Does anyone have any feedback on how this works as a heater, how well does it heat at lower exterior temperatures, etc.?

It will heat. However, heat pumps lose their ability to heat as the outside air temp goes down. I live in southern California so it will work fine here, Minnesota not so good.

We love ours. It heats the area well. We keep it between 1&2 most of the time keeping our heat at about 70 degrees. We love in northern Maine where temps have been -20 and up to -40 on a pretty regular basis and it has been extremely reliable. I haven't let the temperature get down to 45 to test that theory.

Does this do well in small rooms with absolutely no heat during a Midwest winter? Or is this generally purchased to supplement other types of heat? Our little cabin has 2 rooms approx 15x15 ft. Outside temps are likely to be below freezing for the majority of 2-3 months or so. Thanks!

Michael, I have unfortunatly purchaed 2 of these heaters. One serviced for 3 seasons and it will not work now. the other developed the same problem in 4 months of regular use. I do not think they will make 140 degrees at any rate.I suggest you up size to another unit to met your needs, cheaper is not always better.The good news is I can work on this type of heater and have positive communication with the Marey tech. support for parts.Ric

The control isn't calibrated in temperature, only 1 - 10. The temperature it holds at any given setting will depend on several factors like outside temperature, leakage rate of any air infiltration into your space, starting temperature, thermal mass of the objects in your space, etc. I will say that for such a little heater, it ROCKS. I use it in my double car, insulated garage (no cars inside, only tools & stuff). This morning it was around 5F outside (30 in the garage) and it took about 20 minutes to heat the entire space to a tolerable 60 degrees. When the space gets to a temperature I like, I just turn down the control knob until it just shuts off and it'll more or less hold at about that temp. It has a rattle that I need to find and fix but overall I'm very happy with this heater. I'd considered a gas forced air unit but thought I'd try this before I went to all the trouble and am glad I did.

I purchased this heater about a year ago after much debate. I have been very pleased with it even on the days of -20 degrees Fahrenheit here in South Dakota. Did make one slight modification that has helped greatly. I bypassed the turn dial heat control and ran it to a thermostat. Very inexpensive modification and well worth it. I have an oversized double garage with 10' ceilings. Hope this helps.

The thermostat works like many in other such units: it will allow the ambient temperature to drop a degree or two below the set temperature before it cuts in and it will exceed the set temperature by the same degree or two before it cuts out. It's not a highly sophisticated unit--it's just a space heater, after all--but I have been very satisfied with its performance. I purchased it for use it in a fairly small space and it's just perfect.

to some point, how cold does it get out side? I had it in a room 12x24 and it ran all the time and never got above 0 c, it was -20 outside

I found that the unit is totally unreliable, the heater will not hold its temp,I seen up to an 8 degree variation and lost 2 clutches..I stopped using it..good luck!

I haven't had that experience. I'm on my second one and it keeps my shed (14x20) a nice 40-50 degrees even in 0 deg temps. I have a ceiling fan in the middle of the shed to disburse the heat downward since I have kennel walls. I've been very happy with the little heater.

I would not recommend that because a) it does not have any way to take in fresh outside air, meaning you would have negative pressure in your house and would be using your breathing air for combustion, b) it would not distribute heat throughout the house...you'd need ductwork, and c) it's pretty loud for inside a house. Not bad for a garage, but not great for a house. I think there must be better ways to heat a small house, including electric radiant heaters. You could buy several for the cost of one of these. Just my opinion.

Yes this heat works great under any condition. The outside temp has no effect. And yes u can use it inside but you would have to vent it outside

I think it kicks out pretty good heat at high. The rocks take sometime to get hot and red, but they do get there. Probalby wouldnt be as hot as the tall heaters, but it would be nicer. Very impressed with unit.

How did the two heaters work out? I'd imagine it to work well, depends on total square footage, yet Im not too sure how it will match up against two 1500 watt heaters.The thing I did like about this heater is that it doesn't dry out the air, and also has temp settings. If the area is a medium space, you should be fine.

I used it in my garage and the heater worked very well. It does say on the unit that it should only be used for backup heat. But it kept the temperature 70 degrees in my garage.

Not to sound condescending but if you don't have the "HEAT" function turned on the unit will not heat up. If it is still set to FAN or AC it will allow you to set it for 90 but it won't heat (and mine only goes to 80??) Additionally, if it is VERY cold (like 20s or below) the unit will not heat, it acts like a heat pump and the amount of heat goes down as the temps drop below 32 degrees. I only use mine to heat from about 30-55 degrees which covers about 90% of the time here in Alabama. During REALLY cold spells we cover the unit and use this DeLonghi TRD0715T Safeheat 1500W Portable Oil-Filled Radiator with Vertical Thermal Tunnels which we purchased here at Amazon and have used it for many years.

On the second question, I can tell you with certainty that it will not work as a heater unless the input air is 45 F or higher because of the physics behind its design. For heat on a cold day, you will have to carefully select another safe solution. (I guess the heat feature was designed for breezy evenings in southern Florida.) I had planned to use it to keep the attic warm in winter but I was disappointed by that lack of real merit as a heater. Off hand, I do not know the answer to the first question without referring to the instructions which aren't at hand just at this moment.
