Dual Fuel Systems Make Heating Even More Efficient. Many of the fuel systems we carry at Knoechel Heating Company in Zelienople improve your home’s efficiency more when they work in partnership with another Lennox® system than they by themselves. This is true for for our dual fuel capacity gas furnaces and heat pumps, which can be combined to provide higher efficiency and greater comfort for your home. Both systems operate efficiently by themselves, but when you marry the gas furnace and the heat pump, you’re taking advantage of both gas and electric fuel. The two systems will switch between electric or gas heat depending on your desired indoor air temperature and the operating efficiency of each unit. This works the same way as a hybrid car, alternating between electric power at low speed and gas power with demand for maximum MPG. You’ll be able to improve your energy use, and you could reduce your heating spend. Most times the electric heat is used until the outdoor temperatures fall to about 32 degrees Fahrenheit before switching to gas. Not only will you feel comfortable, but you can feel good about the efficiency of your dual fuel systems, too. Find more about the details of each of our gas furnaces and heat pumps here on our website, or give us a call at 724-452-6280. Knoechel Heating Company is located in Zelienople, so you can easily arrange an appointment to have us do an in-home consultation and show you how a dual fuel system could work for your home.
