The Fundamental Features and Functions of a Geothermal Heat Pump

One of the most appreciated things 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 to keep up. And that by itself plays a significant role in lowering the overall energy costs of Central homeowners who’ve gone geothermal.

 

That said, the system is not without any moving parts. Most of them are found in its most vital component, too: the geothermal heat pump.

This is the system’s workhorse. 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 the weather30. That being the case, it’s a furnace and an air conditioner rolled into one compact package.

What, then, does a heat pump use to transfer heat? Water! Well, that or a solution incorporating antifreeze. This liquid flows 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 from there the heat 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 underground via those same buried loops. Oh, and as an extra bonus, lots of geothermal systems also provide domestic hot water.

The fundamental differentiator between a geothermal heat pump and a ordinary furnace is that a heat pump doesn’t set fuel afire to generate heat. Instead it takes heat that’s already there and just 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 uses significantly less energy to cool your home than standard air conditioners.
