Answer: In terms of efficiency it is the electric furnaces that win. They nearly use 100 percent of the electricity to convert it into heat. In combustion furnaces there is always loss of energy when gas or oil is being converted into heat. This loss can range from 5 percent to 30 percent. When buying a furnace always check out its efficiency ratio. This is found on the furnace labelling.
