Section II
Solar water heaters
UTILISE THE NATURESOLAR ENERGY CAN BE USED TO HEAT THE WATER
SOLAR WATER HEATERS
A solar water heater Collects solar energy through a collector Store water in an insulated tank Based on the collector system, solar water heaters can be of two typesNo.1 Solar water heaters based on Flat plate Collectors Solar radiation is absorbed by flat plate collectors. It consist of an insulated outer metallic box covered on the top with glass sheet. Inside there are 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.
Flat plate Collectors
Evacuated Tube Collectors
Collector 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.
Solar water heaters based on Evacuated Tube Collectors
Application Solar water heaters of 100-500 litres capacity are suited for Inspection quarters Larger systems can be used in training centre hostel etc. Hot water at 60-70 C can be obtained .

A case study for the IQ @ TE,Katpadi Heater used in IQ each 2 KW capacity
4 ( One per IQ)
Heater is On from Morning 6.30AM to 8.30 AM and evening 7.00 PM to 9.00 PM I.e 4 Hrs
Power consumption 4 Nos.x 4 hrs x 2000 watts
32 units /day
Energy consumption cost @5.00 / unit
Rs 160/ day
Capital investment for 500 ltrs SWH I/c all accessories
RS 143500
pay back period = Capital cost/Energy consumption cost
RS 143500/160 =897 days
PAY BACK PERIOD 2 years and 6 months
Solar water heating system practically requires NIL maintenance and life period is approximately 15 Years whereas water heaters require periodical maintenance of replacement of elements etc. and life period is approximately 7 years ,which further reduces the payback period
Savings after the pay back period / year is
365 x 160 = Rs 58400/-
A case study for the officers’ Hostel @ RGM TTC,Chennai(Already implemented)
Heater in each room 1.5 KW capacity
25 ( One per room)
Heater is On from Morning 6.00AM to 8.30 AM and evening 6.30 PM to 8.00 PM I.e 4 Hrs
Power consumption 25 Nos.x 4 hrs x 1500 watts
150 units /day
Energy consumption cost @6.50 / unit
Rs 975/day
assuming that hostel occupied for 250 days in a year cost of energy
Rs 243750/year
Capital investment for 2 nos.500 ltrs SWH I/c all accessories
RS 152000
pay back period = Capital cost/Energy consumption cost
8 months
A case study for the officers’ Hostel @ RGM TTC,Chennai ( contd…)
• Above system was commissioned during July 2004
• Savings to the BSNL achieved till date
= 3 years – 8 months( pay back period)
= 2 years 4 months x 2.437 lakhs (savings per year)
= 5.7 lakhs

Conclusion
SELF MOTIVATION
Let us motivate ourselves to conserve energy by which BSNL can cut down expenditure on energy front. Let us follow the words of our great poet / economist THIRUVALLUVAR, which go as follows
means, “There is no problem in path of income being small, but expenditure should not be wide.”
It is possible when the mind turns towards ENERGY CONSERVATIONCONSERVATION and extend your
hands to SWITCH OFF.
We need Everybody’s co-operation to conserve energy which put ourselves in right path and our
beloved BSNL too.
Long live BSNL!!
