pre-heated solar water heater with assistant tank
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 heat 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 via the copper coil . The copper coil is installed inside the tank as the heater exchanger.When water flows into the copper coil,it absorbs the heat of water in the tank . Therefore the water tank is just as a heat storage tank.so the hot water we use is actually from the copper coil, it is more clean,and even drinkable(as the copper can purify the water).The whole system also works at 0.2MPA.
Necessary parts: Tank( with a copper coil inside) ,the three-high vacuum tube,bracket,assistant tank
optional parts:
A controller:show water level, temparature for the conveince of cold water supply
An electric heater: when without sunshine ,in rainy days or winter days,etc. be used to heating water.

Bracket: SUS 202 BA 1.2mm-1.5mm; Angle: 38°/45°
Advantages:
1. The pre-heated solar water heater is adopted copper coil as the heat exchanger,(as the copper can purify the water),so it can supply hot water with high quality, clean and even drinkable.
2.And as copper coil transfer the heat rapidly,so it can ensure that the water is always hot.
