With only 400 Watt, how effective is it in actually heating a mid size room?

I put one of these in our always cool, 14x20' lower Family Room. While it has made a somewhat noticeable difference in temp, I'll probably add at least one more. The information supplied by the manufacturer seems to be accurate regarding the size of room and number of units needed. Also, these things provide what I would call " ambient heat". There is no sound, movement, blowing air, etc. just a warmth that emanates from the unit. It kind of fools you into wondering if it really works, but it does!

Not very.... I live in New England and I use 1 to supplement baseboard heat to poor results.... I'm going to add a zone to my hot water system...

It depends on several factors-how cold it is outside, exact room size, etc -but mainly depends on how well insulated your room is. If your room is well insulated, within an hour your room should be quite warm.

I use mine in a finished barn that has electronic equipment, and I turn it on only when the outdoor temperature is below around 25. It will bring the temp up to about 30 when the outdoor temp is about 10. So it does what I want, but it won't do the whole job. I have propane for that. Hope this helps

take 4 100w bulbs and turn them on. you are getting about that much heat out of this heater at best. watts are watts people there is no free lunch.

It is especially effective as a supplementary heater and provides a nice even heat.

Unless you live in the south this heater can not be a main source of heat in the room. I use it keep bedrooms warm during the winter time in addition to HVAC. You use it as a main source of heat if you put two-three of these in your room. I have a neighbor who uses two heaters for his living room.

have to use this combined with baseboard heater in a small room, cant use it by itself.

Not effective in a poorly insulated room or house. I bought three of these and four of the larger 600 watt heaters two years ago. The 400 watt heaters will be given away, but the 600 watt heaters work pretty well in my small bathroom and bedrooms.

Each panel will effectively heat a 10x12 room (120 sq ft). We have one in our bedroom and it works great! And they are very energy efficient.

I mainly use it in my living room/tv/dining room, about 25x30. It is sort of one large room with half walls. It heats the entire area well.

400 watts is about right. it takes a while to come up to full temp but you can use the propane to speed up the process. I leave mine on full time. always have hot water.

It is being used in a room that is approx 250 square feet. The unit heats the entire room and keeps it warm with little trouble. I believe it is rated for 400 square feet.

Yes u should have no problems, its a lot less than a 900w heater or many other appliances u plug in

Yes -- the heat it generates is not dissimilar to a very small space heater. It's nice in my basement.

My wife has it on the floor and somewhat next to the bed. It's pretty easy to regulate temp. controls and the thermostat seems pretty accurate and sensitive. The thing about heat is that it rises. And the blowing air heats a bit locally, but goes straight up. Sometimes I find it more cost effective (for myself) to heat via conduction (heating blanket) or sitting next to something like the Sengoku panel heater which uses 150 watts.

Then again - I live in a 1860's Massachusetts house which is for the most part a heat sieve. :) My wife has it on the floor and somewhat next to the bed.

I thought mine worked well. The size of the room and its insulation make a big difference. The most effective for me was using it to heat our 12x14' master bedroom at night, and we kept the door to the rest of the house closed. With just the wall panel, the bedroom would get too warm and we'd have to turn off the heat during the night, which was great!

Nope. It's only 400 Watts, and even with the temp reading 71 degrees, I held my palm on the flat surface for a minute with no discomfort. I would NOT allow kids or pets close to it, and I'd be sure to keep the space in front and around it clear of any paper, fabric, anything flammable. It gives off a gentle, warm heat, and is not intended to be the sole source of heat.

I agree with the others. My Phenom 9850BE processor noticeably warms my room up under heavy load as it is. I expect that this one at 220 watts would definitely affect your heating/cooling expenses. Nothin' gives ya the WARM fuzzies like a fast multicore processor! :-)

I used a heat gun on low setting of 750watt, worked just fine, just be careful not to get too close, it can melt it.

I have a large living room, dining room, kitchen combo and another 10 x14 room off of the dining room. All connected. The heater does work well down into the 30s but it runs all the time. It doesn't put out a large amount of heat but it keeps the main living room cozy. It would have to be a smaller area to make it get too hot. It will not replace your furnace but it does help to keep the furnace from coming on as much. I had a 4 element heater but returned it right away and bought this product instead.

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.

VERY poor insulation is only one factor in understanding room "heat loss" so it is difficult to answer your question specifically. Any heater would be used to compensate for this "heat loss" and provide "enough heat". Given the size of the room, I would think you will see some limited improvement in comfort but it would be difficult for this OR any 1500W heater to sustain a high level of heat comfort IF you have significant heat loss.

I use it to heat 2 small rooms and it does a good job. So I'd say a medium size room. It's the best heater I've used and tried many before stumbling across this one.

This model dimplex at 2000 watts will give you 6824 btus. You ca. Heat a small bedroom 60sqft with 8ft ceilings with no problem. The insulation and the windows will effect this greatly if you have drafts.

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.
