Stainless Steel Solar Water Heater.

Non-pressured solar water heaterWater Tank:1,SUS304-2B Inner tank2,Polyurethane foam insulation3,Stainless or aluminum support 4,Trivalent element evacuated tube5,Electromagnetism or ball valve(optional)6,Electrical boost heater (optional)

Working principle:.1,The high quality vacuum tubed absorb the solar autraviolet ray,then heat the cold water in the vacuum tube2,The hot water rise in the top of the water tank ,and the cold water sink  to bottom then heat by solar collector.So the whole system is always circilating continuously3,The electromagnetism or ball valve can perform the water supply automatically,the water in the tank is not sufficient,the electromagnetism valve will open its valve,the tap water flow in the water tank,if the water is full,it will close the valve automatically

Feature:The A8-2 type has the stainless shell,so it can be used in the acid rain area,the A8-1 has aluminum alloy,the support is very light,Besides,it has 15years long life span,and the vacuum tubes can work individually,so if the only one of them can't work ,it won't influence on the others.The spare parts can be changed freely,it is suitable for the many resident buildings.

Non Pressure Water Heater Working Principle

The vacuum tube absorbs the sun’s rays and turns it into heat energy, heating the water in the tubes. As the temperature of the 

water rises it becomes less dense, so the hot water in the tubes float into the tank, and the cold 

water in the tank travels down into the tubes. This natural cycle keeps repeating and the water in 

the tank gets hot. This unit will work below freezing temperatures as the glass tubes are sealed 

and heat can only enter and not escape from them. Non pressure system drains by gravity, unit 

must be placed at high place above supply line

We can make the models for customer's order.So if you ask for special size please let us know.We could also provide the pressurized tank,the circulating pump,the controller and the expansion tank for favorable price.
