Newly pressurized solar water heater (hot sell)

pressurized solar water heater
1. High efficience performance
2. Certificate:CE,ISO,CCC
3. OEM provide and samples offer
compact pressurized solar water heater
Working Principle:
The heat pipe is hollow and evacuated, as same as the solar tube.There are a small quantity of purified water and some special additives in it.The heat pipe used in Qirui solar collectors has a low boiling point.Thus, when it is heated, the water vaporizes rapidly.The vapor rises to the top of the heat pipe and transfers heat.As the heat is lost at the top, the vapor condenses to form a liquid (water) and returns to the bottom of the heat pipe once again to repeat the process.
Features:
High efficiency solar collector using heat pipes and evacuated tubes.
- Able to be used in all climates.
- Copper heat pipes are applied for rapid heat transfer.
- Easy installation both on the roof and on the ground.
- Applied for main water pressure.
- 150mm pipe is applied in the inner tank for enough heat exchange.
- Patented connection design isolates copper heat pipe from stainless steel inner tank, greatly reducing the damage caused by galvanic corrosion.
Advantages:
1. Special high quality Insulated material to reduce the heat loss
2. Excellent workmanship to guarantee the decent appearance, change for your request
3. Long life span and easy operation
4. This type of solar water heater can work in high pressure
5. It uses the heat pipe which can deliver the heat rapidly
6. The vacuum tube will not break in the winter for there is no water in it, even in the coldest area
7. Each vacuum tube works individually, so the machine will still at work in the event of occasional vacuum tube break down
8. Hot water with pressure make you bathe more comfortable
