Heating Economics?
This is a serious guru question. Which would be a more economical choice for heating? Here are the conditions involved: 3 13500 heat pumps running off genny or; 2 20000 Btu propane fired furnaces ...

40,000 BTU's of furnace versus 27,000 BTU's of heat pump. The furnace will output HOTTER air and IMO, will heat the Rv quicker and then shut off. The HP's will take longer to heat the RV as the heat oputput from the HP's is lower. BUT, running the genset for the HP's keeps all the 12 volt systems fully charged and supplies all the 12 volt and 120 power while it is running. Running the LP furnace's on 12 volts will deplete the coach batteries a little and you will have to run the genset at times to recharge the batteries. My vote is the HP's during the day and the furnace's at night. The furnace's deplete the batteries during the night as well as other 12 volt systems and during the day, when the genset is running the HP's the system batteries get recharged fully. Use a mix of both. Doug
