The HPB water heater incorporates an air-water heat pump.
The peculiarity of this solution is that it draws energy from the ambient air: either from the room where it is installed or externally, depending on the type of installation.
By using ambient air, the water heater harnesses the heat from the air to heat domestic water, ensuring significant energy savings.
The system can also be considered as a true energy storage, as it allows for the accumulation of a large quantity of hot water produced ideally through clean energy sources (photovoltaic, solar, thermal), thus reducing CO2 emissions into the air.
