The Basic 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 almost no moving parts. There’s just that much less that can go haywire– that much less to need maintenance. And that alone plays a huge role in cutting the overall energy costs of Fort Wayne homeowners who’ve gone geothermal.

 

Still, 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 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 ambient temperatures. Consequently, it’s a furnace and an air conditioner integrated into one unobtrusive package.

How the heat pump transfers heat is with water or an antifreeze solution. This liquid courses 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 there 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 to the earth via those same buried loops. Oh, and somewhere along the way, many geothermal systems also supply domestic hot water.

The basic distinction between a geothermal heat pump and a ordinary furnace is that a heat pump doesn’t set fuel burning 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. Recognize this, too: underground temperatures typically remain at around 50º F year round. The upshot? A geothermal heating and cooling system uses significantly less energy to cool your home than standard air conditioners.
