car heater to heat house?? Hi everyone. So i had a brain wave and thought id put it out there for help or advice. I have just moved into a new house and thought id start looking into heating for the upcomming winter. I thought about buying a new 19 kilowatt wood burner to heat the living area of the house and to heat the downstairs bedrooms i thought about using a wetback on the wood burner to circulate hot water through a copper pipe to the bedrooms and to pump the hot water through a car heater in each room so the 12 volt fan would blow hot air into the rooms and thus work better than a normal hot water radiator...............So what do you think?/?
