The Basic Properties and Purposes of a Geothermal Heat Pump

One of the best things 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 in itself plays a major role in reducing the overall energy costs of Green Bay homeowners who’ve gone geothermal.

 

That said, the system is not without any moving parts. the bulk of them are found in its most conspicuous component, too: the geothermal heat pump.

This is the engine that drives the system. Its role 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. That being the case, it’s a furnace and an air conditioner rolled into 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 loops of underground pipes to which the heat pump is connected 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 either a forced air or a hydronic system. During cooling season the exact opposite happens: the pump draws heat from your home and transfers it underground via those same buried loops. Oh, and somewhere in all this, many 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. No, indeed, it takes heat that’s already present and just moves it around. That naturally makes it a much more efficient heating and cooling system. Understand this, too: underground temperatures most often stay at around 50º F through the year. Result? A geothermal heating and cooling system requires considerably less energy to cool your home than standard air conditioners.
