Solar water heater is one of the renewable source of house hold equipmen which is in use since many years. as the system get older it get subjected to changes and performance get dimished. the slides here shows some of the preventive measures to be taken under two worse situation - corrosion and freezing

1. Preventive Measures For
Corrosion, And Freezing In Solar
Water Heater

2. Solar Power
• Solar is one of the renewable energy sources which can
easily energize the household equipment with its simple
apparatus.
• The solar is one if the affordable energy source seen
implemented since many years ago in the calculator,
watches, etc…
• There are many power plants which is been constructed
and operated by utilizing the sun’s
radiation.http://www.slideshare.net/leeshin12/solar-

3. Solar Water Heater
• This is one such equipment which is been in use since many
years ago.
• The water heater in here is powered by solar power.
• The water is made to flow inside the collectors and the
heat gets exchanged between the cold water and the heat
exchanger and forms converts them into hot water.
• This is how the solar water heating process takes place

5. Preventive Measures
• Though the installation and the construction process of
solar water heaters rely on the hand of the professional
contractors, it is the responsibility lies in the individual to
inspect for the flows in the system and maintain it.
• If the situation become worse, a professional should be
hired for which more money to be spent and seldom the
system replacement may also happens.

6. Corrosion
• Corrosion is the main problem which occurs frequently
and this is the alarming signal that the system is getting
old.
• Thus as the next step, folks should double the effort of
the cleaning process in even more professional way.
• Cleaning and maintaining of the solar water heater is
very easy process. some are mention below uniquely
to the problem called “corrotion”

8. Coating
• Coating process cannot be done by the fellow men, this
phenomenon purely depends on the professional heater
manufactures.
• Corrosion can occur at any part of the heater like tank,
collector, exchanger, etc…
• Thus proper coating should be given to all the parts and
it should be checked for the quality before purchasing.
• Double coated heaters are always the preferable factor.

9. Freezing
• Freezing is due to the temperature change when they cross
certain limit.
• This freezing will interrupt the water flow slowly making the
dews in the solar water heater as snows.
• Such situation is predominant in the area of high snow fall
region.
• This will happen when the system is left wet during the winter
season.
• Below are preventive measures for “Freezing”

10. Anti freezing agents
• This is one of the preventive measures to avoid the freezing
in the solar water heating system.
• The anti-freezing agents should be made to flow along the
path of the water which then melts the freezing in of the
system.
• Glycol is one such reagent which is used in large run.

12. Draining method
• There is huge common sense behind the usage of water
heater is that they are of no use during the summer
season, so it is always wise to drain them thoroughly and
make them ready for the upcoming stormy summer.
• Else the updates drain back system is used which drains the
water into the tank when the sunlight begin to diminish
and the temperature falls below certain limit

13. • These are some of the major problem occurs in all
the solar water heating system.
• The maintenance cost of this system costs more, thus
the maintenance should be done.
• Some of the maintenance tips are mentioned below

and-maintain-solar-water-heaters

14. • Glazerindia (http://glazerindia.com) is one of the
solar water heater producers In India.
• They provide number of solar water heaters of all
types like domestic solar water heater, industrial
solar water heater, commercial solar water heater.
