1,The Principium for Direct-Plug Solar System by man-hand

Glass vacuum tubes absord energy from sunlight, and transfer the sunlight thermal to water in tubes , then the water temperature go up and hot water rise to tank , cold water in tank go down , circulation like so one day , the cold water in Tank become hot water, when the tank is empty , the user should open the valve to let the cold water fill the tank , when overflow have cold water go out ,which means the tank is full,then user close the valve.

2,the Principium for Direct-plug solar system with accessorial tank

Glass vacuum tubes absorb energyfrom sunlight. Which heats the water of vacuum pipe. This process leeds to the water's consistency decrease, hot water is going up, floating at the top of the water tank and the cold water is going down. Frequency circulation makes the water temperature increase. When using hot water, the water level in the water tank is going down, ball cock in the accessorial water is opened and the cold water inflow

3,The principium for Direct-Plug Solar System with controller

Driving electromagnetic valve by using control, then filling water into the water tank. Glass vacuum tube absorbs the sun's energy, which makes the water heating of the water tank . The controller start the electrict heating, which makes the water heating in the tank for the preperation when it often rains

4,the pincipium for Direct-Plug solar system with pressure boost pump

All Direct-plug Solar water heater installation is limited by height , it must be installed on high place like roof , so as to make it have pressure , if there are no high place , we should use pressure boost pump so that we may install the system on ground and use hot water on the height ***0meter and the hot water pressure can be same as the cold water pressure.

Direct-plug Solar water heater types
Features:
A: Water tank: Import color steel
B: Inner: Food Grade Stainless Steel
C: Bracket: aluminum alloy or steel bracket
D: The structure is stable
F: different angle installation
