The Simple Properties and Purposes of a Geothermal Heat Pump

What almost everybody says they like most of all about a geothermal heating and cooling system is that it has so little in the way of moving parts. There’s just that much less that can go bad– that much less needing maintenance. And that alone makes a significant difference in cutting the overall energy costs of Dallas homeowners who’ve gone geothermal.


Of course, the system does have some moving parts. 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 job is to transfer heat. And it transfers heat either from the ground into your house or from your house into the ground, depending on ambient temperatures. Consequently, it’s a furnace and an air conditioner united in one compact package.

Water – or an antifreeze solution – is the medium the heat pump uses to transfer heat. This liquid courses through underground loops of pipe that are linked 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 the heat is then is distributed throughout a home by means 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 earth via those same buried loops. Oh, and somewhere in the process, more than a few geothermal systems also provide domestic hot water.

The crucial distinction between a geothermal heat pump and a typical furnace is that a heat pump doesn’t burn fuel 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. Remember this, too: underground temperatures usually remain at around 50º F through the year. The upshot? A geothermal heating and cooling system uses considerably less energy to cool your home than typical air conditioners.
