Product Introduction

Pre-heated pressurized solar water heaters working principle

“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).

Advantages

1. Use the copper coil as the heat exchanger, according with international fashion trend, it is simple to install and use.
2. It takes the advantage of the tap water’s pressure, more pressure, more comfortable.
3. It can produce hot water with constant temperature, safe and comfortable to use.
4. The water can be heated rapidly, so it can produce the high quality hot water.
5. It can produce more hot water than the general types because it isn’t restricted by the volume of the tank.
6. With the assistant tank, cold water adds automatically.
7. The water you actually use is the water in the copper coil, it means it is the fresh water (there is no pollution in the water)
