Accordingly, what is dual fuel nest?
Dual fuel is when you have electric plus gas/propane/oil where the the heat pump needs to be turned off whenever the furnace is running. It is then called "Alt" heat. With electric heat strips it is "Aux" heat that runs at the same time and supplements the heat pump. Your system is single fuel.
One may also ask, is dual fuel heat pump worth it? Most dual fuel systems are set up so that electricity heats your home when the outdoor temperature is greater than 40 degrees. However, when temperatures edge closer to freezing, heat pumps are expensive to operate and you're better off using gas - hence, dual fuel heat. In theory, it gives you the best of both worlds.
