1.Water is rapidly heated by the heat pipe.

2.There is no water in the vacuum tube, so the tube will not break in winter

3.The small size of the collector allows for versatile architectonic integration

4.Collector can be combined with existing pipeline.

5.The collector can operate even in case of a broken tube. A single tube can, ifnecessary, be exchanged without interruption of the heating cycle.

1.Heat pipe(copper)solar collector.

2Insuation:Polyurethane,thickness:50mm

3Vent connection(inch):1/2

4.Temperature of water can be heated to:85 degree,need 3-4hours.

5.In rainy days:It keep temperature for 72 hours(But the temperature will decrease about 5-10 degree)

8.Electric heater:When there's no sun,it can be heated by electric heater.(We will add or not as to your requests)
