Passive Solar Water Heater

The passive solar water heater absorbs solar energy and transmits it to the water tank through circulation,When the temperature of the collector reaches the set value,the controller starts the circulation pump automatically.The circulation pump makes heat-conductiong liquid circulate automatically.Then the heat-conducting liquid transfers heat to water by heat exchanger in the tank to heat the water.The highest temperature of water tank can be 95 degree Celsius, During this process, this system doesn't need any power, just under the sunshine.
Passive solar water heater are mainly export to Hungary, Germany, Austria and so on. Not only selling well in Malta, Spain, Portugal,,but also popular in  Rwanda, Burundi, Seychelles etc.
