Quick Facts on Geothermal Heating & Cooling

More than ever, it’s important to have your home be energy efficient. Cutting down on your energy usage means you’ll be helping to save the planet and yourself some money. One of the best ways to go about that is by using energy that already exists and can be found right under your home. Geothermal heating and cooling has gained popularity in recent years as homeowners look for ways to cut down on how much they spend on their energy bills. Here are some quick facts on geothermal heating and cooling:


Solar energy is being transmitted constantly by the sun. The atmosphere absorbs approximately 20%, and another 30% is reflected away. Half of it is absorbed by the surface and stored underground, and you can find a consistent temperature year-round from this stored energy. Geothermal heating and cooling systems take advantage of this stored energy to heat and cool your home.


Unlike traditional HVAC systems, fossil fuels do not to be burned nor do you need a great amount of electricity for a geothermal system to operate. These systems simple move heat, and the electricity necessary to run the system’s mechanics equate to an approximately 1/5 of the energy transferred by the system.


The best thing about geothermal systems is that they provide you with a heating and cooling solution that saves you money and doesn’t require the burning of fossil fuels. Another great thing about having a geothermal system is that it’s a durable investment. After having your system installed, you’ll more than likely see an ROI in five to 10 years. The system itself will last for an approximate 25 years, and the underground ground loop can last for half a century.

Minnesota’s untapped potential 

A study from the Natural Resources Research Institute of the University of Minnesota Duluth said that our state has great potential for low-cost geothermal power, according to MinnPost. The study’s lead researcher, Don Fosnacht, told MinnPost, “The potential is three or four times greater than we assumed, and it’s a lot easier to get at than the earlier reports indicated.”
