Bosch System

Bosch’s geothermal heat pump is a highly energy efficient and cost-effective system. The technology uses the relatively constant temperature of the earth (thermal energy) to provide heating, air conditioning and hot water.

The Bosch geothermal systems use the earth as a heat source and sink. In order to transfer heat to or from the building, heat exchangers (ground loops) are installed in the ground. These consist of high-density polyethylene plastic pipes. The loops are then connected to the heat pump and fluid (water) is circulated between them transferring the heat between the heat pump and earth.

This water-based system is also effective in dams, lakes, wells, or in any body of water that has a constant depth of minimum 2m and a relevant constant temperature. Open loops are where the fluid used is the body of water with the energy recovered through the heat pump and the water returned to the source. Closed loops are coils of polyethylene pipes submerged in the body of water with water circulated to an from the heat pump.
