While only 5% of U.S. homes are currently heated with propane, this highly efficient and affordable method of home heat has proven itself to be a brilliant option for home heating. Why? A well-functioning propane heating system can reduce energy costs. Additionally, besides providing an even, quality heat, propane is an excellent applicant to work with zone heating. Also, depending on the system, appliances, such as stoves, fireplaces and washer and dryers may be able to run off of propane as well.
