What size area does it heat efficiently?

Works very good in our 225 sq ft room. Room has full glass on the north side. Hope this helps.

Exactly, I am not sure; but it heats a 300 sq ft room on my house very well.

My room is 20 feet by 20 feet, so 400 sq ft. While i dont have a thermometer in there to gauge temps, the estimate in my review was based on the temp from our car and the temp at which we set the Dyson to. It raised our room about 5 degrees in about 30 minutes and it was an even heat throughout the room. Having said that, it is too soon to know electric bill implications.

Approximately 12 inches by 12 inches. Heats really well and will automatically turn off when warm enough. Also has a fan to use without heat if needed. This will shut off if tipped over. Very quiet. I love this heater and heats a room very quickly.

it's a good three inches in diameter... a good amount of space to heat up!!

I'll say my tiny bathroom (6x6) still takes about 15 or more to get even some fealing of heat. Im acually looking for a better heater now..

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.

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 have not needed to heat anything yet (I live in FL) but a 14 x 14 space should easily be heated by this unit.

25 x 25= 625 sq ft. This heater is rated for an area that would be around 1100-1200 square feet. In your smaller space, this would be a lot of heat and you would have a real ventilation problem unless you had open window or doors leading from this space. A smaller heater rated at around 10,000 btu would be best for you.

We have this heater installed in an open area of our home that is 2 levels (a drop of 2 steps to the lower level) and approx 30 x 40 with an open beamed ceiling. An open hall leads off upper area and there are open doors to other rooms. It takes the chill off the entire 1500 sq foot house, is not very effective in the back 3 rooms of the house, but keeps the upper area where it is installed (30 x 20) very comfortable. I definitely would go bigger if you want it to heat your entire house, but it's great for smaller areas. It is economic to run. We are very happy with it.

It is very small for the amount of heat it puts out. 10 1/2 W x 15 3/4 H (on castors) x 12 1/2 deep.

The cooking area is 4 burners. Not huge but sufficient for my family needs. Please see the Swiss Grill website for exact details.

We use it in a 6' x 8' bathroom and it heats GREAT on a low setting. On a higher setting, it also warmed a small hallway. BTW, I wouldn't order this from Amazon Deals. Both ordered had considerable cosmetic damage (in spite of being described as "like new"), one had a cover so bent it wouldn't stay on. However, the new one looks and runs great--I'd buy again.

Well depending on what floor you have. I have it in my dinning room that is 14x14 sq foot and its amazing what this thing does. On carpet I don't think its that efficient but still does a great job i highly recommend this heater. Remember placing the heater in the right place is the key. I love it. Rating it 5 stars

Our room in the basement is approximately 20x25 and it heats it very well. It pretty much helps the whole basement (700 sqft) feel warmer. I love it!

I have this unit in my office. When I want it to really continously heat the room if I'm just cold from sitting so long, I turn the dial 3/4 of a turn and it runs and fills the room with warm air. I have experienced absolutely no problems with it running continously, warming the room, which is about 11 x 9. This unit is quiet, very slim profile and a very sufficient way to heat this small area. Great purchase, very satisfied.

definitely a master suite size room. i live in a studio garage apartment (basically a 2 car garage) and it heats the place nicely.

This works for small spaces, like under a desk. I use it in my RV bathroom and it heats that up quite nicely. However, it's too small to heat a larger room. It has a dial where you can set it to whatever temperature you want and have it maintain that temperature. In my RV, I have it set for medium (about halfway around the dial) and RV Bathroom is quite toasty. Not sure how to answer for "cost efficiency" other than to say only use it in SMALL rooms.
