Types of solar water heater


Different Types Of Solar Water Heaters
Two types of Solar Water Heaters are available; one based on flat plate collectors and the other based on evacuated  solar water heater price in Chennai tube collectors. Flat plate collector solar water heater price in Chennai (FPC) based systems are of metallic type and have longer life as compared to Evacuated tube collector (ETC) based system  solar water heater price in Chennai because ETCs are made of glass which are of fragile in nature.

Both these systems are available solar water heater price in Chennai with and without heat exchanger. They can also work with and without pump. Systems without pump are known  as solar water heater price in Chennai  thermosyphon systems and those with pump are known as forced circulation systems.


Type Of Solar Water Heater Suitable For Different Places/Category Of Users
ETC based systems solar water heater price in Chennai  are cheaper than FPC based system. They perform better in colder regions and avoid freezing problem during sub-zero temperature. FPC solar water heater price in Chennai  based systems also perform good with anti-freeze solution at sub zero temperature but their cost increases. In other regions, both perform equally good.

Systems working on thermosyphon  solar water heater price in Chennai principle are simple and relatively inexpensive. They are suitable for domestic and small institutional applications, provided solar water heater price in Chennai  water quality is good and it doesn’t have large chlorine contents. Forced circulation systems are generally preferred in industries or large establishments.



At places where water is hard and solar water heater price in Chennai have larger chlorine content, if FPC based system is being installed, it must be with heat exchanger as it will avoid scale solar water heater price in Chennai  deposition in copper tubes of solar collectors which can block the flow of water as well reduce its thermal performance. ETC based solar water heater price in Chennai  systems will not block the flow of water but its performance may go down due to deposition of salt contents on inner surface of glass tubes, which could be cleaned easily once in a year or so.
