Furnace question Challenger

Eager to know: does the furnace only run on propane? We r plugged in to our 50 amp at home and when we had company recently and put the heaters on, we discovered after 3-4 days that our propane was almost empty. I thought (Like with our last rig) the heaters ran off electric when we are plugged in to shore power and only use propane when we r going down the road or not hooked up, like overnight at a Walmart. Can anyone enlighten me? Am I mistaken? Thanks!

Nope, propane only. I use a small heater to keep the interior above freezing.

All RV furnaces use propane or diesel. They also require 12 VDC to control them. Some coaches have heat pump air conditioners that can also heat the coach and some air conditioners have heating elements to heat the coach.

Ok thank u. Our old class C forest river ran off of propane or the electric When plugged into shore power. We never had to fill up the propane over the winter. Don’t get it.

You might have had one of those goofily expensive CheapHeat systems.
It's $1,000 for the near equivalent of a $15 milk house heater that blows through your existing propane heater vents.

It's an easy add on if you think you'll offset a couple of thousand dollars of propane.

On the Challenger the furnace also heats the tanks and wet bay somewhat.
