Can Geothermal Heating Work for My House?

geothermal-heat-pump-diagramIf you’re looking to make a change in your home heating for the coming season, you may not have “geothermal” on your list. Maybe it hadn’t occurred to you that it’s an option, or perhaps you thought it was something out of reach for your house. 

We understand why many homeowners think geothermal isn’t something that could work for their comfort. It seems like such a big change that people back away from it. But it isn’t as major a change as people think. If you’ve wondered if geothermal heating can work for your home, we’d like to help answer that question. You may be surprised to find the answer is “yes.”

Geothermal Heating Is Like Standard Forced-Air Heating

Although the way a geothermal system retrieves heat to bring it inside the house is different from the way furnaces and standard heat pumps work, the way the heat is distributed isn’t. You’ll still use a standard set of ducts, and a blower fan will send heat from a cabinet through the ductwork to the rooms.

That’s the way other forced-heating systems work: an air handler sends heated air around the house. If your home already uses a heat pump or central furnace, you won’t have to make many adjustments to the indoor system you already have in place in order to enjoy geothermal heating. 

How Geothermal Systems Provide Heat

So what sets a geothermal system aside from standard forced-air heating if the indoor sections are similar? The source of the heat. An electric furnace generates heat through electrical resistance, while a standard heat pump moves heat from the outside air indoors where it releases it.

A geothermal system is a type of heat pump, but rather than draw on heat from the outside iar, it pulls heat from underground. A set of loops with a water and antifreeze mixt are buried beneath the frostline of the property, where they access a steady amount of heat from the earth. (No matter how cold it gets topside, the temperature down 10 feet and below remains stable around 45°F). The loops draw this heat into the house, transfer it to the refrigerant in the indoor heat pump, and then release the heat through the indoor coils. 

And remember, since a geothermal system is a heat pump, it can also work to cool a house during the summer. 

Does My House Have the Space for Geothermal?

This is the big question people have when it comes to installing a geothermal heat pump. The loops must be buried under the property, which takes up space.

Fortunately, different loop configurations make it easier for installers to find ways to place geothermal loops onto smaller properties. We handle many types of Wake Forest, NC heating installations, including geothermal heat pumps, and you can trust our experts to tell you if going with geothermal is feasible for your home and how long it will take for the geothermal system to pay back its installation cost with its energy savings.
