High pressure solar hot water system - thermo siphon (for use with solar or existing geyser). This method does not use the pump or controller but rather relies on heat convection to circulate the heated water through the geyser. This is the most economic operation. For this installation the collector must be mounted horizontal and the top of the collector must be at a lower level than the geyser. No controller pump is used as the water is circulated through thermo siphon.
