1500 wattts -- estimate square footage of room that it'll heat comfortably?

20x20 is what I have been using it for and it can get two hot. I think it would heat a large bedroom effectively. It's a great heater. The best space heater I have bought. It's quiet and the side separates so you can aim the heat in different areas.

180 sq. ft. at my house, but a lot depends on how cold it is outside and how well the room is insulated.

One watt = 3.41 BTU's. A 1500 watt heater will produce 5115 BTU's/hr. and at 800 watts will produce 2728 BTU's. A great money-saving alternative to heating the entire home, this portable electric heater delivers comfortable warmth wherever it's needed most. Designed for a large 16-by-16-foot room with an 8-foot ceiling, the unit's energy-efficient Vortex technology fully circulates warm air throughout the room in just minutes. Choose from two heat settings--low at 800 watts or high at 1500 watts. For added convenience, its automatic climate control adjusts the heat output and fan speed at all times to maintain the set temperature, which means the room doesn't need to cool down in order for the heater to turn back on. Great for at home or at the office, the unit offers simple top-mounted controls, whisper-quiet operation, and a variety of safety features including a cool-touch cabinet and grill, a non-glowing heating element, and automatic shut-off for peace of mind. Model is made for 120 Volts only. I use mine in my motorhome which is 8.5' x 37' and it does a good job in the front 2/3rds. of it. When the outside temp falls below freezing it struggles to maintain 70 degrees but a motorhome is not very well insulated and has lots of window glass to transfer cold. I am very pleased with mine and recently purchased another one. There are cheaper heaters on the market but I haven't found any that out perform this one.

There are two heat settings; low and high. They probably correspond to 1500 and 750 watts output. The thermostat will work with either setting.

I would say 600 or 700 square feet easy. If you ran it full blast it might heat more. I keep mine on 68 most of the time.

HiI used the u it for a medical spa room where a high power laser emits lots of heat energy. I have standard cooling but it was quite insufficient for my purpose. This suint has made it so much better for the room and my main unit dosent have to be revved up before and after the procedures. The room is about 16x16. So it shall be fine for your 15x15 room.

700-800 sq. ft. Heats that size area very well on low. Can't turn higher cause it gets too warm in the room !

For a space of 60 sq ft....I doubt it'll have an immediate warmth impact....You may feel warmth after a few hours of use...If your looking for a high output portable heater...Allow me to suggest "The Big Heater Buddy" ...It'll put out btween 4000-9000 Btu's... Check Cabelas website...The deal with refurbished units....Good Luck.

I have one in the bedroom and it can heat more than that. The room is probably 12'x12'.

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.

I agree, with the other answer. You would be asking way TOO much for this little 180 Watt unit. It does a great job for me heating a small compartment of my motorcoach where the water pipes come into the coach.

All heters are the same really. 1500 watts is 5000 BTUs and it doesn't matter much after that. 13x14 worked fine for me but it depends on house insulation, and outside temperature. It was also supplemental, as the centeral heater was holding the rest of the house at 63.

Oh, I forgot to mention that it might take a couple of house to heat up a room of 1000 square feet. So, the rating is way off. It should be some where like 400 square feet instead of 1000 like they advertised it.

It heats up well, but I use it mostly for instant heat rather than heating up the room, since it is a fan forced type. I guess, if you're going to use it for the main heater, about 10X15 would be the maximum you can get, without other heating source.

Yes it would heat a 700 sq ft room. I have used ours at the end of a hall way approx 50 feet away from our main heater which is a Monitor oil stove and sits in the living room. I have never checked to see how much less electricity is used in our home but will say, we must lower the heat settings in the living room. We are very satisfied with the lifesmart 1500. Keep in mind that it will take a little time to heat the air in the room but I think its great.

The manual states "at 1500 watts, your heater will use approximately 5100 BTU." I wish I could be more helpful. I bought my heater at the END of last winter and have not yet used it, but hope to beat the high costs of electric heat this coming winter.

1500 watts = 5119 BTU/hr but the actual electrical current used and converted to heat varies with the line voltage. The 1500 watt rating probably assumes a line voltage of 120v. I would assume about 5000 BTU/hr.

Heats my entire room without any additional heat source. Room is approximately 800 sq ft.
