Working Principle

The working principle of pre-heating compact pressurized solar water heater.

Copper Coil Heat Exchanger Pre-heated Solar Water Heater DIY Trade in China

“Pre-heating” solar water heater provide mains pressure via a high efficiency copper coil heat exchanger which located in the tank.

1. For water in the main tank, principle is the same as the non-pressure solar water heaters:
All-glass evacuated tubes absorb and transfer sun energy into heat energy, then heat water in the vacuum tubes. Depend on the different density between the hot water and cold water; a cycle can be created in the tube which hot water ascending and cold water descending status. Keeping natural circulation like this, the water in the tank becomes hotter and hotter.

2. For water in the copper coil:
When cold water flows through the coil it absorbs heat from the water inside the pre-heating tank. And the water we actually use is the water in the copper coil, it means it is the fresh water (there is no pollution in the water).
