The Simple Features and Functions 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 go bad– that much less to maintain. And that alone makes a significant difference in reducing the overall energy costs of Michigan homeowners who’ve gone geothermal.

 

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

This is the system’s engine. 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 the weather30. As such, it’s a furnace and an air conditioner integrated into one compact package.

The medium a heat pump uses to transfer heat is either water or an antifreeze solution. This liquid courses through underground loops of pipe that are secured 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 from there the heat is dispensed throughout a home by way of 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 to the earth through those same buried loops. Oh, and as an added bonus, lots of 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. Bear this in mind, too: underground temperatures usually remain at around 50º F through the year. Result? A geothermal heating and cooling system uses substantially less energy to cool your home than conventional air conditioners.
