The invention discloses a solar water heater having a pressure regulating function and adopting a semiconductor or optical energy for heating. A water tank (8) is manufactured from non-metallic materials in a blow-molding or injection molding or rotational molding mode, or is manufactured from metallic materials. A pressure regulator (12) is mounted on a water inlet pipeline of the water tank. The pressure regulator is composed of a shell (12-1), a piston (12-2), a cover (12-3) and a rubber part (12-4). The piston (12-2) can move in the shell (12-1) along with pressure changing in the water tank so as to decrease the opening degree of a water inlet or close the water inlet. 具有压力调节功能半导体或光能加热的太阳能热水器，水箱8由非金属材料吹塑或注塑或滚塑制造，或用金属材料制造，并在水箱的进水管路上装有压力调节器12；所述压力调节器由壳体12-1、活塞12-2、盖12-3、橡胶件12-4构成；活塞12-2会随着水箱内的压力变化，在壳体12-1内产生位移，关小甚至关闭进水口。
