The Simple Properties and Purposes of a Geothermal Heat Pump

What pretty much all people say they appreciate most about a geothermal heating and cooling system is that it has almost no moving parts. There’s just that much less that can get screwed up– that much less needing maintenance. And that by itself plays a huge role in cutting the overall energy costs of Omaha homeowners who’ve gone geothermal.

 

That said, the system does have some moving parts. Most of them are found in its most important component, too: the geothermal heat pump.

This is the system’s engine. Its purpose 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 climate30. Consequently, it’s a furnace and an air conditioner combined in one compact package.

The medium a heat pump uses to transfer heat is either water or an antifreeze solution. This liquid flows through loops of underground pipes to which the heat pump is secured above ground. During heating season the liquid draws heat from the ground, the heat pump draws the warm liquid up into refrigerant coils, and from there the heat is distributed throughout a home by either a forced air or a hydronic system. During cooling season the process runs in reverse: 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 produce domestic hot water.

The crucial difference between a geothermal heat pump and a standard furnace is that a heat pump doesn’t burn fuel to generate heat. Rather, it takes heat that’s already there and merely moves it around. That naturally makes it a much more efficient heating and cooling system. Keep this in mind, too: underground temperatures almost always hold at around 50º F all year long. And that means? A geothermal heating and cooling system uses significantly less energy to cool your home than traditional air conditioners.
