solare Wasser-Geysire / Wohn-Solar-Warmwasser-h

solar water geysers with assist tank All stainless steel solar hot water(SBT-NP),thermosyphon(passive system) The principle The series solar water heaters employ the natural convection phenomenon called "thermosyphon", which results in hot water being lighter than coldwater. The water heated in the tubes rises through the solar collector to enter the storage tank, while the cold water at the bottom of the tank flows into the tubes, creating continuous circulation. The convection flow will continue as long as the sun is heating the collector.
