Geothermal power is a rapidly growing industry. But many homeowners feel hesitant about making the switch over to using the energy of the earth to provide even partial power to their house, such as investing in a geothermal heat pump. We understand the concern: geothermal systems require putting in a series of ground loops in trenches around the property. It sounds like an expensive process—and perhaps the cost isn’t worth it.
But the benefits of using a geothermal heat pump (a.k.a. a ground-source heat pump) are immense, and they include savings on home comfort all around the year. You can expect a geothermal heating and cooling system to pay for itself in only a few years—and then keep on working for years after that, helping your bank account no matter the season.
Why Geothermal Systems Are Energy-Savers
What is it about a geothermal heat pump that allows it to use less power than a standard air-source heat pump, a furnace, or air conditioner? The secret is a basic one: the steady availability of heat down in the ground. The earth radiates heat from its core. You won’t feel this on the surface, but only around ten feet down in the ground that heat creates a stable temperature region. This temperature is about the average annual temperature above ground, and it stays that way all the time—no matter what the daily temperature is above ground. It could be a scorching hundred degree day, and the ground temperature will still hover around 60°F or so.
The ground loops of a geothermal system use this stable heat to provide it with ample energy for heat exchange. An air-source heat pump must exhaust heat from inside a house to the outside, and it’s harder to do this efficiently when it’s extremely hot outside. It’s the reverse in winter, with the heat pump having to put in more work to draw heat from the colder air outside. A geothermal heat pump has no trouble in either condition: it can easily pump heat into the ground or draw it out.
How Much Does a Geothermal System Save?
It depends on the home, but the U.S. Department of Energy estimates a geothermal heat pump is four to six times more efficient than a standard heat pump. If you’re comparing the heating mode of a geothermal system to an electric furnace, the savings are even more immense. The payback period can be as short as three years depending on how much energy you use annually. Considering that the loops in a geothermal system can last more than fifty years, that’s a fantastic bargain.
Along with the savings, a geothermal system is reliable, requires few repairs, is easy to maintain, and is a benefit to the environment.
