The Fundamental How and Why of a Geothermal Heat Pump

What most people say they love most 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 wrong– that much less needing maintenance. And that by itself plays a major role in reducing the overall energy costs of Rochester homeowners who’ve gone geothermal.

 

Of course, the system is not without any moving parts. Most of them are found in its most vital 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 seasonal temperatures. In Consequence, it’s a furnace and an air conditioner united in 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 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 from that point the heat is distributed throughout a home by way of either a forced air or a hydronic system. During cooling season it runs the other way ’round: the pump draws heat from your home and transfers it underground by way of those same buried loops. Oh, and somewhere along the way, various geothermal systems also supply domestic hot water.

The essential difference between a geothermal heat pump and a standard furnace is that a heat pump doesn’t burn fuel to generate heat. Instead it takes heat that’s already there and merely moves it around. That naturally makes it a much more efficient heating and cooling system. Keep this in mind, too: underground temperatures generally remain at around 50º F year round. And that means? A geothermal heating and cooling system uses substantially less energy to cool your home than standard air conditioners.
