Gas Fired Furnace Heating Systems
Gas Furnace Advantages
- Natural gas is an inexpensive natural resource of energy.
- You don’t have to remember to get your tank refilled.
- Natural gas helps protect our environment.
Gas Furnaces efficiency has improved over the years with use of cleaner, safer equipment, and standards. Energy Star standards have significantly changed how manufacturers engineer air conditioning and heating equipment, making them more efficient than ever before! Gas Furnaces are up to 98% efficient on the Annual Fuel Utilization Efficiency rating scale.
How It Works:
The typical gas furnace is fueled by either liquid propane or natural gas. In modern gas furnaces, there are two intake valves that bring air into the system. A draft inducer fan motor sends air into the burner assembly to supply oxygen for the fuel that is to be ignited by a spark igniter.
The igniter ignites the gas, and oxygen keeps it burning at a high temperature. The gas burner heats a set of pipes called a heat exchanger. The heat exchanger heats water, which is piped to radiators throughout the house, where it radiates the heat into the room. The carbon monoxide and other fumes is expelled through the flue pipe leading outside of the home as an exhaust.
