Non-pressure Stainless Steel Solar Water Heaters  

Non-pressure Stainless Steel Solar Water Heater is an economic system with higher efficiency. The water heated in the tubes rises through the solar collector to enter the 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 heats the collector. The simple controller can be used to show water temperature, level and control cold water supply or electric element work at set time.
