Furnaces on an average can have highest AFUE rate of 95%. So no matter even if you buy a high efficiency furnace, you can expect that 5% of energy will go into waste. Electric furnace have a higher efficiency rate, as it does not give out exhaust gases unlike a fuel furnace does. But prices of electricity are spiralling each day.
