Dual Fuel Furnace Wiring

What makes this system so.

Dual fuel furnace wiring. The electric heat pump and a gas furnace. Heating with a dual fuel heat pump. As long as outdoor temperatures remain above the. 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.

Natural gas is more efficient for bigger heating loads so the dual fuel system uses gas when temperatures get really low. 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 dual fuel set up. The furnace kicks in for only the coldest months.

2 nest thermostat can only support one of these systems at a time. A dual fuel system may come in the form of a packaged unit or a split system with two energy sources. A dual fuel furnace takes on the problem with a hybrid approach that combines a heat pump and a backup gas fired heater. Dual is better than one.

If it were always that simple you d be all in for dual fuel no matter what. The common c wire doesn t control heating or cooling. 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.
