The Simple Properties and Purposes of a Geothermal Heat Pump

One of the most appreciated things about a geothermal heating and cooling system is that it has almost no moving parts. There’s just that much less that can break down– that much less to keep up. And that in itself makes a significant difference in slashing the overall energy costs of Annapolis homeowners who’ve gone geothermal.

 

That said, the system is not without any moving parts. Most 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. As such, it’s a furnace and an air conditioner combined in one discreet package.

How the heat pump transfers heat is with water or an antifreeze solution. This liquid flows through loops of underground pipes to which the heat pump is attached 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 means 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 ground via those same buried loops. Oh, and somewhere in the process, more than a few geothermal systems also supply domestic hot water.

The basic distinction between a geothermal heat pump and a traditional furnace is that a heat pump doesn’t set fuel burning 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. Keep this in mind, too: underground temperatures most often stay at around 50º F through the year. Result? A geothermal heating and cooling system requires considerably less energy to cool your home than regular air conditioners.
