Residential Water-to-Air Heat Pump Systems

Water-to-air heat pump systems from Bosch.

Bosch geothermal heat pump systems are built to be ultra-efficient with low operating costs. Water-to-air geothermal heat pump systems utilize the stable temperature of the earth's ground or water sources to provide efficient heating and cooling. These systems consist of a ground or water loop connected to an indoor unit. In heating mode, the water or antifreeze solution in the loop absorbs heat from the ground or water source and carries it to the heat pump. The heat pump then extracts the heat and releases it indoors to warm the house. During cooling, the process is reversed, with the heat pump extracting heat from indoor air and transferring it back to the ground or water source.

Bosch water-to-air geothermal heat pump systems offer exceptional energy efficiency, as well as rebates and tax credits. Explore rebates and tax credits on Bosch water-to-air geothermal heat pump systems in your area.
