Widely use non-pressure collector vacuum tube solar water tank heater
(1) Product Description

The Flat Collector System is shaped like a relatively large box, generally placed on the roof of the house. Inside the box contains a clear glass plate under which there is a heat-absorbing plate. The water or liquid to be heated passes through the pipes located under the heat-absorbing plate. The heat-absorbing plate is wrapped by an insulating layer to prevent heat from escaping, but this insulation system is not optimal because heat is very easily carried out by weather factors.

The most contemporary invention in the 21st century is solar water tank heater with a heat-absorbing collector. The highly sensitive (fast) vacuum tube solar water tank heater absorbs heat and is very efficient at storing heat. The vacuum tube consists of two glass tubes that form a layer. The inner tube is lined with the best absorbent layer which absorbs solar energy perfectly and resists heat dissipation. Between the two layers, a vacuum is formed, which minimizes heat dissipation. These tubes perform very well in all weather conditions even during cloudy and low temperatures (snow). This tube is made of 100% borosilicate (pyrex) glass. The heat absorption in the vacuum tube solar water tank heater is received by radiation. Thus, the percentage of heat loss is very small.

We recommend a solar water tank heater with the Latest Technology System, namely Vacuum Tube Technology which is very well known in Europe and America.
