Pre-Heated Solar Water Heater

Pre-heated solar water heater combines the advantages of Non-pressure solar water heater and Separated pressurized solar water heater together. Frankly speaking, the system is put a copper coil inside the Non-pressure solar water heater water tank, this product improves the problems of traditional solar water heater as limited hot water volume, long heat time, few out water, the worse water quality and so on. The "twice heat exchange" technology makes the high temperature, high efficiency and fast & large amount hot water circulation come true.

Working principle:

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 and even drinkable (as the copper can purify the water).

Features：

1) Copper coil as twice heat exchanger makes a pressurized and instant solar water heating system, tap water connects directly with copper coil for continuing water supply.

2) An assistant tank can be equipped for storage water tank refill and makes it a completely automatic running system

3）Suitable to use in all kinds of climates with electric heater

4）Absorbing heat quickly

5）It can withstand pressure of tap water when it works

6）Multifunction: Bathing, washing, domestic heating

7）Simple structure, easy plug-in installation.

8）Can be operated completely automatic if connect with intelligent controller

9）Be used in area widely
