combo ac and heater replacement?

[steve sands]

Hey guys, I was wondering if they make a combination a/c and heater unit (all electric) to replace the a/c unit on top of my '72 globetrotter? Has anyone ever seen anything like that? Any help is appreciated.

Steve,

Dometic makes an AC/heat pump but it only works down to 40 degrees F. Then you heed a heat strip or a furnace.

The biggest drawback will be the lack of tank heat. The furnace blows hot air around the weather and holding tanks. Without the heat they will freeze if you are camping in freezing weather.

It all depends on when and what the weather is when you camp to say if it is enough to have a heat pump only.

Steve Sands - First of all, welcome to the Forum!

Most of the recent conventional A/C's installed also have a resistive heat strip element.

In my opinion, they are mostly worthless, however, with time, it will do some good. I ran a test on mine, the heat strip raised the exiting air by about 10 degrees F. It would take a LONG time for the heat strip alone to warm a cold RV.

But it is better than nothing.

The Dometic heat pump works well and is a good feature. You do need a furnace to keep your feet warm on occasion and to keep your plumbing from freezing while camping when it's in the twenties.
