Dual Fuel Furnace Wiring

As long as the temperature is above 35 degrees f or so a heat pump can pull heat from the outside air for less than it costs to fire up the furnace.

Dual fuel furnace wiring.

Since a heat pump is more efficient than a gas furnace at higher temperatures the dual fuel system defaults to a heat pump on milder days. If it were always that simple you d be all in for dual fuel no matter what. Dual fuel systems heat pump with furnace dual transformer systems systems that have more than one r wire whole home humidifiers and dehumidifiers compatible with nest learning thermostat only. What makes this system so.

A dual fuel system may come in the form of a packaged unit or a split system with two energy sources. The dual fuel set up. About the c wire. As long as outdoor temperatures remain above the.

Heat pumps save energy because transferring heat is easier than making it. A dual fuel furnace takes on the problem with a hybrid approach that combines a heat pump and a backup gas fired heater. Natural gas is more efficient for bigger heating loads so the dual fuel system uses gas when temperatures get really low. Dual is better than one.

Dual fuel technology combines the cooling and heating performance that you get from a heat pump with the consistent heating capacity of a gas furnace. 2 nest thermostat can only support one of these systems at a time. The furnace kicks in for only the coldest months.
