On a cold winter’s day in Rochester, Minnesota, there is nothing quite as enjoyable as watching the snow fall from the warmth of your home. Understanding the basics of how your furnace works can help ensure your comfort and keep the equipment functioning as it should for many years.
Comprehending the Heating Cycle
Your furnace warms your home by repeatedly going through a heating cycle. It starts when propane or natural gas is ignited. The heat from the flames causes the heat exchanger to get hot. The exhaust produced from the combustion leaves your home through the flue.
The heat exchanger heats the fresh air that is pulled into the furnace. The blower pushes the heated air into your home’s ductwork. Your ducts distribute the warmed air to various rooms in your home. As warm air enters the different rooms, colder, heavier air is sucked back into the furnace through the return ducts. The process then begins again.
Gas Furnace Basics
The components in your furnace work in harmony to keep your home warm. Various furnace models are available, so some pieces of technology may vary as well, but the essential functions are the same for all fuel-based furnaces.
Your thermostat tells the control board in the furnace to start the heating cycle. A fan sucks air into the system to be warmed by the heat exchanger. This is accomplished because the control board has also told the burners to ignite the gas and create combustion. The same fan pushes the warm air out.
The burners are a series of tubes that become filled with gas, which is burned. You also have a flame sensor, a gas valve and other safeguards that work together to keep your furnace performing this function safely.
Your heat exchanger is a series of metal tubes that warm the air inside them once they’re heated by the burners. At the same time the blower is pushing that heated air through your home’s ductwork, the flue is getting rid of any fumes created by the combustion process.
