Addning heat strips to heat pump AC units

I have two ac/heat pumps, both same models on my 07 Discovery. The units are running w/o issue BUT I'd like to save my propane & install some heat strips.

Has anybody done this before? I have located heat stips for Coleman AC units but I need to check & see of the controller had the plug (2 pin) for the heat strips.

Roof units are model 8534C8797. Both function 100% but when the temps are down below 40 the heat pums don't function well.

I found this Heat strip;

  • Heat strip will supplement the Heat pump between 30 - 40 deg F. Anything below that & it will have to be Gas furnace or, in my case a small ceramic heater in the coach set at 40 deg and a 60W bulb in the heated basement. When I'm done for the winter (in about two weeks) I'll remove the perishables & winterize.
    Deb & I are trying some winter camping this year.

    Last weekend we stayed in an RV campground with just 30amp service. Woke up to about 35 degree temps & the heat pumps where not putting out much, if any heat.

    The heat strips are about 40/pop & takes about 10 minutes to install. I'm not expecting to heat the coach with just the heat strips.


    Thanks

    I'm not planning to use heat stips all winter long. I do relize that it will NOT keep the rig warm below freezing. It's just late fall when I'll be using it.

    Spent some time last night reading & found that the AC units I have DO have the option available for heat strips. I found two at $40/strip.

    My older 93 Pace Arrow Diesel has two older rooftop units with heat strips as well.

    Thanks for all the information.


    This we understand. But, WHY, Install the Heat Strips when you have the Heat Pump to do the warming when above freezing??????? Doug
    x2. Didn't op say he had two heat pumps? I have one in my 37' motorhome and it kept it nice and warm down in to the high 30's.
  • EACH Heat Strip (5600btu/hi fan) pulls a TOTAL of 13.5 to 15.5 amps depending on which model RVP AC or HP you install it on. you will drop 1 amp for med or lo fan speed. So, it does NOT matter what shore power you are on, the Heat Strips are as much of a Amp hog as the HP mode. Doug
  • Have you looked at cheap heat, heating element installed in the gas furnace?
  • Hi,

    Nothing cheap about the cheap heat system. I heat 100% electrically. Low last night was 10 F (-12 C)
