Operating Furnace On My Class A RV

My wife and I are newbies to the RV world and we are heading south at the end of October for an extended 6 month trip. My main control panel states that the furnace has both an LP mode/ electric. Does this mean that if I am hooked up to shore power I can run the furnace on electric? This would certainly save on LP usage if possible. Thanks for any inputs.

Are you sure it is the furnace and not the hot water heater? Some like my hot water heater as both options you can run them on electric or propane.

Could you let us know what make/model RV you have? That would be helpful.

Operating The Furnace On My Class A

Sorry. I have a 2006 National Dolphin 36 foot gas model with the Ford V-10. I have a separate switch on my main panel for my hot water heater.

Here is what I think you are describing/asking. On my 2009 I have LP furnaces and I have heat pumps on the air conditioning units.

I think you are looking at a thermostat and it shows a selection of gas or electric.

If that is where you are seeing LP and electric in the heat mode, then if you choose electric the thermostat will turn on the heat pumps when the temp calls for heat. If you choose gas, then the floor furnaces (LP) will come on.

If you do have electric heat pump/ac units, then they will produce heat until around 42 degrees outside at which point the LP furnace will eventually kick in because the electric can't warm the coach to the set point.

Operating The Furnace On My Class A

Thank you. Yes, I am looking at my thermostat with the two options and your explanation of the possible heat pumps makes sense. I guess the only way to find out for sure is to use it. I will also check the manual when I pull the rig out of storage.

I suspect the electric side is heat strips in the AC rather than heat pumps. Works about the same. Test it in the drive way. Set the system to electric heat and run the thermostat up and find out if the AC comes on with warm air rather than the propane furnace.

We have a 1200 watt space heater that pretty much does the job of keeping the coach warm down to about 35 degrees when I switch over to propane to also keep the fresh water pump/tank above freezing.

We have 2 AC/Heat pump units and an LP furnace. Our thermostat is like what you have described. We can run the furnace only using LP. If we switch to electric heat several things can happen, depending the current temp and the temp setting on the thermostat.

If the current temp is, I believe 5 degrees, below set temp then both heat pumps and the LP furnace will come on. Once the temp reaches the thermostat setting it will try to maintain the temp using one heat pump. If that's not enough it will use 2 heat pumps. If that's not enough to maintain temp the LP furnace will be used.

I mention this so you're not surprised if you turn on electric heat and the furnace also comes on.
