If you want quiet, get an oil filled heater. They take up more space but do the job.
Otherwise, get the heater you like. As said, they are all about 1500 watts.
Even the cheap ones.

our 1500-watt fan heaters are whisper quiet and take up virtually no space.

Lots of opinions on what to buy ... but running an electrical heater on lower setting often creates more heat because they tend to shut off prematurely running on high. Two heaters run on lower settings on separate electrical outlets will often generate enough heat to keep the RV warm.

Personally I hate portable electric heaters. We installed a Cheap Heat electric add on unit to our gas furnace. Not cheap to buy, but heats the basement also, provides 1,800 watts on 30 amps, and 5,000 watts on 50 amp. We also have an electric fireplace heater that will work well in really cold weather.

750 watts keeps my TT warm but not my tanks. How are you warming your tanks?

The very reason the question was posted. Lots of opinions/suggestions!


For those of you using electric heaters, make sure you don't overload your circuit(s). I strongly suggest people inspect their AC panels . I found a loose neutral connection on the bus bar that was starting to overheat turning the white insulation brown. Caught it before it fried the bus bar! Don't want to find out the hard way you have a loose connection.

I stand corrected, thank you. I'll have to check them out.

My preference is for no one type.

If there is a frozen compartment--a radiant heater is best. I've been able to meld the ice on the seal.

If there is a cold floor--electric heated carpets are best.

If there is room in the bedroom, a pair of oil filled, one on each side of the bed, may be the most comfortable.

If size is a concern, then fan based ceramics work a charm.

I keep a 240 volt incandescent bulb fed with 110 volts, on a mechanical thermostat beside my water pump.

To heat 100% electrically, replace the cold air return grill on the furnace with a twindow fan. In my RV that keeps a small amount of warm cabin air circulating through the duct work for the furnace, preventing plumbing system freeze ups.

My peak wattage in the deep cold is 7700 watts, and the continuous load is 5.4 kwh.

I do use my autoformer to keep the voltage up, so I get the full number of watts from my various and sundry heaters.

I've boondocked at -37 c (-34 f).

Hi Lwiddis,

I replaced the furnace return air grill with this:

It pressurizes the duct work and keeps the plumbing from freezing up. It is controlled by a mechanical thermostat which is tucked against the outside wall inside the kitchen cabinets.

We have 2 of the small cheaper 1500W ceramic heaters that are common to Walmart etc. They are easy to store and you can run 2 on high (25A for both).


I second this. Unless it's really cold, you may need only one. I've used one in a 25' trailer and it would heat up the place really fast.
