Radiantly Heat
Every Room

New construction, remodel or retrofit. Each system and controls are custom designed for each space.

4" - 10" Below a concrete slab

Thermal Mass Earth Storage
Floor Heating

Panels go in below the slab and turn the concrete and the ground under it into a heat battery 2 to 2½ feet deep. The bigger the mass, the longer it holds heat and the less it costs to run. It charges on cheaper off-peak power and releases heat all day.

Best for
Slab-on-grade homes, basements, shops, warehouses, factories
Role
Primary heat
ThermaRay thermal mass heating panels laid out on sand before the slab is poured at McKenzie Electric Coop

Above the ceiling

Radiant Ceiling Heat

Panels lay between trusses or rafters, just above the drywall. They warm the floor, walls and windows the way sunlight does. Ideal when you can't tear up a floor.

Best for
Remodels, retrofits, new builds
Role
Primary or supplemental

Under the subfloor

Floor Joist Heating

Panels hang between the floor joists below the subfloor, so the floor height doesn't change. A good fit over basements and crawl spaces.

Best for
Existing homes, additions
Role
Primary, supplemental or luxury

Above the subfloor or slab embedded in thin set or a self-leveling medium

Floor Warming

ThermaRay heating cable goes on top of the subfloor or an existing slab and under any flooring. Cold surfaces become a radiantly warmed floor. It's the lowest-profile cable in the industry.

Best for
Bathrooms, kitchens, slab remodels
Role
Primary, supplemental or luxury

Surface mount, hanging or T-bar grid ceilings

Architectural Series
Metal Heaters

Radiant metal heaters that mount to a surface, hang from the structure or drop into a 2×2 or 2×4 ceiling grid. entire structures or spot heating.

Best for
Garages, shops, warehouses, offices, schools, hospitals, yoga studios
Role
Primary, supplemental or spot

Under concrete, pavers or asphalt

Snow and Ice Melting

This is a limited mass snow & ice melting system. The panels are installed below the wear surface in 2"-6" of sand. The system is protected from cracking, heaving, shifting, cracks & cuts. No shoveling, plowing or chemicals that can damage the surface.

Best for
Driveways, sidewalks, ramps, entrances, loading aprons
Role
Automatic snow and ice removal
ThermaRay snow melting panels laid out prior to sand and concrete for a garage apron.

Heat the people and objects,
Not the air.

Radiant heat works like the sun's rays. The warm radiant rays travel in straight lines and warm whatever they see (People and Objects). Forced air and convection systems warm the air and that hot air rises.

  • If you're feet are warm, your whole body is warm

    Radiant heat evenly warms the space. Even if the heat is in the ceiling the floors will be warm. Your feet are the hardest part of your body to keep warm, and forced air systems only warm the air.

  • Lower heating bills

    ThermaRay systems typically cost 30% to 60% less to run than forced air, baseboard, hydronic systems.

  • Comfortable by the window

    Radiant heat warms surfaces, including the walls and windows so you'll feel comfortable in the entire space. Radiant rooms feels warmer at a lower thermostat setting.

  • No fans or blowing air

    no blowing dust or airborne contaminants. Doesn’t dry out your eyes, nose and throat.

  • Silent & Comfortable

    No air blowing, ticking baseboards or any moving parts and nothing to repair or replace. ThermaRay has 45+ years of installs with no failed systems.

  • Invisible Heating and Controls

    Most ThermaRay heating systems are invisible and now we offer invisible controls options. Premier Energy can provide a warm and healthy environment with no controls in sight.

A ThermaRay Heating System is far more cost-effective than forced-air, hydronic or convection systems

ThermaRay Electric Radiant compared with Hydronic Tubing
FeatureThermaRay Electric RadiantHydronic Tubing
Cost to installA fraction of the cost or hydronic/tubing systems. Sometimes up to 70% depending on location.Boilers, pumps, manifolds, expansion tanks, zone valves, insulation and tubing
Cost to operateDepending on power source, typically 30%-60% less cost to operateInsulation limits the thermal mass and creates higher operating costs. Constantly reheating water/glycol to maintain temperatures
Foam under the slabNot required for thermal mass earth storage systemsTypically required and adds material cost and labor to install
Off-peak electric ratesQualifies for off-peak or other control programs offered by many power companies, sometimes rebates as well. Restricted mass hydronic/tubing systems don't qualify for Off-Peak programs
Mechanical roomTakes up very little space on a wall.Many tubing systems require a separate room or considerable room in the mechanical room.
MaintenanceNo Maintenance, replacement or repairs. Silent and invisible.Yearly maintenance and eventual repairs and replacements of many components, including the boiler.

“We could never go back to living in a standard house. The extra effort was the best investment we have ever made.”

Spencer, EchoHaven homeowner, speaking to Construction Canada. Electric radiant heat in a house built to produce as much energy as it uses.

“We wanted a SMART and ENERGY efficient home. Part of that was having ThermaRay Heating Panels which created Thermal Mass and runs during off-peak hours. The savings is amazing.”

Homeowner, Durango, Colorado. A new home designed and built by the owners, heated with thermal mass panels on off-peak power.

“The Thermal Mass Storage Heating System is easy to install and well-suited to maximum demand control … We’re talking days’ worth of storage so the money you save is enormous!”

See All Questions

How much does electric radiant heat cost to run?

ThermaRay systems typically cost 35% to 70% less to operate than hydronic or forced air, depending on your power source. The manner in which we deliver the heat is exponentially increased by the Thermal Mass our system creates in a space. Electric radiant is less cost to operate than even natural gas or ground source forced air systems. Forced air and convection systems Do Not create thermal mass.

Do I need foam insulation under a heated slab?

Not recommended. Insulation limits thermal mass. The larger the Thermal Mass, the lower the operating costs. A popular misconception is that the heat will disappear into the earth and be lost energy and money. The physics of it is that if the heat was never turned off, it would keep driving the heat down, but the space above would be unbearably warm. In actuality the thermal mass created is typically 18"-30" deep because the thermostat is satisfied. Heat is like a magnet to cold and will be released into the space above when the warmth is required. Warm does not transfer to warmer so once the heat reaches a temperature equal to itself, like the temperature of the earth it does not migrate any further.

Can I or my own electrician install it?

Absolutely. Great for DIY'ers, but any electrician should be able to install any of our heating systems. It's as easy as wiring a light to a switch. Premier Energy also provides the design, drawings, videos and expertise to make any installation as simple as possible.

Can radiant heat be the only heat in a building?

Yes. All of the ThermaRay heating systems can be used as the sole and primary heat source in any climate. It can also be used as supplemental or spot heating.

Is radiant heat the same as infrared?

They're closely related. Radiant heat is any heat that travels as electromagnetic waves and warms objects directly instead of the air. Infrared is the part of that spectrum, just below visible light, that's especially good at warming surfaces and people.

What area do you service?

Premier Energy provides products and services throughout all of America. Projects range from shore to shore and border to border. We have installations in nearly every state of the country. From a shopping mall in Florida to a mountain home in Idaho to High Rise Condos in New York to Hot Yoga Studios in California.
