Dual Fuel Systems Make Heating Even More Efficient. Many of the fuel systems we provide at Watts Electric & A/C Inc in Columbia increase your home’s efficiency more when they work in tandem 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 pair up to deliver higher efficiency and greater comfort for you. Both systems work well alone, 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 switch between electric or gas heat based 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 when there’s a higher demand for maximum MPG. You’ll be able to improve your energy use, and you could decrease your heating budget. 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.
