The How and Why of a Geothermal Heat Pump

What the great majority of people say they love most of all about a geothermal heating and cooling system is that it has so little in the way of moving parts. There’s just that much less that can fall apart– that much less needing maintenance. And that alone goes far in cutting the overall energy costs of Ebensburg homeowners who’ve gone geothermal.

 

That said, there are some moving parts in the system. the majority of them are found in its most conspicuous component, too: the geothermal heat pump.

This is the engine that drives the system. Its task is to transfer heat. And it transfers heat either from the ground into your house or from your house into the ground, depending on the season30. Thus, it’s a furnace and an air conditioner united in one unobtrusive package.

How the heat pump transfers heat is with water or an antifreeze solution. This liquid circulates through pipe loops installed underground and linked to the heat pump, which is positioned above ground. During heating season the liquid draws heat from the ground, the heat pump draws the warm liquid up into refrigerant coils, and the heat is then is circulated throughout a home by either a forced air or a hydronic system. During cooling season the exact opposite happens: the pump draws heat from your home and transfers it underground via those same buried loops. Oh, and somewhere along the way, various geothermal systems also provide domestic hot water.

The crucial difference between a geothermal heat pump and a typical furnace is that a heat pump doesn’t ignite fuel to generate heat. Rather, it takes heat that already exists and simply moves it around. That naturally makes it a much more efficient heating and cooling system. Understand this, too: underground temperatures most often stay at around 50º F year round. And that means? A geothermal heating and cooling system uses substantially less energy to cool your home than typical air conditioners.
