What does dual fuel mean on Nest thermostat?
A dual fuel heating and cooling system is a combination of a heat pump for primary heating and cooling, and a furnace for a second and/or third stage of heating.
How does a dual stage thermostat work?
The furnace has two levels of heat output, high and low, when it is cold. Since the low setting is adequate to meet household heating demands 80% of the time, a two stage unit runs for longer periods.
What temperature does a dual fuel heat pump change over?
The heat pump and furnace are used in hot and cold temperatures, respectively. Depending on the circumstances, it can switch between the two to save time and energy in getting your home to the desired temperature.
What is a dual control thermostat?
A dual controller will allow you to control both an electric underfloor heating system and a heated towel rail from one controller.
Is dual fuel the same as auxiliary heat?
Electric heating elements are usually used in a heat pump auxiliary. W/Aux will use the heat from the compressor to get the temperature. The compressor in a heat pump can’t keep up with the temperature. The auxiliary heat is powered by fossil fuel.
What is the advantage of a two stage thermostat?
The two stage technology can be used to adjust heating output. Quiet operation and improved indoor air quality can be achieved by more consistent air flow.
How do I know if my furnace is dual stage?
