The Basic Properties and Purposes of a Geothermal Heat Pump

One of the most appreciated 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 wrong– that much less to need maintenance. And that alone goes far in cutting the overall energy costs of Mountain Home homeowners who’ve gone geothermal.

 

Of course, there are some moving parts in the system. the majority of them are found in its most critical 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 the season30. Thus, it’s a furnace and an air conditioner united in one unobtrusive package.

Water – or an antifreeze solution – is the medium by which the heat pump transfers heat. This liquid courses through pipe loops installed underground and secured to the heat pump, which is positioned 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 way of either a forced air or a hydronic system. During cooling season the process is reversed: the pump draws heat from your home and transfers it to the ground by way of those same buried loops. Oh, and as an extra perk, various geothermal systems also supply domestic hot water.

The basic distinction between a geothermal heat pump and a more familiar furnace is that a heat pump doesn’t ignite fuel to generate heat. Instead it takes heat that already exists and simply moves it around. That naturally makes it a much more efficient heating and cooling system. Keep this in mind, too: underground temperatures usually remain at around 50º F year round. Result? A geothermal heating and cooling system requires significantly less energy to cool your home than typical air conditioners.
