TERRASource Geothermal DIY is an organization that is primarily focused on the distribution of pre-engineered “do it yourself” home geothermal heat pump systems. It’s a mouthful, but the short of it is that they sell heat pumps that tap into underground (“geothermal”) temperatures to regulate home heating and cooling.

How it Works:The upper 10 feet of Earth’s surface maintains a constant temperature between 50 and 60 degrees Fahrenheit, depending on latitude.TERRASource geothermal systems use a closed-loop system to circulate carrier fluids through tubing buried in the ground.read more: terrasource
As the fluid circulates, it absorbs heat from its surroundings, and on its return, the now warmer fluid passes through a heat pump which uses electricity to extract the heat from the fluid.The re-chilled fluid is sent back through the underground tubing to continue the cycle. The heat extracted from underground is a byproduct used to heat/cool the home.

More heating/cooling is generated through a TERRASource geothermal system than if electricity alone had been used to control indoor temperatures. HVAC systems have to work in very hot outdoor temperatures in the summer, and very cold outdoor temperatures in the winter. Conventional HVAC systems have to work twice as hard to achieve and then maintain a constant temperature indoors. The inefficiency of an HVAC is evident at the end of the month when you receive your energy bill.
