A solar geyser, also known as a solar water heater, is a type of water heating system that uses the sun’s energy to heat water for domestic or commercial use. It is an environmentally friendly and cost-effective alternative to traditional water heaters that rely on electricity, gas, or fossil fuels.

There are several types of solar geysers available on the market, but they all work on the same basic principle: solar collectors absorb the sun’s energy and transfer it to a storage tank, where the water is heated and stored until needed. Here is an in-depth look at the different types of solar geysers and their features:

1. Flat Plate Collectors: Flat plate collectors are the most common type of solar collectors used in solar geysers. They consist of a flat, rectangular box with a dark-colored absorber plate and a transparent cover. The absorber plate is usually made of copper or aluminum and is coated with a selective coating that absorbs and retains heat from the sun’s rays. Flat plate collectors are suitable for moderate to low-temperature applications and are most effective in areas with high solar radiation.

2. Evacuated Tube Collectors: Evacuated tube collectors are a more efficient type of solar collector than flat plate collectors. They consist of a series of glass tubes containing a vacuum, which minimizes heat loss. Each tube contains an absorber plate that absorbs the sun’s energy and transfers it to a heat pipe, which carries the heat to a manifold, where it is transferred to the storage tank. Evacuated tube collectors are suitable for high-temperature applications and are most effective in areas with low solar radiation.

3. Integral Collector Storage Systems (ICSS): ICSS, also known as batch collectors, are a type of solar geyser that combines the collector and storage tank into a single unit. The storage tank is usually made of insulated metal or plastic and is located on the roof. The collector is a glazed box that is mounted on top of the storage tank and contains a series of copper pipes that carry the water through the collector. ICSS are suitable for moderate to low-temperature applications and are most effective in areas with high solar radiation.
