Learn How Common Heating Systems Work

October 20, 2020

Cooler temperatures have arrived in DeSoto, MO, and frigid winter weather is on the way. Now is the time to make sure you have a heating system that’s ready to keep your home warm. Read on to learn how heating systems work so that you can make an informed choice about the best one for your comfort and budget needs.

Gas Furnace

Gas furnaces burn natural gas, the gas enters the combustion chamber and the pilot light ignites it. A heat exchanger passes the warm air through the air handler, where it’s filtered and pushed into the ducts. The waste products of the combustion process include carbon monoxide and other gases. These byproducts are passed through the heat exchanger into the furnace’s flue. Gas furnaces are up to 98% efficient at turning gas into heat.

Electric Furnace

Electric furnaces use resistance heating coils to generate heat. They’re like a big toaster oven. An air handler blows cool air from your home over those coils. The warmed air then enters your home’s ducts. Electric furnaces aren’t as energy efficient as gas furnaces. Some heat pumps have a built-in resistance heating coil to use for emergency heating when the outdoor temperature drops below 20 degrees Fahrenheit.

Heat Pump

During the colder months of the year, the heat pump uses a liquid refrigerant to absorb heat energy from the outdoor air. It can do this at temperatures as low as 20 degrees Fahrenheit. It transfers the heat into your home by way of a pressurized gas. The gas passes through the indoor coil, cool air from the air handler blows over the hot coil and the blower pushes the newly warmed air into your home’s ducts. The refrigerant is now cool, and it returns to the outdoor unit.
