RV Comfort Systems, a Washington-based firm, has successfully engineered an electrical heating option, an add-on assembly for any RV propane furnace, so today’s RVer can choose propane or electricity to heat the interior of the coach.
Called the CheapHeat System, this unit is mounted directly downstream of the existing gas furnace and employs tungsten heating coils powered by 120 or 240 volts AC to provide the heat.
