Abstract

A pressurized solar water heater. The water heater includes a water storage tank and a solar heat collection device. The solar heat collection device includes a lateral heat collector and longitudinal header. One end of the heat collector is connected with the header, forming a first heat exchange circulating loop; the header is installed at an angle to vertical and has a U-shaped heat exchange tube with two branch lines inside. The U-shaped heat exchange tube is also at an angle to vertical along with the header, and the two branch lines are at a high position and a low position respectively. The two branch lines extend upward and are connected with corresponding circulation connections of the water storage tank, forming a second heat exchange circulating loop.
