Dual Fuel Systems Make Heating Even More Efficient. Several of the fuel systems we carry at Effective Service Group, LLC. in East Hanover increase your home’s efficiency more when they work in tandem with another Lennox® system than they do alone. The same is true for for our dual fuel capacity gas furnaces and heat pumps, which can work together to deliver higher efficiency and greater comfort for your home. 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 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 hone your energy use, and you could reduce 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.
