Dual Fuel Systems Make Heating Even More Efficient. Several of the fuel systems we carry at Garoken Energy Co. Inc. in Beaverton boost your home’s efficiency more when they work in tandem with another Lennox® system than they by themselves. This is the case with for our dual fuel capacity gas furnaces and heat pumps, which can pair up to provide higher efficiency and greater comfort for you. Both systems work well on their own, 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 change between electric or gas heat depending on your preferred 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 increased demand for maximum MPG. You’ll be able to optimize your energy use, and you could lower your heating budget. Typically the electric heat is used until the outdoor temperatures reach 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. Learn more about the details of each of our gas furnaces and heat pumps here on our website, or give us a call at 503-374-1934. Garoken Energy Co. Inc. is located in Beaverton, so you can easily make an appointment to have us do an in-home consultation and show you how a dual fuel system could work for your home.
