Integrated pressurized Solar water heater is working with high pressure, so do the water it produces. It uses the heat pipe to deliver the heat energy, it can work rapidly. Each tube can work alone, so it can still work in the event of occasional tube breakage. It has some advantages of no water in tube, no filthy, no broken tube, anti-freeze, unlimited time of the inputting water and pressure operation. Insulation adopts the polyurethane which has good insulation efficiency.
