In Kerala market there are two types of solar water heater is available.   First is a flat plate collector with an insulated, weather-proofed box containing a dark absorber plate under one or more transparent or translucent covers. This is the most common type solar water heater. Murickens are manufacturing and marketing solar water heater in kerala . It is  tested and proved 30 years ago that it is the most suitable type for Kerala’s climatic conditions.

Second one is evacuated tube collectors which are made up of rows of parallel, transparent glass tubes. Each tube consists of a glass outer tube and an inner tube called absorber which covered with a selective coating. The demerits of this type are more chance of brakeage of tubes when it is exposed to sunlight, chance to catch fungus inside the tube and consequently lower the heat of water. 

Murickan’s Kerala flat plate solar device contains the solar collector panels, the working fluid (water), the storage tank .Special black or dark green coatings are used to absorb the energy .The heat absorbed by collector panels with size of 2 meter length and 1 meter width with 9 copper fins are used to heat water. When solar collectors are exposed to sun light, the water flowing through tubes in the panels is heated. .  Copper tubes transfer the collected heat to the water more effectively than aluminum, steel or glass tubes. The covering over the collector reduces the escape of collected heat to the outside air. The cover is transparent to short-wave solar radiation, but not to infrared radiation from the selective surface .The back and side insulation, typically R-value 12, reduces conduction losses.  Heated water from solar panel collects in a  storage tank which is specially designed to preserve the heat for long time
