Pressurized solar water heating system,copper coil heat exchanger

Specifications

Features:

1. Stable and reliable performance and well wind resistance.

2. Vacuum heat-collecting tubes at high temperature.

3. It can withstand pressure of tap water when it works, and copper coil in tank bear pressure.

4. Use in any time: it adopts advanced design idea and integrates with high efficiency preheated patent technique. So it can warm the cold water rapidly when it flows through special pipe. It can overcome the short of traditional solar water heater, such as slow heating, long waiting time.

5. More capacity: we adopt special exchanging heat mode, it avoids mixed effect. So cold water can be heated at any time.

6. Economical and environmental protecting: there is no pollution when it is working since it depends on sunshine, green and economical.

7. Easy operation: it can supply water automatically, you can take it easy and enjoy good time.

Working Principle of  Pre-heating sun water heater:

   Vacuum tube collector absorbs sunshine to heat the water in tank. The water in tank is not for using but for heat preservation.  When needing hot water, the cold water flows through inlet, copper coil in tank absorbs heat from heated water in tank  then transfer to the cold water, so that temperature rise up ceaselessly.The water temperature of the outlet is closed to the water in inner tank (difference within 3 degree centigrade
