The Fundamental Properties and Purposes of a Geothermal Heat Pump

One of the most remarkable things about a geothermal heating and cooling system is that it has so few moving parts. There’s just that much less that can break down– that much less requiring maintenance. And that by itself makes a significant difference in lowering the overall energy costs of Central New Jersey homeowners who’ve gone geothermal.

 

Of course, the system isn’t totally devoid of moving parts. Most 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 seasonal temperatures. As such, 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 circulates through underground loops of pipe that are linked 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 circulated throughout a home by way of 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 underground via those same buried loops. Oh, and as an extra bonus, more than a few geothermal systems also provide domestic hot water.

The crucial difference between a geothermal heat pump and a standard furnace is that a heat pump doesn’t ignite fuel to generate heat. No, indeed, it takes heat that’s already there and simply moves it around. That naturally makes it a much more efficient heating and cooling system. Remember this, too: underground temperatures typically remain at around 50º F all year long. And that means? A geothermal heating and cooling system uses considerably less energy to cool your home than standard air conditioners.
