The Fundamental Properties and Purposes of a Geothermal Heat Pump

One of the great 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 requiring maintenance. And that alone plays a significant role in cutting the overall energy costs of Port Washington homeowners who’ve gone geothermal.

 

Of course, 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 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 united in one compact package.

The medium by which a heat pump transfers heat is either 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 circulated throughout a home by means of either a forced air or a hydronic system. During cooling season it runs the other way ’round: the pump draws heat from your home and transfers it underground by way of those same buried loops. Oh, and somewhere along the way, many geothermal systems also supply domestic hot water.

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