Heat that fits the building’s design.
A heating system shouldn’t spoil a well-designed space. Architectural Series heaters are flat metal panels that complement the building in both looks and performance.
They’re made for offices, schools, hospitals, warehouses, entrances, atriums, work areas and rooms with high ceilings. At home, they’re common in basements and garages, and they work just as well in bedrooms and living areas.
Like all radiant heat, they warm the floor, surfaces and people below them instead of the air, so a high ceiling doesn’t waste the heat.

Three ways to mount them.
Surface mount the heaters directly to a ceiling, with or without a frame. Hang them from the structure on cables or chains in shops, warehouses and high-ceiling spaces. Or drop them into a standard 2’ × 2’ or 2’ × 4’ T-bar ceiling grid in place of a tile.
They come in several voltages and wattages, so each space gets the heat it actually needs.

Where can electric radiant heaters be used?
Offices, schools, hospitals, warehouses, entrances, atriums, work areas and high-ceiling spaces. In homes they’re common in garages and basements, and they also work in bedrooms and living areas.
Can a radiant heater heat a garage?
Yes. Garages are one of the most common uses. The heaters warm the floor, the car and the people in the space instead of the air, so heat isn’t lost every time the door opens.
How are the heaters mounted?
Three ways: surface mounted to the ceiling with or without a frame, hung by cables or chains, or dropped into a 2’ × 2’ or 2’ × 4’ T-bar ceiling grid.
What sizes are available?
The most common are 24 × 24 and 24 × 48 inches. 14 × 48 and 14 × 60 inches are also available, along with custom sizes and colors.
Do they work for hot yoga studios?
Yes. Architectural Series heaters are used in hot yoga studios, including a studio in Louisville, Kentucky.
