The How and Why of a Geothermal Heat Pump

One of the great 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 by itself makes a significant difference in reducing the overall energy costs of Omaha homeowners who’ve gone geothermal.

 

Still, the system is not without any moving parts. 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 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 weather30. In Consequence, it’s a furnace and an air conditioner united in one unobtrusive package.

The medium a heat pump uses to transfer heat is either water or an antifreeze solution. This liquid flows through pipe loops buried underground and linked 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 underground via those same buried loops. Oh, and somewhere in all this, many geothermal systems also supply domestic hot water.

The basic distinction between a geothermal heat pump and a common furnace is that a heat pump doesn’t set fuel afire to generate heat. No, indeed, 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 most often stay at around 50º F year round. And that means? A geothermal heating and cooling system requires significantly less energy to cool your home than traditional air conditioners.
