Every solar water heater contains a solar collector. A solar collector is the portion of the water heater that collects the sun's rays and heats the water. Collectors can be affected by weather and location, so many different types of collectors exist to compensate for these conditions. Generally, solar collectors consist of glass or metal tubes that are heated by the sun. Water is pushed through the tubes, and the heat of the tubes is diffused through the water.
The GOBI line of solar flat-plate collectors is one of the industry’s highest-rated. Over 30 years of design and engineering refinement have gone into making it a world-class performer for heat output, efficiency, and durability. The collector is available in three sizes, with two surface types to choose from blue sputtered, and black paint (used in ideal climates like Hawaii only), making it suitable for all types of solar heating applications.
