along the cable for easy layout verification, and is designed to always be embedded in a heatsink material — such as concrete, asphalt, mortar, stone, pavers, or Heatizon’s Invizimelt Panel. Tuff Cable is a cut-to-length product, giving installers precise control over system sizing without material waste.
ZMesh is a cut-to-length product, unlike most UL-listed radiant heating cables which are fixed-length. This gives installers flexibility to size each run precisely to the space — eliminating the waste and design constraints of fixed-length systems. ZMesh is available in rolls from 50 to 400 feet and can be cut on site to the exact length required by the project layout.
Yes. ZMesh is one of the only radiant heating elements on the market that can be repaired in the field if cut or damaged. Repair requires a customized copper splice plate and solder — a straightforward process compared to the full element replacement required by most competing fixed-length heating cables. This repairability is a meaningful long-term advantage, particularly for installations that may be subject to renovation or remodeling work years after the original installation.
Yes — provided the nail, screw, or staple does not make contact with any other electrically conductive material. ZMesh can be nailed and stapled through freely during roofing and flooring installation, which is one of its key practical advantages over conventional heating cables. This eliminates the need to plan fastener locations around the heating element and allows standard roofing and flooring installation techniques to proceed unmodified.
Yes. ZMesh can be retrofitted between floor joists from an unfinished basement or crawlspace below, without disturbing the finished floor above. This makes it one of the only radiant heating elements that can be added to an existing home without any flooring removal — a significant advantage for renovation projects where disruption and cost need to be minimized.
Yes. ZMesh is well suited to hardwood floor heating. The 12-inch width is the standard recommendation for hardwood applications. Before installation, allow the hardwood to acclimate to the room’s humidity level for several weeks to minimize dimensional changes after heating begins. After laying and connecting ZMesh, test and then run the system for before nailing or stapling the hardwood to the subfloor — this allows the wood to adjust to its heated operating temperature. As with all radiant floor heating under hardwood, confirm with the flooring manufacturer that surface temperatures will not exceed 85°F.
No. Unlike most radiant heating cables that must be embedded in a mortar or self-leveling compound to transfer heat, ZMesh is installed directly beneath the floor covering without any mortar bed or heatsink embedment. Because ZMesh is only 1/16 inch thick, it adds virtually no height to the floor assembly — eliminating the cost of a cementitious mud bed, the structural upgrades needed to support its weight, and the installation complexity it introduces. This makes ZMesh one of the most practical radiant floor heating solutions for both new construction and retrofit projects.
ZMesh carries an industry-leading 25-year manufacturer’s warranty. The long warranty is backed by the product’s construction: because ZMesh is installed under roofing or flooring rather than exposed to the elements, it is protected from UV damage, physical impact, and weathering. Heatizon’s distributors have documented ZMesh installations from decades ago that remain fully operational and visually unchanged. In most installations, ZMesh will outlast the roofing or flooring material installed above it.
The width choice affects heat output, not coverage area. The 9-inch mesh allows more runs to be placed in a given space, resulting in higher watts per square foot — up to 13 watts per square foot — making it the recommended choice for roof deicing where aggressive snow and ice melting is needed. The 12-inch mesh produces a lower watt density, which is better suited for radiant floor heating where even, gentle warmth is the goal. Heatizon’s design team specifies the appropriate width for each project based on application and local climate.
ZMesh serves two distinct applications: under-shingle roof deicing and ice dam prevention, and radiant floor and space heating. For roof applications, ZMesh is installed beneath non-conductive shingles, membranes, and wood decking to melt snow and ice from eaves and valleys. For floor applications, ZMesh is installed beneath virtually any non-conductive floor covering — including hardwood, tile, stone, carpet, engineered wood, linoleum, and vinyl — to provide even, comfortable radiant warmth. Both applications use the same physical element; the installation method and wattage configuration differ by use case.
ZMesh is a woven bright bronze metal mesh heating element manufactured by Heatizon Systems. It resembles screen door material in appearance and is approximately 1/16 inch thick, available in 9-inch and 12-inch widths and in lengths from 50 to 400 feet. The bronze construction is highly durable, fully recyclable, and designed to outlast the roofing or flooring installed above it. ZMesh has been in continuous production and use since 1979.
ZMesh comes with an industry leading, 25-year manufacturer’s warranty.
Since 1979, Tuff Cable systems have been sold worldwide and are still in operation, worry free.
Tuff Cable comes with an industry leading, 25-year manufacturer’s warranty.
Tuff Cable is ETL Listed for snow and ice melting on surfaces and roofs and for interior floor heating applications.
Floorizwarm Floor-Space Heating
Floorizwarm is available through Moreheat.com, Radiantshop.com and through Heatizon’s network of distributors.
Yes. Floorizwarm is highly customizable to the layout of the space — cable spacing can be adjusted to maximize heat output in areas where it’s needed most and minimize or eliminate heating in areas where it isn’t, such as under cabinetry or fixtures. This allows the kit to be configured precisely to the room’s actual layout rather than applying uniform heating across the entire floor area.
Yes. Floorizwarm’s Tuff Cable heating element is embedded in a mortar bed beneath the finished floor surface — the mortar acts as the heatsink, distributing heat evenly across the floor area above. This is the same installation method used for standard Tuff Cable floor heating installations.
Floorizwarm is compatible with tile, stone, slate, hardwood, laminate, engineered flooring, linoleum, vinyl, and carpet — installed wherever a mortar bed is used beneath the floor covering. It is also suitable for shower floors and other wet area applications.
Floorizwarm systems are designed to produce 7.5 to 15 watts per square foot. The lower end of this range is typically specified for comfort floor warming in well-insulated spaces, while the higher end is used where Floorizwarm needs to serve as a more significant heat source for the room — such as a small bathroom or laundry room with greater heat loss. Heatizon configures the wattage for each kit based on the specific room and application.
Floorizwarm carries a 25-year manufacturer warranty — the same warranty length as Tuff Cable, reflecting the fact that Floorizwarm uses the identical Tuff Cable heating element at its core.
Floorizwarm and standard Tuff Cable floor heating use the identical heating element — the difference is packaging and scale. Floorizwarm is a complete, pre-sized kit specifically configured for smaller areas, sold as a single package at a lower price point than ordering Tuff Cable separately for a custom large-area installation. For floor areas larger than a typical kitchen, bathroom, or entryway, a custom-designed Tuff Cable system is the more cost-effective option.
Floorizwarm is Heatizon’s complete, low-voltage radiant floor heating kit designed specifically for smaller and wet areas — kitchens, bathrooms, laundry rooms, entryways, and showers. It uses Tuff Cable, the same low-voltage coated copper heating element used across Heatizon’s larger snow melting and floor heating systems, embedded in a mortar bed beneath the finished floor. Floorizwarm is sold as a complete package — everything needed for the specified area is included.
General Heatizon Product Questions
All of our systems come with complete installation manuals and can be installed by any electrician, contractor, or experienced “do-it-yourselfer.” An electrician is needed to supply the necessary power and to Control Unit location. We also offer installation DVD clips for an installation reference. Heatizon offers unlimited technical support to customers.
Yes they sure can, this would fall under our under roof deicing system, or in snow melting look under deck and using a Invizimelt system with Tuff Cable.
Yes you can resurface a retrofit. There are products that can resurface concrete using epoxies or polymers. It can be thin or thick depending on which product is chosen.
Line voltage products like Heatizon lines of MI Cables, Heatwave floor warming mats, and Self Regulating Cables are fed by a typical 120V, 208V, 240V, 277V, 480V and in some cases for MI Cables up to 600V AC power. These products are either constant wattage single conductor or dual conductor or dual conductor self regulating. High voltage products do not require a transformer and are an economical solution for many projects. Typical high voltage products offer a lower warranty than low voltage products and more expensive circuit breaker components for outdoor applications than low voltage systems. Low voltage products use a step down transformer to convert high voltage to low voltage. These systems are very easy to repair compared to high voltage products while using a safe low voltage power source. Low voltage systems offer a higher warranty than their line voltage counterparts. Heatizon offers such a wide range of product choices because each and every one has an application where they fit best offering our customers a choice for the best product to fit their budget and application.
Guttermelt Roof & Gutter Deicing
For decks adjacent to gutters or downspouts, pairing the deck pan system with GutterMelt keeps the full drainage path clear — meltwater from the heated deck needs to flow freely through gutters and downspouts to the ground. GutterMelt is recommended wherever deck meltwater drains into a gutter system.
A GutterMelt kit includes the heating cable with a factory-attached 6-foot power cord and LED plug, downspout brackets, roof clips, a complete installation and instruction manual, and access to Heatizon’s technical support team.
Yes. GutterMelt cable and kits can be installed in existing gutters and downspouts without modification to the gutter system itself. The cable is secured using hangers and clips designed for the installation, making it a straightforward retrofit for homes and buildings experiencing ice dam or gutter freezing problems.
GutterMelt is recommended for use in conjunction with a roof deicing system such as ZMesh or Tuff Cable in Invizimelt. GutterMelt protects gutters and downspouts, but meltwater coming off a roof still needs somewhere to go — pairing GutterMelt with an under-roof or surface deicing system ensures water has a clear path off the building rather than just clearing the gutters in isolation.
GutterMelt can be thermostatically controlled, hard-wired, or sensor-controlled, depending on the installation. For larger commercial projects, Heatizon offers a variety of relay panels that allow multiple circuits to be controlled from a single activation device. Automatic sensors that detect moisture and temperature are the recommended activation method for energy efficiency — the system only runs when conditions require it.
GutterMelt kits include downspout hangers and roof clips for straightforward installation in gutters, downspouts, and along roof eaves. Bulk GutterMelt cable is installed by a contractor or electrician according to a project-specific layout, typically run in a zigzag pattern along the eave and straight down through downspouts and drains. Cable can be cut to length in the field for custom runs.
GutterMelt’s cable construction is engineered to prevent water wicking along the length of the cable — a common failure point in lower-quality heat trace cables where water travels along the cable jacket and causes internal damage or shorting over time. This construction detail contributes directly to GutterMelt’s industry-leading warranty length.
Pre-configured GutterMelt kits are available in standard lengths of 10, 30, 50, 70, 90, 110, and 130 linear feet. GutterMelt sold by the foot can be cut to any length required for the project, giving installers flexibility for non-standard gutter and downspout configurations.
GutterMelt is available in 120V, 208V, 240V, and 277V configurations. Pre-configured kits are sold in 120V with a factory-attached plug; bulk cable sold by the foot is available across the full voltage range for custom commercial and residential installations.
GutterMelt SR cable produces 5, 9, 12, or up to 24 watts (CW version only) per linear foot at 32°F in snow and ice conditions, depending on the wattage rating selected for the project. Heatizon’s design team specifies the correct wattage based on climate, gutter/downspout size, and the specific freeze protection requirements of the installation.
Constant Wattage GutterMelt produces a fixed heat output regardless of ambient temperature, unlike the self-adjusting SR version. It’s typically specified for longer cable runs or larger commercial systems where consistent, predictable wattage across the entire length is required for accurate system design. Both SR and CW versions are listed to UL and CSA standards and carry Heatizon’s standard warranties based on per-foot vs. kit purchase.
Yes. GutterMelt SR cable is safe for use with plastic downspouts because of its self-regulating heating characteristics — the cable cannot overheat, since its heat output decreases as the surrounding temperature rises. This makes it safe on materials that would be damaged by a constant-output cable running too hot in warmer conditions.
Yes. GutterMelt is ETL listed for the United States and Canada, certified to UL and CSA standards.
GutterMelt cable sold per foot carries a 10-year manufacturer’s warranty. Pre-configured cordset kits carry a 5-year warranty. The difference comes from the kit’s added components — the factory termination and LED plug — which have a shorter rated service life than the heating cable itself. The cable in both versions is identical; the warranty difference reflects the additional hardware required to make the kit plug-and-play.
GutterMelt sold per foot is bulk cable cut to the length specified for the project, intended for custom installation by a contractor or electrician. GutterMelt kits are pre-configured, ready-to-install cordsets that come factory-terminated with a 6-foot power cord and LED plug, along with downspout hangers and roof clips, in standard lengths from 10 to 130 linear feet. The kit format trades custom sizing for plug-and-play simplicity — ideal for straightforward residential installations.
GutterMelt is Heatizon’s heat trace cable for gutters, downspouts, eaves, and drains — designed to maintain a clear water flow path and prevent ice dam formation. It’s available in Self-Regulating (SR) and is ETL listed to UL and CSA standards for the United States and Canada. GutterMelt operates at 120V, 208V, 240V, or 277V and can be ordered by the foot for custom installations or as a pre-configured, ready-to-install cordset kit.
Heat Trace-Pipe Freeze Protection
Yes. Installing pipe insulation over Outpipe cable significantly reduces the energy required to maintain the pipe temperature — the insulation limits heat loss from the pipe surface to the surrounding air, allowing the cable to work more efficiently. Without insulation, the cable must work harder to compensate for continuous heat loss, increasing energy consumption. The type and thickness of insulation depends on pipe diameter, ambient temperature, and the desired maintenance temperature.
Yes. Outpipe is rated for outdoor installation — protecting exposed exterior pipes, outdoor valve stations, and unheated structures such as barns, garages, and outbuildings where pipes are at risk of freezing. The ETL listing covers outdoor applications.
Outpipe cable is wrapped or run longitudinally along the pipe surface and secured with fiberglass tape at regular intervals. For freeze protection only, a single cable run along the bottom of the pipe is typically sufficient. For temperature maintenance at higher heat loss rates, a spiral wrap or multiple longitudinal runs increase watt density per linear foot of pipe. The pipe is then insulated over the cable to minimize heat loss and reduce energy consumption. Bulk cable is connected to the electrical supply by a licensed electrician; kit versions plug into a GFCI-protected 120V outlet.
Outpipe is used for four primary pipe heating applications. Pipe freeze protection maintains water and fluid lines above freezing point during cold weather. Pipe temperature maintenance keeps process fluids at a specific operating temperature regardless of ambient conditions. Valve freeze protection keeps valves and actuators operable in cold environments where ice can prevent valve movement. Tank heating maintains the temperature of storage tanks holding fluids that would freeze, thicken, or degrade below a minimum temperature.
The difference is the added kit hardware — the factory termination and plug — which have a shorter rated service life than the heating cable itself. The SR cable inside the kit is identical to the bulk SR cable with the 10-year warranty. For permanent installations where long-term performance is the priority, bulk cable terminated by a licensed electrician carries the full 10-year warranty. For plug-and-play residential applications where convenience is the priority, the kit format offers a practical, ready-to-install solution at the 5-year warranty tier.
Each Outpipe kit includes self-regulating heating cable factory-terminated with a 120V power cord and plug, fiberglass tape for securing the cable to the pipe, and a complete installation and instruction guide. The kit format is designed for straightforward residential and light commercial pipe freeze protection — plug-and-play without any field splicing or electrical panel connection.
Pre-configured Outpipe 120V kits are available in 11 standard lengths: 5, 10, 15, 20, 25, 30, 35, 40, 60, 80, and 100 linear feet. Each kit includes the self-regulating heating cable factory-terminated with a power cord and plug, plus fiberglass tape and installation instructions. Kits are ready to install — no electrical connection beyond plugging into a GFCI-protected 120V outlet required.
Outpipe SR cable produces 5, 9, or 12 watts per linear foot at 50°F depending on the watt rating selected. MI cable produces up to 24 watts per linear foot. Pre-configured 120V kits use SR cable rated at 5 watts per foot. The correct wattage for a project depends on pipe diameter, ambient temperature, insulation thickness, and the fluid being protected — contact a Heatizon distributor for guidance on the right wattage for the specific application.
Choose MI Outpipe for large commercial and industrial pipe heating applications where consistent, high watt output is required across long runs — process pipes, industrial fluid lines, and large tank heating where the SR cable’s maximum output is insufficient. The MI variant is ordered to exact length before installation. Choose SR bulk cable for most residential and light commercial freeze protection applications where the SR variant’s self-regulating characteristics provide built-in energy efficiency and plastic pipe safety.
Self-regulating Outpipe cable automatically adjusts its heat output based on the temperature of the pipe surface it is wrapped around — producing more heat when the pipe is cold and less as the pipe warms. This means the cable cannot overheat and is safe for plastic pipe materials. Because output varies with temperature along the cable’s full length, a single SR cable can protect a pipe that passes through varying ambient conditions — from a warm indoor section to a cold exterior section — without any additional controls or zone management.
Yes. Outpipe SR cable is safe for plastic pipes because of its self-regulating characteristics — the cable automatically reduces its output as the pipe temperature rises, preventing overheating that could warp or damage plastic pipe materials. Outpipe is compatible with both plastic and metal pipe types including PVC, CPVC, PEX, copper, and steel.
Outpipe bulk SR cable and MI fixed-length cable carry a 10-year manufacturer warranty. Pre-configured 120V kits carry a 5-year warranty. The difference comes from the kit’s added components — the factory termination and plug — which have a shorter rated service life than the heating cable itself. The cable in both formats is identical; the warranty difference reflects the additional hardware that makes the kit plug-and-play.
Yes. Outpipe is ETL listed for the United States and Canada across all three formats — bulk SR cable, MI fixed-length cable, and pre-configured 120V kits. ETL listing is issued by Intertek, an OSHA-recognized Nationally Recognized Testing Laboratory carrying equal legal standing to UL and CSA listings in the United States.
Outpipe and GutterMelt share the same fundamental cable construction and the same three formats — bulk SR cable, MI fixed-length cable, and pre-configured 120V kits. The difference is application. GutterMelt is designed for gutters, downspouts, and roof eaves. Outpipe is designed for pipes, valves, and tanks. Both are ETL listed for US and Canada, carry a 10-year warranty on bulk and MI cable and a 5-year warranty on pre-configured kits, and use the same self-regulating technology that prevents overheating on temperature-sensitive materials.
Outpipe is Heatizon’s heat trace cable for pipe freeze protection, pipe temperature maintenance, valve freeze protection, and tank heating. It is available in three formats. Bulk self-regulating (SR) cable is sold by the foot, cut to length in the field, and available in 120V, 208V, 240V, and 277V. MI (mineral-insulated) fixed-length cable is ordered to exact project length and delivers higher watt output for demanding commercial and industrial pipe heating applications. Pre-configured 120V kits come factory-terminated with a plug, ready to install, at 5 watts per foot in standard lengths from 5 to 100 linear feet. All three formats are ETL listed for the United States and Canada.
