The Simple Properties and Purposes of a Geothermal Heat Pump

What almost everybody says they appreciate most about a geothermal heating and cooling system is that it has almost no moving parts. There’s just that much less that can break down– that much less to maintain. And that alone plays a major role in lowering the overall energy costs of Rochester homeowners who’ve gone geothermal.

 

That said, the system is not without any 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 task 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. In Consequence, it’s a furnace and an air conditioner united in one discreet package.

What, then, does a heat pump use to transfer heat? Water! Well, that or a solution incorporating antifreeze. 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 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 by way of those same buried loops. Oh, and somewhere along the way, more than a few geothermal systems also supply domestic hot water.

The essential difference between a geothermal heat pump and a typical furnace is that a heat pump doesn’t set fuel afire to generate heat. Rather, it takes heat that already exists and just moves it around. That naturally makes it a much more efficient heating and cooling system. Understand this, too: underground temperatures almost always hold at around 50º F all year long. The payoff? A geothermal heating and cooling system requires substantially less energy to cool your home than traditional air conditioners.
