In general, one square foot of space requires about 10 watts of electricity to heat, which means that a space heater operating at its maximum output can heat a room no larger than 150 square feet.

Are infrared heaters 100% efficient?

100% efficient at point of use

Infrared heaters get their power directly from the mains, so there are no system losses like you'd find in a fuel-based system. As they convert every watt of energy into radiant warmth, you're never paying for waste.

Do infrared heaters dry out the air?

That being said—radiant heaters like infrared floor, wall, and ceiling heating systems directly convert electrical energy into heat without affecting air moisture levels. They transfer warmth to boundaries such as floors, walls or ceilings. By doing so, they warm up surfaces in the room instead of the air.
