How many cubic feet of room can this heat?

I've been using it in my living room (24 X 12) and it keeps the hall and kitchen warm as well. The heating is directly proportional to how well the home is insulated.

It depends on location in the US and the extent of existing insulation of the specific room. It will keep a room 12'x15' with two outside walls insulated with R-13 comfortable (room door is closed) when the outside temperature is 25 degrees F using the low setting.

I don't remember but it's in the specifications. I use mine in a 17 x 27 room and it makes a big difference in there. I have a 2nd one that I use in my 15 x 17 bedroom and have to turn it just below medium or it's too warm. What I like best is how quiet they are.

I have in a room in the garage that is 8x20ft and no problem in getting this room to 70F, takes about 10 minutes and stays there until I shut it off. Have seen other comments about this heater for room sizes up to 200 sq ft.

Per the manual 3 feet of clearance around the top in all directions is required. I would recommend more however since this unit has nearly 50,000btu so it can run HOT! You can warm a 10' x 10' area with just one unit.

Not sure. It should heat a 20' x 20' room very well. You also can take it off "Auto" and it will run all the time and not try to get to its set temp. If the air coming off the machine while it is running isn't hot, then your unit is defective.

I don't know the maximum room size for this heater. From my experience during this winter, one heater nicely heats a well insulated 200 sq.ft. room in Albuquerque, NM. I have two of these heaters in this room and no other heat. This has been more than necessary, but the units don't run very long and they are surprisingly quiet. I have been happy with these heaters.

As long as you have enough space around the heater so not to start a fire. Blows out a good 10 feet, its keeping a space very warm that is about 500sq feet and it is -30 here.

I heat 900 square feet insulated garage in bitter cold northern Minnesota on the 1st setting. I have had to turn it up to 2nd setting for some people to be comfortable. Its a great heater very happy with it.

I use it in a three car garage(720 sq ft) to take the chill off when I'm working out there. It works out quite well for me. I like it and myself I think it would heat a 20x13 room.

I am heating a basement room 16x24 with a 10 ft ceiling and it does a great job. I use the economy setting which allows us to drop the heat by several degrees. Also you can set the on- off times so it doesn't have to waste heat during the night. My unit is the EX 17 (BTU) Natural Gas model.

I used Mr. Heater in an area approx. 400 square feet. After about 40 minutes I had to turn it way down. I would say this would heat an area at least twice that size, to a comfortable temp.

We use it in a room that is about 12' x 16'and it heats it almost to much on high. Our winters here only drop to about 30 degrees though. We have two. They heat great, but do use more energy that our regular heat pump. We use these when our heat pump goes out. (We are in AZ)

basically takes up only 1 cubic foot of space!...but heats up my 24 X 16 shop great with no insulation..40 degrees outside ..turn it on and it will get my shop up to 80 degrees in an hour!..great heater!

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.

We're currently heating an area about 25 X 30 with only partial walls due to the structure. We have an open ceiling and a storage area beside the room of approx. the same size. It keeps the training area comfortable. I would be comfortable saying it can handle 1200 square feet without a problem. It might cover more if the room was totally enclosed.

I use it to heat an office approximately 13 ft by 13 ft. It works great for that small space, but you would probably have to turn the temp up pretty high if you were trying to heat a much larger room or one with very high ceilings.

Same square footage as yours. This heater puts out only a mild heat that will dissipate quickly in bigger rooms, with possibly large or multiple windows. The smaller the space the better it works. It struggled to keep up a satisfactory temp in a space the size of ours. High ceilings probably didn't help my situation either. I placed mine in a bit smaller room and it works wonderfully.
