It’s underground, right below your feet! For example, in Pennsylvania and the surrounding states, the underground temperature is an energy efficient 58ºF. GroundSource Energy (GSE) is a system that heats and cools homes, offices, schools, restaurants or any other structure, using the heat from the sun stored in the ground beneath us.
So, how do we use 58°F temperatures to heat and cool our homes?
Natural Energy Solutions uses a simple but highly efficient device called a Ground Source Heat Pump (GSHP). Unlike the energy-robbing air source heat pumps that try to use outside air to heat and cool our homes, GSHP’s use the heat created by the sun and stored in the earth. This eco-friendly, totally
sustainable technology frees you and the environment from all types of combustible fuels and finally allows you to eliminate your dependence on oil, gas and other fossil fuels, shielding you from their ever-escalating prices.
How do Ground Source Heat Pumps work?
The simplest explanation is just like your refrigerator, a similar closed system that exchanges hot
and cold. Heat IN for the winter; heat OUT for the summer. Heat can be “pumped” from one location
to another and “exchanged” with cooler temperatures, hence the term Ground Source Heat Pump. Simple, quiet, ecologically friendly and inexpensive. The system is a series of “closed” loops that take nothing from the earth and discharge nothing back, except in certain rare but efficient open loop designs. A ground loop made with HDPE pipe will be designed and installed to use as the energy exchange between the structure and the earth. The ground loop can be installed in a variety of ways but generally will be either vertical boreholes, horizontal trenches or even placed in a pond or lake.
The type of loop will be selected based on many factors, such as available land, soil and rock structures, size of the structure and other land use issues. In most cases, the loop will be a “closed” loop which is filled with water and conditioner and will continue to circulate through the loop for the life of the system. Open loops can be considered in certain applications. The ground loops are then connected to the Ground Source Heat Pump (GSHP) which contains a closed refrigeration loop and an optional domestic hot water loop. The GSHP is then connected to the air or hydronic circulation loop to heat and cool the structure. |
