snowyegret52 ,, after you install a house battery, you will most likely be able to get the house furnace running. It has to have 12 volt power to operate and light! it will be much nicer that the unvented Mr buddy, heater!! those things use a lot of those little cylinders, and are not safe either, because they consume the air inside the MH also! You will be happy you got your furnace going, and do not have to worry about wake'ng up dead!!!!! Hahahaha!! the solar chargers will work good, as long as you have plenty of sunshine! Plus you can hook the tanks you bought to the rv tank and keep your self in propane that way, also you can fire up the water heater and take hot showers too!! And cook!!
