BEFA pressureless thermosiphon systems (solar collector)

BEFA pressureless thermosiphon systems (BDS) are characterized by their outstanding quality and minimal installation effort. These systems operate independently of existing hot water preparation and do not need to be integrated into existing systems. The autonomous system operates according to the gravity principle and therefore requires neither a circulation pump nor an electronic control system or a power connection. Our pressureless solar thermal system is ideal for heating hot water for a garden shower, a shower in a summer house, or for swimming pools. Note: The tank is not designed for high water pressure. In this case, we recommend installing a pressure reducer upstream of the solar tank.
