15k AC w heat pump?

If a rig has the 15k AC with Heat Pump, does the heat also work off propane?

If not does that mean to run heat if not hooked up (boondocking), then generator has to run.

Thanks

Just like the AC...those run on 120v systems (Gen needed). Heat pumps are like running an AC backwards...kinda.

Your heat pump is electric and works through your AC unit. It will work fairly well when outside Temps are above 45 degrees. Your furnace is propane powered and will work as long as you have 12v power.

Yes a heat pump is an option on your ac unit. You should have a separate furnace that operates independently from your heat pump.

The heat from the heat pump runs off of electricity. It will heat only down to around 35° or so. Your furnace will work off of propane.

What Dometic offers for their AC units is not a true heat pump, it is a wire coil that is heated by running 110V electricity through it and the heat is forced into the room with a fan. I believe this option can be purchased for around $70.00 on Ebay and fits the 15K unit for sure that has the ceiling controls. There may be other options that I am not aware of.

The Dometic 15k is a true heat pump, not an A/C with a heat strip. The compressor runs in both A/C or heat pump operation, and it produces about the same BTU output either way.

The heat pump works well down to about 40 F. Between 40 and about 30 F it has to defrost periodically. Below about 30 F the thermostat will run the propane furnace even if the thermostat is set for heat pump.

Also, be aware that the propane furnace has small ducts to the water pump/filter compartment and to the sewer drain compartment. This heats them and the tanks. The heat pump does not heat those components.
