The Simple Features and Functions of a Geothermal Heat Pump

What pretty much all homeowners say they love most 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 needing maintenance. And that alone goes far in lowering the overall energy costs of Ord homeowners who’ve gone geothermal.

 

That said, there are some moving parts in the system. the majority 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. Thus, it’s a furnace and an air conditioner rolled into one unobtrusive package.

How the heat pump transfers heat is with water or an antifreeze solution. This liquid circulates 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 from that point the heat is dispensed throughout a home by means 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 perk, various geothermal systems also supply domestic hot water.

The fundamental differentiator between a geothermal heat pump and a conventional furnace is that a heat pump doesn’t set fuel afire to generate heat. Instead it takes heat that’s already present 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 year round. And that means? A geothermal heating and cooling system uses significantly less energy to cool your home than typical air conditioners.
