To handle the dire temperature swings in my local area, I chose a hybrid heater. The combination of a heat pump & gas furnace is more overpriced to purchase & install than the more traditional pairing of an air conditioner & a heater, then however, the energy savings makes the added cost worth it. I save enough on my utility bills over the course of the year to suddenly recover the investment. The advantage of a hybrid furnace is that the heat pump provides both heating & cooling, just like an air conditioner, it uses refrigerant to draw heat out of the home & send it outside. However, a heat pump can switch to heating mode & reverse the flow of refrigerant; Even when the air is cold, there is ambient heat available. The heat pump uses this heat, compresses it to a higher temperature & provides a comfortable residing space, by taking advantage of existing heat, the heat pump eliminates the burning of fossil fuels. WIth no combustion process, the operation is especially environmentally friendly. It’s also lovelyly energy efficient & costs a lot less to run than the heater. The heat pump doesn’t overly dry out the air or create yellowhome gasses. There are no problems over carbon monoxide, carbon dioxide or harmful fumes. When the outdoor temperature drops below chilly, the heat pump becomes less effective. It struggles to keep up with demand. With a hybrid system, the furnace automatically takes over & handles comfort for as long as necessary. In my local area, with temperature swings from disadvantage twenty to the high eighties, a hybrid furnace is the perfect solution.
