The Basic Features and Functions of a Geothermal Heat Pump

What the great majority of homeowners 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 go haywire– that much less to maintain. And that by itself plays a significant role in slashing the overall energy costs of Indianapolis homeowners who’ve gone geothermal.

 

That said, 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 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 ambient temperatures. In Consequence, it’s a furnace and an air conditioner combined in one compact package.

The medium by which a heat pump transfers heat is either water or an antifreeze solution. This liquid courses 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 the heat is then is circulated throughout a home by means of 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 via those same buried loops. Oh, and somewhere in all this, many geothermal systems also produce domestic hot water.

The fundamental differentiator between a geothermal heat pump and a standard furnace is that a heat pump doesn’t burn fuel to generate heat. Instead 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 almost always hold at around 50º F all year long. Result? A geothermal heating and cooling system uses significantly less energy to cool your home than typical air conditioners.
