Pressurized Solar Water Heater Features:                                          

1. pipeline is made of all red copper and conducted by heat transfer medium liquid;

2. back up with electric heater so that in the day without sunshine hot water can also  be used;

3. the tank inside the building, the hot water  loses less energy than the normal one;

4. with anode magnesium bar to prevent furring;

5. the pressurized solar water heater collector and the water tank is separated, that makes the system combine with the building perfectly;

6. it can be used for other function, such as warming. 

Pressurized Type Working principle:                                                       

1. The collector absorbs solar energy and transmits it to the water tank through circulation. 

2.When the temperature of the collector reaches the set value, the controller starts the circulation pump automatically. 

3. The circulation pump makes heat-conducting liquid circulate automatically. 

4.The heat-conducting liquid transfers heat to water by lower heat exchanger in the water tank. 

5.When the temperature difference between solar collector and tank doesn't reach the set value, the circulation pump will be shut automatically. 

6. In case the temperature of the water tank does not reach T max, Electric Heating Element will start to work automatically.

 Attention to installation                                                           


  •  Clearance of remains and sundries in water tank should be done ahead of installation in the purpose of avoiding walling up in or out vents, which may make water tank split up or deflated.
  • Do not load water when it is suuny. Better to load water at night or early in the morning expecially for the new unit. As the temperature of vacuum tube can reach 270°C at the highest. When water flowing at this time, vacuum tubes will be broken. 
  •  When loading water at a high water level, do not turn on the inlet valve openly but let water flow slowly to the tank, or the inner tank will be broken due to the expansion of high pressure.
  •  It is inappropriate to load water at a low water level, which will result in hot water in the tank reflowing to water pipe
  • Before having a bath, it is necessary to avoid scalding with hand to testing the temperature of water.
  •  If electrical heater is installed, it should be cut off when you shower.
