Pressurized solar water heaters, including solar thermal energy storage water tank, electric water tanks, plumbing, recycling water pipes, pumps, thermocouples and control meter panle, etc. Set up inside pressure hot water storage tanks, cold water pressure tank the bottom of the tube then , into the hot water pipes take pressure tank top and electric water tanks, the tanks out of hot water heating pipes then on the next cycle of water pressure tanks and electric water tanks at the bottom of the upper part, the pump located in the cycle of water on the thermocouple located in the pressure tank and electric water tank and three combined heat pipes, pumps, thermocouples, etc. connected with the control panel. The solar water heater system can realize temperature stable, antifreeze, reducing energy consumption, reduce scaling, layout flexibility, and so effectiveness.
