Mayura's solar water heaters use a high-energy absorption vacuum tube that is over 1800 mm in length. This solar water heating system is designed keeping international standards in mind for optimum energy absorption and high efficiency. This solar water heater has a tank that comes with a 5-year warranty assuring a dependable service.

The principle behind solar vacuum tubes is simple. A solar vacuum tube works similar in design to a coffee thermos. It consists of a two layers of glass with a vacuum in between the layers. The outer layer of the solar tube is Borosilicate glass which is very low in iron and allows 98% of light energy to pass through. The 2nd inner layer has very special coatings applied to it.

The Mayura solar vacuum tubes use a patented 3-Layer process that results in a coating that can absorb more of the sun's energy while being able to withstand temperatures in excess of 300 degrees (575 F) without deteriorating.

The absorbed solar radiation is then transferred to a heat transfer fluid with in the tube (liquid inside the thermos), This liquid quickly heats up and rises to the top. In an open vacuum tube system the potable water is heated directly with in the vacuum tube. Thermosiphon causes the hot water to rise and be replaced by colder water. The hot water is the collected in the top collection chamber and pumped though the system.

• Higher temperature than FPC(Flat panel collector) System.

• Quick result in rainy and cloudy atmosphere.

• No need to service for long time.

• Easy to get temperature in hard water.

• Widely accepted in cold countries.

• Cheaper than FPC system

• No clogging or choking of water flow.
