Pond and Lake Applications Burying pipe underground isn’t the only route if you’re looking into geothermal energy in Nashville. While it could seem a tad odd that your pond could be helping to heat and cool your home, ponds and lakes are great options when it comes to capturing geothermal energy. These geothermal loops are closed loop systems like the others we put in, and are merely sitting near the bottom of the pond or lake. Much like the evenness of ground temperatures, pond and lake temperatures are very even at the bottom. The materials used for pond and lake applications are also nearly identical, and there are only a couple differences when it comes to length and configuration. Requirements A 1/2 to 3/4 acre, 8-foot-deep body of water is usually the regular size needed for an average home. Pond and lake geothermal systems can be less pricey than the conventional two earth loop options as well. As with most heating and cooling systems, geothermal pond loops will depend on your individual situation, proper geothermal loop design, as well as the size of your pond or lake and its depth. The team at Donelson Air Service Experts Heating & Air Conditioning is skilled and has the experience to give you an estimate once we have taken a look to decide if your pond is fit to house a geothermal system. Once it’s decided that your pond is able to harness geothermal energy, we will create a custom design and install a pond system that not only provides you with geothermal heating and cooling, but might actually provide increased performance and possibly save on installation costs.
