The Fundamental Properties and Purposes of a Geothermal Heat Pump

What the great majority of people say they like 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 wrong– that much less to maintain. And that in and of itself goes a long way toward reducing the overall energy costs of Jasper homeowners who’ve gone geothermal.


That said, the system does have some moving parts. the better part of them are found in its most essential 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 the weather30. Consequently, it’s a furnace and an air conditioner integrated into one unobtrusive package.

The medium by which a heat pump transfers heat is either water or an antifreeze solution. This liquid flows through underground loops of pipe that are connected to the above-ground heat pump. 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 means 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 earth through those same buried loops. Oh, and somewhere along the way, more than a few geothermal systems also supply domestic hot water.

The basic distinction between a geothermal heat pump and a traditional furnace is that a heat pump doesn’t set fuel burning to generate heat. Rather, it takes heat that’s already present 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 substantially less energy to cool your home than regular air conditioners.
