6)Thermopump 'Water-Water' for heating, cooling and domestic hot water
Thermopump Water_Water
Thermopumps use the energy of underground water (drilling, well, etc). Due to their high level of efficiency (thanks to the constant temperature of underground water all year long), they find a wide application in small one-family houses, as well as in apartments and hotels. The electricity is used for cooling the colder body (the water) and heating the warmer body (the rooms). Thermopumps can work also in a cooling regime, and regardless of the working regime supply domestic hot water for a boiler with intergrated serpentine. It is possible the system to work only for boiler heating, when neither heating, nor cooling is necessary. Standard efficiency: Energy Conversion Efficiency: 400% - 500%
