How Does the Furnace Heat My House?
The coolest months of the year have arrived in Fort Payne, AL. You might not spend much time thinking about your home’s heating system, especially if it’s working properly. If you’ve ever wondered just how a furnace works, this is an important question. Here’s what you need to know about how an electric furnace works and how a gas furnace works to keep your home comfortable throughout the winter season.
No matter whether you have a gas furnace or an electric furnace, it’s controlled by the thermostat. The thermostat is like the brain of the heating system. It detects the temperature of the air and signals when the heating system should turn on and when it can end the heating cycle.
How Electric Furnaces Work
Electric furnaces work like a big toaster. They have a series of wires. When electricity flows through the wires, they get hot. The air handler blows air across the resistance wires. The air gets hot, passes through a filter, and enters your home’s ductwork.
How Gas Furnaces Work
Gas furnaces have a gas supply valve that controls the flow of gas into the combustion chamber. Within the combustion chamber, an electric ignition, intermittent pilot, or pilot light ignites the gas. A metal heat exchanger absorbs the heat from the flame. Exhaust gases exit through the combustion chamber’s flue. Fresh air blown over the heat exchanger enters your home’s ductwork. The forced-air system blows the heated air through a filter. It then moves through the ducts and to each of your home’s rooms.
