What are the types of Solar Water Heater?
Solar Water Heaters are classified as Flat Plate Collectors (FPC) and Evacuated Tube Collectors (ETC) Solar Water Heater:
1. Flat Plate Collectors (FPC) Solar Water Heater:
In Flat Plate Collectors Solar Water Heater, the solar radiation is absorbed by flat plate collectors which consist of an insulated outer metallic box covered on the top with glass sheet. Inside there are blackened metallic absorber (selectively coated) sheets with built in channels or riser tubes to carry water. The absorber absorbs the solar radiation and transfers the heat to the flowing water. The FPC solar water heaters have better performance in hot climatic conditions. The FPC type solar water heater can withstand higher pressure. FPC heaters have highest durability. They can last for more than 15 years without maintenance.
2. Evacuated Tube Collectors (ETC) Solar Water Heater:
The evacuated tube collector of Evacuated Tube Collectors (ETC) Solar Water Heater is made of double layer borosilicate glass tubes evacuated for providing insulation. The outer wall of the inner tube is coated with selective absorbing material. This helps absorption of solar radiation and transfers the heat to the water which flows through the inner tube. The ETC solar water heaters have better performance in cold climatic conditions. ETC type solar water heater can perform well even in cloudy days. ETC heaters have lower heat loss at night as the vacuum inside the tubes offers better insulation. ETC heaters have highest durability. They can last for more than 5 years without maintenance. Corrosion is not an issue in case of ETC as it is made of glass.
