A 1000 sq. foot well insulated house in a temperate climate (not Ohio) would need about 45,000 btus of heating or nine of those heaters. I believe the ruse they use is to say that it will heat just the room you are in so you can turn down your main furnace to 60 degrees then the electric heater only has to heat from 60F to 70F and not from the 20F outside temperature.sylvie said:I see them for $349 that heat 1000 sq feet.
They are only approximately 15"x15"x17" and heat by infrared. Are they worth it? Too good to be true? That seems terribly small to heat a room that size.
