Water-to-Water Heat Pump Systems
Water-to-water heat pump systems from Bosch.
Water-to-water heat pump systems are highly efficient heating and cooling solutions that utilize water as the heat transfer medium. These systems extract heat from a water source, such as a well, lake, or river, and transfer it to a hydronic heating system for indoor space heating or to a water-based cooling system for cooling purposes. The heat pump unit circulates a refrigerant through an evaporator coil, absorbing heat from the water source. The refrigerant is then compressed, increasing its temperature, and the heat is transferred to the desired heating or cooling system.
Bosch water-to-water heat pump systems offer efficient and reliable temperature control for the home. Explore rebates and tax credits on Bosch water-to-water geothermal heat pump systems in your area.
