Heat Pumps

Question: at what low temperature do heat pumps lose their effectiveness???? 45, 40, ????

I realize there is a point where they dont heat and furnace takes over.... just not sure what that is.....

When Im hooked up to elec in a campground, I use my ceramic heaters... (use CGs elec and save my propane)

I think the magic number is like 42 deg or so. But they flat out will not even come on at that temp or below. Little space heater is all you need.

Below 45 they're not much good; factor in the relative humidity and it's higher. Heat pumps are an a/c with a reversing
valve - so an a/c absorbs heat inside and releases it outside. Your heat pump is trying to absorb heat from outside to release inside. This might help understanding what we're asking the heat pump to do.

For what? Not to freeze to death in 20F ?

Most space heaters are 750W/1500W which is the same as the fireplace, if installed.

It will raise the temperature in the CENTER of the coach about 10-15F. So if it's 40 outside and you're happy in the 50's with 40's in the bedroom then that works. If you want to maintain high 60's inside or if it goes to 40 or below outside you'll need a lot more.

Of course you could keep the slides in and have lot less space to heat....
