The Fundamental Properties and Purposes of a Geothermal Heat Pump

One of the best things 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 makes a significant difference in lowering the overall energy costs of The Hudson Valley homeowners who’ve gone geothermal.


Of course, the system does have some moving parts. the better part of them are found in its most vital 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 seasonal temperatures. In Consequence, it’s a furnace and an air conditioner integrated into one discreet package.

The medium by which a heat pump transfers heat is either water or an antifreeze solution. This liquid circulates through loops of underground pipes to which the heat pump is connected 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 conveyed throughout a home by way of either a forced air or a hydronic system. During cooling season the process is reversed: the pump draws heat from your home and transfers it to the earth via those same buried loops. Oh, and somewhere in all this, more than a few geothermal systems also produce domestic hot water.

The fundamental differentiator between a geothermal heat pump and a ordinary furnace is that a heat pump doesn’t ignite fuel to generate heat. No, indeed, it takes heat that already exists and just 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 through the year. The upshot? A geothermal heating and cooling system requires considerably less energy to cool your home than conventional air conditioners.
