Our Mobile Suites has the
RV Comfort Systems Cheap Heat system, which basically consists of electric strip heat added to the propane furnace to give the option to run the furnace either on electric or propane heat. Used in conjunction with the electric fireplace, the Cheap Heat system has kept us warm and toasty down into the low 30s with reserve capacity remaining as the furnace and fireplace were both still cycling.
To us, the advantages of the Cheap Heat system are:
1. Free heat if electricity is not being metered - we typically don't stay long enough at one place for metered electricity to be a problem.
2. No filling of propane cylinders.
3. Since the Cheap Heat system uses the existing furnace blower and ducting, it keeps the basement and plumbing system warm in sub-freezing temperatures.
The latter is the primary advantage over electric space heaters, which we've also used in the past.
