But for heating you don't have to use electricity, you lose less energy burning propane for heat than if you burned propane to make electricity to deliver 100 miles away to turn back into heat. And there is always the option of wood burning which is common in northern areas and also renewable and cheap. Producing heat is 100% or more efficient, producing cold air is far less efficient.
- maxerickson 8y agoEven really nice furnaces lose some energy up the flue, so they are less than 100% efficient. They hit ~95%, which is really good, but it's less than 100%.
- sokoloff 8y agoHeat pumps can exceed 100% efficiency (as measured by heat moved into the building divided by energy input to the heat pump).
- maxerickson 8y agoIf we are being pedantic, they aren't furnaces with flues.
