The 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 go bad– that much less requiring maintenance. And that in itself makes a big difference in reducing the overall energy costs of Reading homeowners who’ve gone geothermal.

 

Of course, the system isn’t totally devoid of 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 role 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. Consequently, it’s a furnace and an air conditioner combined in one unobtrusive package.

Water – or an antifreeze solution – is the medium the heat pump uses to transfer heat. 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 dispensed throughout a home by means of either a forced air or a hydronic system. During cooling season the exact opposite happens: the pump draws heat from your home and transfers it to the ground via those same buried loops. Oh, and somewhere in all this, many geothermal systems also supply domestic hot water.

The essential difference between a geothermal heat pump and a ordinary furnace is that a heat pump doesn’t burn fuel to generate heat. No, indeed, it takes heat that’s already there and simply moves it around. That naturally makes it a much more efficient heating and cooling system. Bear this in mind, too: underground temperatures almost always hold at around 50º F all year long. And that means? A geothermal heating and cooling system requires substantially less energy to cool your home than typical air conditioners.
