If you endure harsh winters and are thinking of upgrading your heating system, a dual-fuel system is an excellent option. These utilize furnaces and heat pumps to provide efficient, cost-effective heating. Whether you’re making a full replacement or just want to add one of these components to your existing system, you’ll find everything you need to know on the topic below.

How Heat Pumps Work

Heat pumps draw warm air from one area and release it in another, like the opposite function of an air conditioner. As they circulate refrigerant, they pull existing warmth from the outdoor air. The substance passes through a single coil, evaporating and absorbing the trapped heat. It then passes to a second coil where it’s condensed. The captured heat is then released into a room via ductwork. This cycle is ongoing as long as the system is turned on, and it is an effective, affordable way to keep homes warm.

How Furnaces Work

Furnaces are forced-air systems that are fueled by electricity, natural gas, or propane. In gas systems, a burner lights a flame, which heats an exchanger and exhaust system. As cold air passes through, it warms to the desired temperature. The blower system then pushes this treated air into ductwork so it can circulate throughout the house. Cold air is then drawn into the furnace, and the process repeats.

How They Work Together

Heat pumps and furnaces work together in a dual-fuel system based on outdoor temperatures. In the mild cold, the heat pump warms the air, and the furnace’s blower circulates it throughout the home. Because the furnace’s burners aren’t lit, it only has to run at partial capacity. The same goes for the heat pump since it isn’t required to force treated air throughout the home.

Heat pumps are less effective when temperatures drop below freezing because there’s less warmth in outdoor air. At this point, the furnace burners ignite and heat the air to compensate. Together, they conserve energy while providing optimal heating.
