Description:

Pre-heated solar water heater also relies on the natural circulation of water between the collector and the tank (that is tubes absorb solar energy, and heats the water inside the tube, hot water rises, cold water flows down).

It differs from compact non-pressurized solar water heater because it gets a copper coil inside the inner tank. The hot water rises from the tube into the tank, and heats the copper coil and finally heats the water inside the copper coil. Therefore the water tank is just as heat storage tank.

So the hot water we use is actually from the copper coil, it is cleaner and even drinkable (as the copper can purify the water).The whole system also works at 0.3MPA.

Necessary parts: Tank (with a copper coil inside), the three-high vacuum tube, bracket

optional parts:

A controller----show water level, temperature for the convenience of cold water supply

Assistant tank---fill water in time constantly.

An electrical heater---when without sunshine or in rainy days and winter days, use for heating water.

Features:

1.Instant heat exchange; plentiful warm water for use

2.Fresh water quality

3.Works with pressure

4.Output water temperature is stable, so it is very comfortable and safe to use.

5.Hot & cold water flow is separated.

6.Copper coil is tested and does not break; high grade materials are used

7.Works intelligently and reliable.
