The Simple Properties and Purposes of a Geothermal Heat Pump

What the great majority of people say they love most of all about a geothermal heating and cooling system is that it has almost no moving parts. There’s just that much less that can break down– that much less needing maintenance. And that alone goes far in decreasing the overall energy costs of Lansing homeowners who’ve gone geothermal.

 

That said, the system does have some moving parts. Most of them are found in its most essential 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 ambient temperatures. In Consequence, it’s a furnace and an air conditioner rolled into one discreet package.

Water – or an antifreeze solution – is the medium the heat pump uses to transfer heat. This liquid flows 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 the heat is then is conveyed throughout a home by way of either a forced air or a hydronic system. During cooling season it runs in reverse: the pump draws heat from your home and transfers it to the ground through those same buried loops. Oh, and as an added bonus, many geothermal systems also produce domestic hot water.

The crucial difference between a geothermal heat pump and a typical furnace is that a heat pump doesn’t set fuel burning to generate heat. Instead it takes heat that’s already there and just moves it around. That naturally makes it a much more efficient heating and cooling system. Bear this in mind, too: underground temperatures generally remain at around 50º F all year long. The payoff? A geothermal heating and cooling system uses considerably less energy to cool your home than regular air conditioners.
