Heat pump
The Coleman air conditioners in my Phaeton have a heat pump feature. I know that home heat pumps have heat strips that kick in at somewhere around 40 * F. Do the Rv heat pumps also have heat strips? It's been in the low 40's here the past two nights, and so far we are staying comfortable.

Check on your thermostat control for Electric heat switch. Our 2014 36LA has two Coleman Air Conditioners, but only the front one has the electric heat option. Works great, except make sure RV Parks have min 30Amp pedestals. Don't run on 15Amp. Too much load.

They both have the electric heat switch. I'm on 50 amps. Just wondering how cold it can get and the heat pumps still work.

The Coleman heat pumps do NOT have auxiliary electric heat strips. Mine work well down to 40 degrees and provide some heat down to around 36.
By the way, whether or not a home heat pump also has electric heat strips depends on region and model of heat pump. Here in Florida that feature would be rare, but in more northern climes some of them may have that extra capability s that the house doesn't need a furnace as well. RVs have an alternate heating source, so strips are not needed. Besides, the power (amps) to operate both the pump and an electric heat strip is simply not available in most cases.

RV Heat pumps do not have electric strip heaters. They work down into the 40s, but lose efficiency as it gets colder. They usually don't work in the 30s. At that point, your gas furnace should kick in automatically. If not, then switch to gas heat.

That is what I suspected. It was about 42 here this morning and the pumps worked fine so far. Not going to get any colder for the next week or two according to the long range forecast. I only have about a quarter tank of propane and don't want to use it if I don't have to. We have two furnaces, and I suspect they can blow thru some propane pretty quickly.

I don't believe Coleman has that option but domestic does.

My Coleman front heat pump works fine to the low 40s, but once it starts getting much colder it just does nothing heat wise, and just starts to make noise..... It does not kick over to gas unless you get the 5 degree temp. differential.
Early this morning (frost on the cars today), heard the heat pump "not happy" noise, got up and manually switched over to gas heater.......
Seems like it has always worked this way, but I need to recheck the manual to see if it is supposed to kick over to gas at a set outside temp point, so that it doesn't just run on and on while making a racket, until it hits that 5 degree diff. and kicks over to gas automatically.
Regards

The Coleman Mach 8 Heat Pump spec shows an optional Heat Strip.

Well I don't use the heat pumps because if they go out it will be hundreds to a thousand to work on or replace. A $20-30 electric space heater is just as efficient. I keep them on top of cabinets or the ceramic floor.

Well ... OK ... but, with the exception of the reversing valve, your air conditioner is the heat pump. That's kinda' like not using your air conditioners because you think they might fail. I do agree that inexpensive ceramic heaters work pretty well.

Ditto. It makes a racket and sometimes trips the breaker. That 5 point degree is what causes problems. I wish these had an option for outdoor temp set point. Sometimes my heatpump will try and run all night without tripping the propane furnace. If the temps are in the 50's or 60's, these things are the cats meow but below that, forget it. Problem is thermostat and not the heat pump.

I had to use mine last night as the gas furnace quit working. The noise is really irritating. Is it just me or are these just typically noisy?
