What Is geothermal

Outside, temperatures fluctuate with the changing seasons, but underground temperatures don’t change nearly as dramatically, thanks to the mass of the earth. Four to eight feet below the ground, the temperature remains relatively constant year round. A Bosch geothermal system, which typically consists of an indoor heat pump and a buried system of pipes called a ground loop, and/or a well system, capitalizes on these constant temperatures to provide “free” energy.


In summer time, the process reverses, and the cooler earth absorbs the heat from the home, returning cooler fluid to the Bosch geothermal heat pump. This fluid is typically cooler than the outside temperatures, providing a more efficient operation and energy savings.benefits of geothermal

Winter heating mode

In winter time, fluid circulating through the earth loop (or well) absorbs stored heat from the ground and carries it indoors. The Bosch geothermal heat pump compresses the heat to a higher temperature and distributes it throughout the home.

tax credit information

In February 2018, the 30% geothermal federal tax credit was reinstated through 2019 and can be retroactively applied to installations “placed in service” on January 1, 2017 or later. Property is usually considered to be placed in service when installation is complete and equipment is ready for use. However, if the system is part of the construction or renovation of a house, it’s considered placed in service when the taxpayer takes residence in the house.
