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;

  • Hi,

    If he has two that would produce 10,000 BTU's. I don't call that "a little heat". That said, last winter during the deep cold I was using about 19,000 btu's of electric heat.

    The heat strips in the A/C unit actually produce very little heat. You would be much better off just buying the little ceramic heater cubes for about $20.

  • Heat Strips only have 5600 btu's of heat EACH. You HP's have the full 13.5 or 15k rating. BUT in sub 35 degree temp, the Heat Strips will not do anything to heat the RV. Heat Strips were never designed to HEAT the RV. They were designed to take the chill off the morning or evening air. Doug
  • When it's cold out & we are connected to 30 apms or more it would be nice to save the propane! It's been working all summer till the temops start dropping!

    Sunday morning it was about 35 deg. and the heat pums where not putting out any heat.

    I'll report back on my findings. "IF" I find the proper plug.

    Hmmmm at the bottom of the link...
    This will NOT work with MACH 8 Air compressors or MACH8 Heat Pumps. Use Coleman 47233-4551. Don't think my units are reffed to as MACH 8..

    More searching....
  • I put a heat strip in mine and it didn't satisfy me. the AC moves so much air that the heat strip did not feel like it was putting out any heat.
  • I've thought about doing this as well, figure why not run AC heat when I'm in a campsite with electricity.

    Haven't done it, but have thought about it. :)
