Dual Fuel Furnace Wiring

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.

Dual fuel furnace wiring.

Heat pumps save energy because transferring heat is easier than making it. Dual is better than one. 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. Heating with a dual fuel heat pump.

As long as outdoor temperatures remain above the. What makes this system so. 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. The furnace kicks in for only the coldest months.

About the c wire. A dual fuel furnace takes on the problem with a hybrid approach that combines a heat pump and a backup gas fired heater. 2 nest thermostat can only support one of these systems at a time. 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.

The electric heat pump and a gas furnace. The dual fuel set up. The common c wire doesn t control heating or cooling.
