A dual fuel system is an electric heat pump paired with a gas furnace to assist in heating during colder months. A standard heat pump will operate at temperatures down to 35 degrees F, then will switch to auxiliary electric heat strips. This can lead to expensive electric bills if the sub-freezing temperatures persist for an extended amount of time. In a duel fuel system, once the temperature gets down around freezing, an outdoor temperature sensor will signal the indoor thermostat controller and the gas fired unit comes on and heats the home, instead of the auxiliary electric heat. Once the outdoor temperature rises above the balance point, the gas furnace will shut off, and the heat pump will take over again.
BENEFITS OF A DUAL FUEL SYSTEM
Dual fuel systems are much more efficient than standard heat pumps or forced air units. By getting “the best of both worlds”, the system saves on energy costs by using fuel to heat as opposed to electricity. There may also be energy savings tax credits for the system upgrade depending on the area. A dual fuel system may cost slightly more to install, but the savings in energy will more than make up for it throughout the lifetime of the system.
Dual fuel systems can also be in a single stage, two stage, variable speed, and modulating configuration. By having a higher efficiency furnace in the system, the unit can cool and warm the house to specific needs by controlling blower speeds, and/or burner stages. This allows for greater efficiency and maximum energy savings. Dual fuel systems are just another great option to effectively and efficiently heat or cool a home.
When installing a dual fuel system in the home, natural gas piping or propane must be available. Also, adequate ductwork must fit the indoor unit (furnace). These units work best in moderate summer climates that have very frigid winters.
