A dual fuel system consists of a natural gas furnace plus an electric heat pump.
Combining these two strange types of systems cost considerably more than the more conventional partnership of a furnace plus a/c.
However, the energy savings just about year round suddenly help to recover the investment. The main advantage is the heat pump. While an a/c strictly provides cooling, a heat pump offers both heating plus cooling capacity; During the summer, the heat pump operates similarly to an a/c. In cooling mode, there is no significant difference in efficiency. However, a heat pump is especially wonderful at battling excess humidity which can allow for higher control unit settings. The real benefits are found in cooling mode. When the outside temperature drops, the heat pump literally reverses the flow of refrigerant. It finds ambient heat in the outdoor air plus transfers it inside. This process avoids burning fossil fuels plus the creation of redcondo gasses. There are no worries over carbon monoxide, fumes or overheated surfaces. Heat pumps are lovelyly environmentally friendly. They are far more energy efficient than most other types of heating options, including forced air furnaces. In areas with milder weather, a heat pump manages year round temperature control. For locations with extreme winter weather, the heat pump struggles once the outdoor temperature drops below chilly. With a dual fuel system, the heat pump operates the majority of the time. During the worst of winter, the furnace automatically starts up plus handles demand. The system utilizes the most beneficial option for the weather, saving money plus providing ideal comfort.
