all stainless steel Integrative Pressurized heat pipe Solar Water Heaters

Integrative Pressurized Solar Water Heater compose of pressure solar tank, high performance vacuum tube with heat pipe and strong galvanized steel frame. The Vacuum tube absorbs solar energy, and conductive copper pipe(heat pipe) transfers the heat into the pressurized water tank. In this case, the water inside the tank becomes hot. With the design of no water inside vacuum tube, the system will keep work even one or more tube was broken by accident or in a freezing area.
