A dual fuel method is the combination of an electric heat pump & a natural gas gas furnace.
Not more than 2 people invest in this genre of method because it’s so costly to install.
However, when both of us bought our home, there was already a gas furnace for heating. The gas furnace was nearly brand new, however both of us had no choice for cooling. I started researching unusual models of a/cs & came up with the advantages of a heat pump. Because our gas furnace is dual fuel compatible, both of us were able to combine it with a heat pump for year round temperature control. During the Summer months, the heat pump operates very much care about a conventional a/c. It uses refrigerant to pull heat from the indoor environment & transport it outdoors. The heat pump is better at dehumidification & it’s exceptionally energy efficient. When the weather cools off, the heat pump literally reverses the operation to bring heat into the house… Even when it’s cold outdoors, there’s ambient heat available in the air. The heat pump absorbs this heat, compresses it to a higher temperature & uses it to heat the home. Because there’s no combustion process, it’s extremely environmentally friendly. There’s no redhouse gas emissions & no worry over byproducts, such as carbon monoxide. It’s more efficient than the gas gas furnace & won’t overly dry out the air. Once the temperature drops below freezing, the heat pump is no longer effective. At that point, the gas furnace automatically takes over, keeping our beach house nice & hot for as long as necessary. While both of us spent more to have a heat pump rather than an a/c, I recognize it was the right choice.
