    Heat Energy Efficiency: Propane delivers more than twice the energy of natural gas as measured in BTUs (British Thermal Unit), which means a propane furnace will be a more efficient source of heat. To put it differently, a propane furnace will produce the same amount of heat using half the amount of fuel. This is an important factor to consider when the price of natural gas per unit is usually a bit more than propane.
