UL 508A certified panel shop — custom control panels engineered to project specifications. 120V to 480V. GFEP or non-GFEP. BMS/BAS integration. All enclosure types. Standard panels available for immediate shipment.
Heatizon is a UL 508A certified panel shop — one of very few radiant heating manufacturers in the United States licensed to engineer, assemble, and list custom control panels to the UL 508A standard for Industrial Control Panels. Custom panels are engineered to project-specific voltage, circuit, enclosure, activation, and integration requirements — shipped complete with wiring diagrams and backed by full end-user support. For straightforward installations, Heatizon also offers a complete line of standard off-the-shelf panels with GFEP protection, ready to ship.
What UL 508A certification means for your project
UL 508A is the governing standard for Industrial Control Panels — the certification required for panel assemblies that integrate breakers, relays, indicators, and controllers into a listed unit. For commercial and industrial radiant heating projects subject to electrical inspection, a UL 508A listed panel is typically required. Heatizon’s panel shop designs and builds to this standard, meaning every custom panel ships as a listed assembly verifiable by inspectors and authority having jurisdiction — not a field-assembled collection of individual components.
Custom panel capabilities
Heatizon custom panels are engineered to each project’s specific requirements:
- Voltages: 120V, 208V, 240V, 277V, and 480V
- Breakers: GFEP or non-GFEP, sized to circuit loads
- Enclosures: All types — NEMA-rated stainless steel, standard, indoor, outdoor, and wet location
- Activation integration: Snow and ice sensors, temperature sensors, moisture sensors, programmable thermostats, and manual overrides — single activator or independently zoned per circuit
- BMS/BAS integration: Panels can relay current monitoring, fault signals, and activation status to Building Management and Building Automation Systems
- Project-specific controls: Custom indicators, switches, and controllers configured to project requirements
- Documentation: Complete wiring diagrams and full end-user support included with every panel
Multi-circuit configurations
Custom panels can house multiple breakers inside a single enclosure for large installations requiring multiple heating circuits — snow melting, floor heating, roof deicing, and heat trace circuits can all be managed from a single panel. Activation can be configured with a single activator controlling all circuits for uniformity, or with independently zoned activators per circuit for maximum operational flexibility.
Standard off-the-shelf panels
For projects that don’t require custom engineering, Heatizon’s standard panel line offers GFEP-protected panels with indicators, available for all voltages across a range of breaker sizes — in stock and ready to ship. Standard panels are appropriate for straightforward single or multi-circuit installations where project-specific customization is not required.
Why UL 508A matters
Most radiant heating manufacturers ship heating cable, thermostats, and relay panels as separate components, leaving electrical contractors to assemble the control panel in the field. Field assembly produces no listed panel — which creates complications for inspection, warranty, and liability on commercial and industrial projects. Heatizon’s UL 508A certified panel shop produces a complete, listed panel assembly engineered to the project’s specifications before it leaves the facility.
The UL 508A certification is issued specifically to the panel shop facility and the personnel in it — it is not a product certification but a manufacturing credential. Maintaining UL 508A certification requires ongoing compliance with UL’s manufacturing and quality standards. It is one of the most meaningful credentials available to distinguish a professional engineering capability from a product reseller.
From heating cable to control panel — a single listed source
Every Heatizon custom panel is designed around Heatizon’s own ETL-listed line-voltage heating products — Hott-Wire, GutterMelt, Outpipe, and Cozy Heat. For commercial and industrial projects requiring a complete, listed radiant heating system from heating element to control panel, Heatizon can supply and engineer every component from a single listed source. The panel is designed to the heating system, the heating system is designed to the load, and both ship together with full documentation.
Built by Heatizon — US manufacturer since 1979
Heatizon Systems has manufactured electric radiant heating products in the United States since 1979. The Custom Panel Builds service extends that manufacturing capability from heating cable to control panel engineering — bringing the same project-specific design approach that underpins every Heatizon heating system to the electrical control panel that manages it.
Frequently Asked Questions
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.
