The Simple Properties and Purposes of a Geothermal Heat Pump

What almost everybody says they appreciate best about a geothermal heating and cooling system is that it has so little in the way of moving parts. There’s just that much less that can go bad– that much less to maintain. And that alone plays a huge role in lowering the overall energy costs of Lime Springs homeowners who’ve gone geothermal.

 

That said, the system does have some moving parts. the bulk 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 weather30. As such, it’s a furnace and an air conditioner rolled into one discreet package.

How the heat pump transfers heat is with water or an antifreeze solution. This liquid circulates through loops of underground pipes to which the heat pump is linked 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 way of either a forced air or a hydronic system. During cooling season the process is reversed: the pump draws heat from your home and transfers it to the ground via those same buried loops. Oh, and as an extra perk, various geothermal systems also provide domestic hot water.

The basic distinction 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’s already present and just moves it around. That naturally makes it a much more efficient heating and cooling system. Recognize this, too: underground temperatures almost always remain at around 50º F year round. Result? A geothermal heating and cooling system requires significantly less energy to cool your home than regular air conditioners.
