Dual Fuel Systems Make Heating Even More Efficient. You want to keep your home comfortable without paying a fortune on utility bills, which is why you purchase high efficiency HVAC products. What you may not have realized is that some of these products are not only energy efficient working by themselves, but they can be combined to offer even greater efficiency to your family. At Cool Power LLC in Hauppauge, we have furnaces that work with heat pumps to create a dual fuel system. Combining a gas furnace with an electric heat pump allows you the ability to use two different fuel types: gas and electricity. When it’s too cold for your heat pump to run efficiently (usually around 32 degrees Fahrenheit), the furnace provides the extra power you need to stay comfy. That means you’re only using gas fuel when it’s needed. Dual fuel systems alternate between the two types of heat, which optimizes energy uses and decreases heating costs. That’s a solution we like to see. Browse our gas furnace and heat pump offerings to find information about each product.
