Gas vs. Oil Furnaces

Determining whether a gas or oil furnace is right for your home depends on a number of important factors.

According to Energy Star, AFUE refers to the percentage of heat that is converted from the incoming fuel to space heat without being lost. When measuring the AFUE for furnaces the higher the rating the more efficient the rating is.

With the newer oil furnaces, they have AFUE ratings between 80% and 90% and with the gas furnaces having between 89% and 98%

Oil heat is generally more expensive than gas heat due to the U.S. having to import the oil whereas natural gas is produced in both the United States and Canada. With a gas furnace, they provide higher efficiency, maintenance is minimal and a gas furnace is connected directly to your utility company which means you do not have to worry about a storage tank. They are also a cleaner and quieter source of heat than oil furnaces.

Oil heat provides more heat per BTU due to an on-site storage tank. Oil furnaces tend to cost a bit less than gas furnaces, but they require more maintenance, a service contract, increase in fuel prices and provides lower efficiency.
