Dual Fuel Systems Make Heating Even More Efficient. Many of the fuel systems we provide at Rapids Sheet Metal Works Inc in Wisconsin Rapids boost your home’s efficiency more when they work together with another Lennox® system than they do alone. This is the case with for our dual fuel capacity gas furnaces and heat pumps, which can be combined to offer higher efficiency and greater comfort for your family. Both systems are great by themselves, but when you combine the gas furnace and the heat pump, you’re taking advantage of both gas and electric fuel. The two systems will alternate between electric or gas heat in accordance with 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 hone your energy use, and you could decrease your heating spend. Usually 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.
