Solar Water Heater.
ETC (Tube) Based Solar Water Heater.
MG Rama Energy offers Evacuated Tube Based Solar Water Heating system for your hot water usage. There are two glass tubes which make single evacuated vacuum glass tube. The tubes are fused on one side and hermetically sealed with each other on the other side. The internal glass tube is coated with highly observing environmental friendly coating to trap the solar energy. The sunlight radiation falls on the glass tube passes through external glass tube and absorbed by the multi layer coating on internal glass tube and converted into heat. This heats up the water contained in the inner glass tube. The heated water is lighter than the normal water thus it starts rising through the tube. The effect is called 'Thermosyphon' (natural circulation) effect which let the water eventually travel towards the top storage tank. Simultaneously cold water from the tank descends to the tube, gets heated in the absorber and rises back to the tank. The cycle keeps repeating. The water retains its heat for a long time as the hot water storage tank is insulated to prevent heat loss.
MG Rama Solar Water Heating System consists of the following major components;
- Evacuated Solar Glass Tube Collector.
- Water Tank Stand.
- Other fitting accessories.
