Non-pressure solar water heater

Product Description

The evacuated tubes have two layers of glass tubes, the inner tube absorb solar radiation then convert into heat energy and transfer it to the water in inner tubes. As we know, the density of water in different temperature is different, so the hot water circulates to the manifold, cold water in manifold flowing into tubes, through this natural circulation, the water will be heated. We can design pipes, pumps, connected collectors to water tanks, then water in water in water tank will be heated.

BTE Advantages:
1.       The material of inner manifold is SUS**4 2B, good function of anticorrosion and long working life;
2.       The material of outer manifold is hot galvanized sheet steel with plastics-prayed surface, beautiful and durable;
3.       The insulation material of manifold is polyurethane, keep energy in long time;
4.       High quality evacuated tubes with triple layer selective absorber coating, vacuum degree≤5.2x*0*4Pa, absorbing efficiency≥*2.5%;
5.       Full automatic production line can realize your different requirements;
6.       Working life≥*0years.
