Inside a Geothermal Heat Pump

Recently, many inquisitive Denver residents have asked Denver Geothermal Heating about geothermal. Sure, geothermal heat pumps use the earth to condition your home... but how do they do it?

This amazing system works thanks to one simple principle: Given the opportunity, heat will always move into a cooler area. That's why an ice cube melts and it's what makes a geothermal heat pump possible. Here's how geothermal works :

A geothermal system doesn't create heat through combustion. It simply collects and moves it using the principle stated above. In order to carry heat energy from one major component of the system to another, a special liquid called refrigerant is used. The refrigerant is circulated throughout the system by a powerful centrifugal pump called a compressor.

During the winter, heat from the earth is absorbed into the loop water and carried up to the coaxial coil. Again, the inner tube of the coil contains water from the loop while the outer tube contains cold refrigerant. The loop water passes its warmth through the walls of the coil and heats the refrigerant. The refrigerant carries that heat into the compressor where it’s put under a substantial portion of pressure - making it exceedingly hot.

To cool your home, the system literally reverses the entire process using a reversing valve. Refrigerant flows in the opposite direction and order of components.
