How big of a room does it cover/warm up?

I use it in a 10x20 room that has no insulation (1934 house) and it does great! It doesn't make the room hot but it definitely takes the chill off. I already bought another one for this winter!

We use it in a 15x30 with vaulted ceilings (imagine an attic ceiling that's sloped up to 20'), and it gets up to 71-degrees when it's 40-degrees outside. Even on freezing nights, it takes the chill off and can raise the temp of the room to 68-degrees.

It covers about average size living room about 12' x 12' room, hope that helps.

I would look for something larger. That is about the size of the room I use it in and it really just warms the space around the heater - where I sit.

My room is very big and open with 14 foot ceilings and windows from floor to ceiling. It only heats about 8-10 feet from my couch which is against the wall. My area is very open through to the kitchen and dining area. So the heat does not carry far.

I have mine in a sunroom. It is about 10x11. It can go in a larger room, our sunroom gets cold with a lot of windows so this makes it nice a warm.

I use this in a bedroom which is above a garage which keeps it nice and warm. The room is 16 x 24.

Greetings James, the room I have this unit in is about 2400 cubic ft and it does NOT keep the whole room at 65-70 deg only an area of approximately 8' x 8'. It really is good for a small bedroom. I use it to warm the sofa/seating area around the TV but beyond that I'd have to use the house heater. I got this to avoid having to use the house heater due to cost. It does the job for the small area only. Ciao, TLM

Rated for 1000 sq feet but I am not sure how warm it could keep a room of that size. I am using to heat an office area within a larger room and it works well.

Depends on a lot of factors, especially insulation but assuming its well insulated I'd say a 10x10 room would be a max size. It's more of a supplementary heat than a main heater... unless you're heating a dog house! ;)

Don't know about room size, but my desk area is approximately 10 x 6 and it heats the whole area up nicely, especially under my desk where it sits.

It will cool up to a 400sq. ft. room, which is not at all very big. This unit is horrible and do not make the mistake of buying it. It simply does not cool.

It takes it a while to heat a 14x14 room. I wish I had bought a larger unit.

I am using it in a 10 x 12' or 12 x 12' room and it works great. Sometimes gets the room a little too warm, so I think it could probably heat a slightly larger room effectively as well.

I would say at least 3-4 feet, but , for the money your spending , I would purchase an infrared heater which is cool to the touch and heats the room just as good if not better.

A room about 10 ft long by 13 to 15 ft wide (130 -150 square feet) with average insulation. The 475 watt envi heater has been specifically designed to heat an average room measuring 130 - 150 square feet in floor area, to between 68 and 72 degrees, even in the coldest parts of the country. In rooms that have one or more of the following conditions: inferior insulation, many windows, staircases leading upwards, adjoining rooms that cannot be closed off (open plan) or outside entrances - this ratio may have to be lowered slightly. For rooms with above average insulation or warmer climates this ratio might be able to be increased. You can add as many heaters as you like to heat any size room, home or office. For rooms with no insulation or for rooms such as sunrooms with entire walls made of glass we recommend a ratio of one 475 watt heater per 60-80 square feet of floor area.

While I can't say exactly, it kept living/dining/kitchen area, hall and bath in our condo warm in western PA. Guessing that was about 500 square feet. I really liked this heater a lot. Have since moved and no longer have it but will be getting another one.

I heat a 24 x 24 garage with 10' ceiling. Works great, but a bigger heater would be advised for a 30x40 building. Also depends on your location and what you have for heat loss.
