AFUE (Annual Fuel Utilization Efficiency) –
AFUE is a rating for combustion heaters such as boilers, hot water heaters, or forced air heaters. It is the ratio of annual output energy to annual input energy.
Ambient Temperature Sensor –
The temperature of something surrounding something else, i.e. The ambient temperature of a room is the temperature of the air surrounding a mechanism to measure temperature.
Anchor Plug Kit –
A kit which allows for the installation of wire onto a concrete surface. Holes are drilled into the concrete, wooden dowels are inserted into the holes and nails are then used to attach wire clips to the wooden dowels.
AutoCAD is a suite of CAD (Computer Aided Drawing) software products for 2- and 3-dimensional design and drafting, developed and sold by Autodesk, Inc.. The original concept of AutoCAD in the 1980s was to promote customization and feature extensibility, and was what made it especially appealing to customers.
AWG (American Wire Gauge) –
The standard method of denoting wire diameter. The larger the gauge, the smaller the wire. For #14 gauge wire, the gauge is the number of bare wires that, when placed side by side, are 1 inch wide.
The British thermal unit (BTU or Btu) is a unit of energy used globally in the power, steam generation and heating and air conditioning industries. Although it is in common use in these industries, in scientific use it has been replaced by the SI unit of energy, the joule (J). In North America, the term “BTU” is used to describe the heat value (energy content) of fuels, and also to describe the power of heating and cooling systems, such as furnaces, stoves, barbecue grills, and air conditioners. When used as a unit of power, BTU per hour (BTU/h) is understood, though this is often confusingly abbreviated to just “BTU”. In the UK and other parts of the world it is written BTU. One Watt is equivalent to 3.41 BTU/hr.
Building Code –
A building code is a set of rules that specify the minimum acceptable level of safety for constructed objects such as buildings and nonbuilding structures. The main purpose of the building codes is to protect public health, safety and general welfare as they relate to the construction and occupancy of buildings and structures.
CADD (Computer Aided Design and Drafting) –
Computer-aided design and Drafting (CADD) is the use of a wide range of computer-based tools that assist engineers, architects and other design professionals in their design activities. It is the main geometry authoring tool within the Product Lifecycle Management process and involves both software and sometimes special-purpose hardware. Current packages range from 2D vector based drafting systems to 3D solid and surface modellers.
Castle Chairs –
Castle Chairs are used to raise heating element attached to welded wire fabric closer to the surface of the new pour concrete. By so doing it can improve snow melting/slab warming efficiency.
Cathode Ray Tube –
A Cathode Ray Tube (CRT) utilizes electrons and magnetic fields to display images on a screen. Older model televisions and computer monitors use this technology. The use of a magnetic field in the CRT makes it susceptible to distortion caused by other electromagnetic fields that occur near/around them.
Caulk is used to seal ships, buildings, or other surfaces to make them water tight. It is specifically used with radiant heating systems to seal asphalt or concrete surfaces after a snow melt system has been retrofitted into them.
See Castle Chairs
Chalk Line –
A Chalk Line is used to create straight lines over a long distance. A length of string, saturated in chalk, is stretched across the distance to be marked. The string is pulled tight and each end is pressed against the surface to be marked at beginning or ending points. The middle of the string is then pulled away from the surface to be marked while the end points remain pressed against the surface. The middle is released and strikes the surface to be marked, leaving a straight line of chalk on that surface. In outdoor conditions a clear polyurethane will be sprayed over the line to protect it from rain and snow. Chalk lines are frequently used by Heatizon Installers to mark where grooves should be sawcut in retrofit applications.
Cold Joint or Mark –
A cold joint or mark is a joint or cut which allows for the vertical and/or horizontal expansion and contraction in concrete. Running the tubing or cable of a snow melt system through a joint of any kind is potentially hazardous to radiant heating systems. A Joint Jumper is generally used to prevent damage to a radiant heating system.
Cold Lead –
Cold lead conducts electric current from the control unit or activation device to the heating element of a radiant heating or snow melting product. It has very little resistance to reduce the loss of heat and power over the distance traveled.
Combustion Efficiency –
Combustion Efficiency is the efficiency in a boiler, hot water heater, or forced air heater. It refers only to the possible output of heat, and not the actual heat output. It only accounts for heat loss through the exhaust flue.
Concrete consists of cement, aggregate, and water. Water reacts with the cement and produces a chemical reaction that binds the cement and aggregate producing a stone like material. It is used in the construction of buildings, driveways, walkways, roadways, etc.
Control Unit –
The control unit monitors the operation of a radiant heating, snow melt, floor warming or roof deicing system. It has built-in safety features to monitor for overcurrent and undercurrent or short in the Tuff Cable or ZMesh radiant heating element.
Crimping Tool –
A crimping tool is used to crimp or attach a wire to some other object such as a Tuff Cable butt splice, E210 butt splice or ZMesh Transition Plate. The wire is placed inside that object and the crimping tool is used to squeeze that object tight around the wire.
Cut Out Kit –
A cut out kit allows for ZMesh to be used in a location where a hole exists in the flooring that cannot be covered with ZMesh such as a drain, electrical circuit or vent. A portion of the ZMesh is cut to fit around the hole and a copper plate is used to facilitate the flow of the electric current.
Detailed Drawing –
Element Test –
Heatizon Systems recommends that an element test be conducted at numerous different times of an installation process. An element test will check for electrical continuity in a systems and will help insure that the systems has been installed without any damages.
Elevated Sleepers –
Elevated Sleepers are used to raise up or provide a nailing area for hardwood flooring. When most other floor heating or floor warming products are installed (other than Heatizon Systems ZMesh), sleepers are essential whenever a mud bed is required for hydronic and high voltage radiant floor heating systems because they create an area to place the heating element or pex tubing.
Enclosure Kit –
An Enclosure Kit is used to house one or two Control Units in an outdoor area. It is designed to protect the electric components from the elements and allows for the dissipation of heat.
A Fault is any condition that turns off the control unit and turns on the fault light. It most commonly occurs when one or more conductors of electric current short to each other or find a path to ground.
Floorizwarm is one of Heatizon System’s low voltage radiant heating systems. It utilizes a step down transformer and Heatizon System’s Floorizwarm Tuff Cable to provide, low voltage, cost effective radiant heat. It is particularly applicable to small areas. Various Floorizwarm system models are available, and are capable of heating from 15-110 square feet.
Floor Temperature Sensor –
A Floor Temperature Sensor is used in radiant floor heating applications to measure the temperature of a floor. It is used to activate a radiant floor heating system should the temperature of the floor drop below the desired temperature.
A GFCI or Ground Fault Circuit Interrupter is an electrical wiring device that disconnects a circuit whenever it detects that the flow of current is not balanced between the phase (“hot”) conductor and the neutral conductor. The presumption is that such an imbalance may represent current leakage through the body of a person who is grounded and accidentally touching the energized part of the circuit. A shock, possibly lethal, is likely to result from these conditions.
Green Building –
Green building is the practice of increasing the efficiency of buildings and their use of energy, water, and materials, and reducing building impacts on human health and the environment, through better siting, design, construction, operation, maintenance, and removal — the complete building life cycle.
Heat Loss Calculation –
A heat loss calculation is determined by the type and amount of insulation and materials used to construct a building. It determines the ability of a building to hold heat in and calculates how much heat/energy must be put into a home to keep it warm.
A Heatsink is a material with high thermal conductivity. It facilitates the transfer of heat from one medium to another. Heatsinks commonly used in radiant heating applications are: sand, thinset, mortar, concrete, asphalt and a Heatizon Heatsink Kit.
Heatizon Heatsink Kit –
A Heatsink Kit is a patented application. A Heatsink Kit facilitates the installation of a radiant heating cable on a roof but under the roofing material. It can also be used on floors and decks when needed. Heatizon Systems Heatsink Kit uses a layout of Heatsink boards to allow a radiant heating product to be installed on a roof and in a heatsink at the same time.
Heat Trace –
High voltage heating cable used in gutters and downspouts to prevent ice and snow buildup. Prior to Heatizon Systems roof snow melt and deicing products, Heat Trace was used in a “zig zag” fashion on roofs to provide a channel for melted snow and ice to travel in.
The term insulation can refer to materials used to reduce the rate of heat transfer, or the methods and processes used to reduce heat transfer. Heat is transferred from one material to another by conduction, convection and/or radiation. Insulators minimize the transfer of heat energy. In home insulation, the R-value is an indication of how well a material insulates.
Invizimelt is a Heatizon trademark and brand name for a heatsink system used for Tuff Cable. Invizimelt is an aluminum panel that Tuff Cable snaps into allowing a rapid heat transfer compared to traditional heatsink and cementitious based substrates. Invizimelt can be used for roof deicing and under decks and other surfaces.
See Cold Joint or Mark
Joint Jumper Kit –
A kit which is used to prevent damage to Tuff Cable heating element by avoiding running it directly through joints and marks in concrete. The kit connects the Tuff Cable to cold lead and runs the cold lead under the concrete where the joint or mark exists and then connects once again to the Tuff Cable.
Leads, Cold –
See Cold Lead.
See Cold Joint or Mark
Magnetic Field –
In physics, a magnetic field is a force field that surrounds electric current circuits. A magnetic field can also be found in the vicinity of ferromagnetic materials such as iron. The existence of a magnetic field is ascertained by its effects. The most important of these effects are (1) Force on a moving electrically charged particle, (2) Force on a stationary charged particle when the magnetic field is changing, (3) Mutual force acting between two objects or electric current circuits that are surrounded by a magnetic field.

On Center –
On Center denotes the way that a distance between two objects should be measured. In the framing of a home, studs are placed sixteen inches on center. This means that from the center of one stud to the center of the other stud is a total distance of sixteen inches.
also called Gudle, is a traditional Korean underfloor heating system for indoor climate control.Ostensibly it is comparable in principle to a Roman hypocaust, but differs in that the prototype of Ondol was originally intended to circulate heated air, for both cooking and floor heating, while hypocaust was to circulate heated air under the stone platforms in public baths.
A paver is a brick-like piece of concrete commonly used as exterior flooring. In a factory, pavers are made by pouring a mixture of concrete and some type of coloring agent into a mold of some shape and allowing it to set. They are applied by pouring a standard concrete foundation, spreading sand on top, and then laying the pavers in the desired pattern. No actual adhesive or retaining method is used other than the weight of the paver itself. Pavers can be used to make driveways, patios, and other outdoor platforms.
Pole, Single and Double –
A single pole breaker is the breaker used for 110 volt power. A double pole breaker is for 220 volt power. It is designed as two single pole breakers connected together and feeds two sources of 110 volt power into one to make 220 volts. It is designed so that if one of the two 110 volt breakers trip, it will automatically trip the second.
Programmable Thermostat –
A programmable thermostat is a thermostat which is designed to adjust the temperature according to a series of programmed settings that take effect at different times of the day. Programmable thermostats may also be called setback thermostats or clock thermostats.
Radiant Heat –
Radiant is a heating system which uses electric resistance wire, mesh (or hot water in pipes) to heat the floors, walls or ceilings of a room. The technology has existed since the Roman use of Hypocaust heating. The heat energy is emitted from a warm element (floor, wall, overhead panel) and warms people and other objects in rooms rather than directly heating the air. The internal air temperature for radiant heated buildings may be lower than for a conventionally heated building to achieve the same level of body comfort (the perceived temperature is actually the same).
Renewable Energy –
Renewable Energy is energy derived from resources that are regenerative or for all practical purposes cannot be depleted. For this reason, renewable energy sources are fundamentally different from fossil fuels, and do not produce as many greenhouse gases and other pollutants as fossil fuel combustion. Mankind’s traditional uses of wind, water, and solar energy are widespread in developed and developing countries; but the mass production of electricity using renewable energy sources has become more commonplace recently, reflecting the major threats of climate change, exhaustion of fossil fuels, and the environmental, social and political risks of fossil fuels. Consequently, many countries promote renewable energies through tax incentives and subsidies.
The installation of a new product into or on an already completed project. For example, retrofitting would be to install a radiant heat system into existing concrete without removing or replacing concrete.
Roof Alarm –
A Heatizon Systems Roof Alarm is used when installing ZMesh or Tuff Cable on a roof. Since roofs are built with many different electrically conductive materials (flashing, rain gutters, drip edge, roof straps, etc.) A roof alarm will insure that the heating element is never shorted to any other conductive material while the roofing is being installed.
The process used to prepare a site for a radiant heating system. It generally consists of the installation of cold leads, thermostat wire, and wall mounting mechanisms and primary power supply.
R -Value –
The R-value is a measure of thermal resistance used in heat transfer problems. The SI units for thermal resistance are K·m²/W. R-values are commonly used to characterize thermal insulation materials in buildings.
Grooves cut in concrete or asphalt which are used in retrofit instalations. Radiant heating cable is then placed in the grooves and a caulk is used to fill in the grooves over the heating cable
A diagram that represents the elements of a system using abstract, graphic symbols rather than realistic pictures. A schematic usually omits all details that are not relevant to the information the schematic is intended to convey, and may add unrealistic elements that aid comprehension.
Selector Box –
Heatizon Systems uses a selector box in conjunction with another activation device to prevent numerous electric radiant heating systems for turning on at the exact same moment. If numerous systems all turn on at once the startup current can trip the breaker to your home.
Self Regulating Cables –
A form of electric heat tracing cable most commonly used for freeze protection that has power output as a function of the temperature at any location in the element. The result is that the output of the heater decreses as the temperature rises. (see GutterMelt)
Sensor, Moisture/Temperature –
A sensor that is used in snow/ice melting applications to monitor the exterior temperature and moisture content of the air. When moisture and a near freezing temperature are sensed, the sensor activates the snow melting systems before snow and ice accumulate.
In electrical devices, unintentional shorts are usually caused when a wire’s insulation breaks down, or when another conducting material is introduced, allowing charge to flow along a different path than the one intended.
The International System of Units (abbreviated SI from the French Le Système international d’unités) is the modern form of the metric system. It is the world’s most widely used system of units, both in everyday commerce and in science.
Slab on Grade –
Slab-on-grade foundations are a building engineering practice whereby the concrete slab that is to serve as the foundation for the structure is formed from a mold set into the ground. The concrete is then poured into the mold, leaving no space between the ground and the structure. This type of construction is most often seen in warmer climates, where ground freezing and thawing is less of a concern and where there is no need for heat ducting underneath the floor.
Snow Load –
Snow Load is the force exerted on roof structures by the weight of accumulated ice and snow. Snow Load requirements vary dramatically by geographic location of the project, characteristics of the building or its location that influence the accumulation of snow and ice on the roof structure and the water content of the snow.
A solder is a fusible metal alloy, with a melting point or melting range of 180-190°C (360-370 °F), which is melted to join metallic surfaces, especially in the fields of electronics and plumbing, in a process called soldering.
Specification – (Also Called Specs)
A part of the manufacturer’s documents, typically used by engineers and architects, consisting of written details of materials, equipment, products, methods, standards and workmanship.
System Operating Tables –
Heatizon Systems’ System Operating Tables list Transformer sizes and the amperage/wattage values that they will operate at using varying lengths of Tuff Cable or ZMesh element. These tables may be used as a general guild in selecting the proper voltage tap for use with the specific length of heating element that your particular installation requires.
A thermostat is a device for regulating the temperature of a system so that the system’s temperature is maintained near a desired setpoint temperature. The thermostat does this by controlling the flow of heat energy into or out of the system. That is, the thermostat switches heating or cooling devices on or off as needed to maintain the correct temperature. Thermostats can be constructed in many ways and may use a variety of sensors to measure the temperature. The output of the sensor then controls the heating or cooling apparatus.
A timer is a specialized type of clock. A timer can be used to control the sequence of an event or process. In radiant heating applications, timers can be used to manually turn on a system and then automatically turn it off after a set amount of time.
A transformer is a device that transfers electrical energy from one circuit to another by magnetic coupling without requiring relative motion between its parts. It usually comprises two or more coupled windings, and, in most cases, a core to concentrate magnetic flux. An alternating voltage applied to one winding creates a time-varying magnetic flux in the core, which induces a voltage in the other windings. Varying the relative number of turns between primary and secondary windings determines the ratio of the input and output voltages, thus transforming the voltage by stepping it up or down between circuits.
Underwriters Laboratories Inc. (UL) is a not-for-profit, privately owned and operated product safety testing and certification organization. Based in Northbrook, Illinois, UL develops standards and test procedures for products, materials, components, assemblies, tools and equipment, chiefly dealing with product safety.
The watt (symbol: W) is the SI derived unit of power, equal to one joule per second. A watt also refers to the amount of heat that is given off by an electric radiant heating system. The power of a system can be calculated by multiplying the voltage (see Volt) by the current (see Amp).
Welded Wire Fabric –
Welded wire fabric is often placed in concrete to provide strength and add reinforcement. It is used often with Heatizon Systems Tuff Cable. Tuff Cable is attached to the welded wire fabric and the fabric is then settled 2-3 inches below the surface of the new concrete to provide maximum efficiency.
Heatizon Systems ZMesh is a bronze screen similar to that found in screen doors that is used in Radiant Heating Applications. ZMesh is designed to go on a wood or concrete subfloor or subroof, and under any non-conductive floor or roof covering.
Zoned Heating –
Zoned Heating allows for temperature variability throughout a building or home. Zoned heating uses numerous zones, each with their own activation device. Each zone can then be adjusted to the desired temperature.
