The Simple Properties and Purposes of a Geothermal Heat Pump

What practically everyone says they like most 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 makes a great difference in reducing the overall energy costs of Maryville homeowners who’ve gone geothermal.

 

Still, the system does have some moving parts. the better part of them are found in its most important component, too: the geothermal heat pump.

This is the engine that drives the system. Its job is to transfer heat. And it transfers heat either from the ground into your house or from your house into the ground, depending on ambient temperatures. Consequently, it’s a furnace and an air conditioner integrated into one compact package.

The medium by which a heat pump transfers heat is either water or an antifreeze solution. This liquid circulates through underground loops of pipe that are connected to the above-ground heat pump. 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 it runs in reverse: the pump draws heat from your home and transfers it underground by way of those same buried loops. Oh, and somewhere along the way, more than a few geothermal systems also produce domestic hot water.

The fundamental differentiator between a geothermal heat pump and a typical furnace is that a heat pump doesn’t set fuel afire to generate heat. No, indeed, it takes heat that already exists and simply moves it around. That naturally makes it a much more efficient heating and cooling system. Remember this, too: underground temperatures most often stay at around 50º F all year long. The payoff? A geothermal heating and cooling system requires substantially less energy to cool your home than regular air conditioners.
