How Geothermal Systems Work

The Natural Way

Ground source heat pumps (GSHPs) are electrically powered systems that tap the stored energy of the greatest solar collector in existence—the earth. These systems use the earth's relatively constant temperature to provide heating, cooling, and hot water for homes and commercial buildings.

The earth absorbs almost 50% of all solar energy and remains a nearly constant temperature of 50 degrees to 70 degrees F depending on geographic location. In winter, a food-grade antifreeze solution circulating inside a sealed loop absorbs heat from the earth and carries it to the geothermal unit. Here it is compressed to a higher temperature and sent out as warm air or warm water to your indoor system for circulation throughout your home.

In the summer, the system reverses and expels heat from your home to the cooler earth via the loop system, creating an air conditioned environment. This heat exchange process is not only natural but is a truly ingenious and highly effective way to create a comfortable climate in your home or business.

Customer Testimonial

My wife and I wanted to convert our home heating source to geothermal, or ground source heating, and stop using oil. We had an excellent experience with Earthheat and a very successful project. Please let me explain.

The planning, engineering, installation, and cutover went without a hitch. Also, we now enjoy free hot water as a byproduct of our geothermal heat pump. Earthheat understood our requirements and worked with us every inch of the way.

Anytime we had a question about anything, they were right there ready to help, very professional and customer oriented.

As a general contractor myself, I've had years of experience to know and understand quality, and I'm very pleased and proud to show the craftsmanship of Earthheat to anyone seriously considering ground source heating.

If there were opportunities to save money without compromising the quality, they did not hesitate to help us. They use only the highest quality components. Invoices were very detailed and easy to understand.

Anyone seriously considering ground source (geothermal) heating, I would not hesitate to recommend Earthheat as a contractor.
