The Simple How and Why of a Geothermal Heat Pump

One of the best things about a geothermal heating and cooling system is that it has so few moving parts. There’s just that much less that can go wrong– that much less to need maintenance. And that alone makes a significant difference in slashing the overall energy costs of Huntington 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 system’s powerplant. 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 the weather30. As such, it’s a furnace and an air conditioner united in one discreet 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 conveyed throughout a home by 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 earth by way of those same buried loops. Oh, and as an extra bonus, more than a few geothermal systems also supply domestic hot water.

The critical differentiator between a geothermal heat pump and a conventional furnace is that a heat pump doesn’t set fuel burning to generate heat. Instead it takes heat that already exists and just moves it around. That naturally makes it a much more efficient heating and cooling system. Recognize this, too: underground temperatures almost always hold at around 50º F year round. Result? A geothermal heating and cooling system uses substantially less energy to cool your home than standard air conditioners.
