Converting to heat pump
« on: September 08, 2017, 06:28:57 PM »
I'm looking for information from anyone who has converted their AC to a heat pump. I have a Dometic 1500btu unit in our rig, and it works ok, but I'm interested in a unit that would both heat and cool. Anyone done this? If so, results?
TIA

If it's a ducted a/c, replacing the roof unit is pretty much plug & play.

The thermostat may be a problem if the RV does not already have wiring to the roof unit for heat controls. You may need to run a new control cable (has more wires for heat & chill modes). Your present thermostat may have no heat control at all, or may be wired direct to the LP furnace for heating mode.

   Relee52, Certainly no insult intended here, but you are aware that a heat pump does little to nothing below about about 35 F. Though many folks use them and are very happy.

LOL! Most RVers head south before they have to worry much about temps below 40.

     Gary, I guess we don't have this rv'ing thing figured out yet!   ;)

Thanks to all, our unit is ducted for AC in the ceiling and furnace in the floor. The thermostat is digital and wired to both, but like you point out likely to the AC AND propane furnace separately. I did know about the temp issue, but our plan is to stay in warmer climes so only taking the edge off in the AM. It's not a huge issue or an immediate conversion planned, just curiosity led to the post. We currently use our little fireplace and it does the trick for now.

If your RV has multiple cooling zones (separate zone for each a/c), you may already have suitable wiring to the zone controller. Sometimes the RV makers use the same wire bundle to the zone control for a/c only and heat pump. It's worth checking out when you have some spare time.
