The Features and Functions of a Geothermal Heat Pump

What most people say they love most of all about a geothermal heating and cooling system is that it has almost no moving parts. There’s just that much less that can get screwed up– that much less to need maintenance. And that alone makes a significant difference in cutting the overall energy costs of Southern Ohio homeowners who’ve gone geothermal.

 

Still, 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 system’s powerplant. 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. In Consequence, it’s a furnace and an air conditioner integrated into one unobtrusive package.

What, then, does a heat pump use to transfer heat? Water! Well, that or a solution incorporating antifreeze. This liquid courses through loops of underground pipes to which the heat pump is secured above ground. 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 way of either a forced air or a hydronic system. During cooling season it runs in reverse: the pump draws heat from your home and transfers it underground via those same buried loops. Oh, and as an extra perk, lots of geothermal systems also supply domestic hot water.

The fundamental differentiator between a geothermal heat pump and a typical furnace is that a heat pump doesn’t set fuel afire to generate heat. Instead it takes heat that already exists 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 through the year. The upshot? A geothermal heating and cooling system uses considerably less energy to cool your home than regular air conditioners.
