How well does it work as a heater? I'm looking primarily for a portable heat pump, but also A/C. Is this reasonable to use as a heater?

The "heater" is not described in BTUs as the AC is. Other units I have been looking at do use BTUs for the heater. I would need to know how this heater works and it's effectivness in a 400 ft2 room

The Whynter ARC-12SDH utilizes a heat pump for heating and has a full thermostatic control with temperatures between 61°F - 89°F. Please feel free to contact us at customer.service@whynter.com.

I have not relied on this to heat a room. It may very well heat a room, but I have not asked it to do this. I have used it more as a "spot" heater. That is, I position it a couple of feet away from where I am sitting, while reading or such, and find it keeps me very comfy. I am very satisfied with this purchase for the use I have described.

Absolutely! This heater is small, but it does work as described. The main thing is to make sure the outlet that you plug into is rated a minimum of 15 amps. Any less and it will not work. This is where a lot of the low ratings are coming from, imo. I have had this as a supplement to my regular heat as my heater core is clogged and I can not clean it out at this time during the winter. My unit has been working great for the last 1 1/2 months that I have owned it. I installed a dedicated outlet for mine connected directly to the battery rated at 20 amps with # 12 awg wire and have had no problems. If anyone needs help and a list of materials to install a dedicated outlet, I will be glad to assist. Absolutely! This heater is small, but it does work as described.

I have a heat only system too with window A/C units. It works fine controlling just the heat. Great thermostat have had no problems.

We live in Florida so it's perfect to heat up a room your in. Way cheaper than my electric bill if I ran the heat. P.S. it does get cold here...

It generates a bit of heat yes, but I've never had it overheat. Max ambient temp I used it in was I think 32C.

The documentation states that it should not be used as a heat source if the temperature is below 40 degrees. Mine will not heat effectively in very cold conditions. However; it will perform well in the 50 degree range and above. I suggest a call to the manufacture.

Because this machine generates heat (warm air), it probably works in winter only. I do not recommend this to be used in Florida during summer. It works against your A/C. Also, if you are sensitive to noise, this one makes switch noise between dehumidifying and just blowing air, it may wake you up in a bedroom. I hope this helps. Thanks.

Yes, this device is made fora heat pump or central air, by just flipping a switch when installing. Very intuitive , you will have no issues.

In our opinion, it works well as an additional heating unit in a hard to heat space. We use it in our playroom which is a large room that is an addition to our house that has only 2 vents providing heat from our house unit. It can raise the temperature several degrees in our large space pretty quickly but would not be adequate as the only heating source.

I use it to heat and cool a 14' by 17' den and it does the job. I don't think you need to worry about it being too much. A lot will depend on how cold/hot the room is in comparison to where the thermostat is located, and also the temperature of the heated or cooled air. I have a heat pump so the air is never real hot and it works out fine. A gas furnace might warm up a little faster but you also have a lot more area to heat.

I can confirm CoralHind's answer. I use it with a generator and portable A/C in my van. The A/C unit would not work without it because my generator frequency was not stable.

I would like to give you some input but just brought it out to the shop to test. i had purchased other pumps that claim to be high temp but failed within hours and in cold water. My desirefor this pump is to circulate water or coolent exchange for winter water heating and space heating. Looking at this pump with x-ray eyes has determined that the configuration is much like oil pumps in the industry. First seen it on the old VW's. Looks reliable so long as the motor is bearinged and not bushinged. Mark

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.

In heat mode, mine vents cold air to the outside through the same hose as it blows cold air when in air conditioning mode. In heat mode mine blows hot air out the vents in the top. It is heat pump, so it won't work if it is too cold. If you vent air in from the outside and it is 45 degrees or less out, then the heater won't work. Disconnect you air intake hose so it is using the room air and it should work. I'm not a technician, but this is my understanding.

Where I used mine....I didn't have an electric bill. But....the efficiency of these is lower than a standard window unit. You are using interior air to cool the condensor, then pumping that now hot air...outside. But if you're pumping air out, it has to come in from somewhere. That somewhere is outside hot air. I would only recommend a portable unit like this if it is your only and last choice. The unit itself works fine, just poor efficiency.

heat pump do not work well or at all at temps much below 32F when the temps get down to around 25f they really do not work at all most house heat pumps have electric heat coils built into them just for this problem I do not think these mini system have that setup
