The Basic Properties and Purposes of a Geothermal Heat Pump

What pretty much all homeowners say they appreciate most of all 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 alone goes a long way toward decreasing the overall energy costs of Columbus, Ohio homeowners who’ve gone geothermal.

 

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

This is the engine that drives the system. 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. As such, it’s a furnace and an air conditioner combined in one unobtrusive package.

How the heat pump transfers heat is with water or an antifreeze solution. This liquid circulates through underground loops of pipe that are attached 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 from that point the heat is dispensed throughout a home by either a forced air or a hydronic system. During cooling season the process runs in reverse: the pump draws heat from your home and transfers it to the earth by way of those same buried loops. Oh, and somewhere in all this, lots of geothermal systems also provide domestic hot water.

The critical differentiator between a geothermal heat pump and a traditional furnace is that a heat pump doesn’t set fuel burning to generate heat. No, indeed, it takes heat that already exists and simply moves it around. That naturally makes it a much more efficient heating and cooling system. Keep this in mind, too: underground temperatures typically remain at around 50º F through the year. Result? A geothermal heating and cooling system requires significantly less energy to cool your home than standard air conditioners.
