The Simple Properties and Purposes of a Geothermal Heat Pump

One of the best things 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 keep up. And that alone goes far in lowering the overall energy costs of Des Moines homeowners who’ve gone geothermal.

 

That said, there are some moving parts in the system. the bulk of them are found in its most vital 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 the weather30. That being the case, 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 courses through pipe loops installed underground and attached to the heat pump, which is kept 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 circulated throughout a home by way of either a forced air or a hydronic system. During cooling season the process runs in reverse: the pump draws heat from your home and transfers it underground through those same buried loops. Oh, and as an added perk, many geothermal systems also supply domestic hot water.

The essential difference between a geothermal heat pump and a more familiar furnace is that a heat pump doesn’t ignite fuel to generate heat. No, indeed, 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 typically remain at around 50º F all year long. The payoff? A geothermal heating and cooling system requires substantially less energy to cool your home than typical air conditioners.
