The intergrated vacuum tube water solar heater system consists of water tank, frame and vacuum tubes.
The hot water tank is insulated with 50 mm polyurethane, so the hot water in the tank can be stored for a long time.
Vacuum tubes are made of inner and ourter glass pipe. The space between them is a vacuum and this helps to minimize heat loss.
The system can produce hot water even in cloudy days.
