Green Tech’s non-Pressure thermosiphon systems offer excellent quality with minimal installation effort. The systems are independent of the existing hot water system and do not have to be integrated into existing systems. The self-sufficient system uses the principle of gravity and therefore requires no circulation pump, no electronic control and therefore no connection to the power supply.

This non-pressurized solar thermal system is ideal for heating hot water for a garden shower, a summer house shower and for swimming pools.
