The Fundamental Features and Functions of a Geothermal Heat Pump

What the great majority of homeowners say they appreciate best about a geothermal heating and cooling system is that it has so few moving parts. There’s just that much less that can fall apart– that much less requiring maintenance. And that alone plays a significant role in decreasing the overall energy costs of Manhattan homeowners who’ve gone geothermal.

 

Still, there are some moving parts in the system. the majority of them are found in its most conspicuous component, too: the geothermal heat pump.

This is the system’s powerplant. Its job 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 rolled into one compact package.

How the heat pump transfers heat is with water or an antifreeze solution. This liquid circulates through pipe loops buried underground and connected to the heat pump, which is positioned above ground. During heating season the liquid draws heat from the ground, the heat pump draws the warm liquid up into refrigerant coils, and from that point the heat is dispensed throughout a home by 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 through those same buried loops. Oh, and somewhere in all this, lots of geothermal systems also supply domestic hot water.

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