Compact Pressurized Solar Water Heater
All the parts of compact pressurized solar water heater are same as non pressure solar water heater, except adding a heat exchanger copper coil inside big tank. When cold water flows into the copper coil, it absorbs the heat of the water in big tank via the copper coil, to get hot water. With the heat pipe in the vacuum tube, no water in the tube, each tube can work alone, the solar collector can work even one tube is broken.
High pressure solar water heater is a type of solar water heater which adopts advanced heat pipe and glass vacuum tube technology. High efficiency vacuum tube absorbs heat from sunlight and heat pipe transfer the heat to the condenser which directly contact with water in the solar water tank and it heats water by releasing heat gained from vacuum tube.
