Solar Water Heating Systems
We are blessed with Solar Energy in abundance at no cost. The solar radiation incident on the surface of the earth can be conveniently utilized for the benefit of human society. One of the popular devices that harness the solar energy is solar hot water system (SHWS). Solar Hot Water System turns cold water into hot water with the help of sun’s rays.
A solar water heater consists of a collector to collect solar energy and an insulated storage tank to store hot water. The solar energy incident on the absorber panel coated with selected coating transfers the hat to the riser pipes underneath the absorber panel. The water passing through the risers get heated up and is delivered the storage tank. The re-circulation of the same water through absorber panel in the collector raises the temperature to 80 C (Maximum) in a good sunny day. The total system with solar collector, storage tank and pipelines is called solar hot water system.
Broadly, the solar water heating systems are of two categories one is Flat Panel Collector (FPC) also called Indirect heating system and second is called Evacuated Tube Collector (ETC) also called Direct Heating System. The SHW systems are economical, pollution free and easy for operation in warm countries like ours.
Flat Plate Collectors (FPC) based Solar Water Heaters
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. This kind of system is less effective because the problem of high hardness of water in some regions.
Evacuated Tube Collectors (ETC) based Solar Water Heaters
Evacuated Tube 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 heating is now a mature technology which is the most advanced and state of art technology in Solar Water heaters. The efficiency is more than in a flat plate solar water hater. ETC water heaters produce hot water even in winter / rainy days. The main part of ETC solar water heaters are a Stainless steel PUF insulated tank and Evacuated Glass tube collectors. The vacuum tubes are with different diameter and length according to applications. In pressurized systems heat pipes are used. Wide spread utilization of solar water heaters can reduce a significant portion of the conventional energy being used for heating water in homes, factories and other commercial and institutional establishments. Internationally the market for solar water heaters has expanded significantly during the last decade.
Suggested Uses of the United Solar Water Heating System
For Bathing Purposes
The water from the Solar Water Heater can be used directly for bathing purposes during winter or during cold days.
For Preheating Water for Cooking
For cooking purposes water can be pre heated by using the solar water heater, this reduces cooking gas bills by upto 60-80%.
For Making Tea / Coffee
The water from the Solar Water Heater may be sufficiently hot to directly make tea or coffee reducing electricity or gas bills up-to 50% to 70%.
For General Purpose Cleaning
Hot Water from the Solar Water Heater can be used to Clean toilets- Wash dishes- Wash clothes- Clean Floors etc.
Sterilization
Very useful in hospitals for sterilization use
Process Industries
For pre heating boiler water.
As we always like to say - "LET THE SUN PAY THE COST FOR YOU"
We recommend that you use the system as regularly and as much as possible, the more you use the system, the faster is the break even.

WHY ONE SHOULD GO FOR‘SOLAR WATER HEATING SYSTEM’
We can provide u a better service in future than other companies with the help of our trained staff. Our Complete SYSTEM including TANKS , STANDS and Manifold is manufactured in INDIA except at our factory in MOHALI. Therefore its not a cheap Chinese quality product. We are using Food grade Stainless Steel – SS304 (2B) for Hot Water Storage which makes the Hot Water from our tank completely safe for Cooking and even for direct Consumption.
SAVE ELECTRICITY- By installing per 100 LPD solar water heating system you can save upto 1500 units of electricity per year. Techno Commercial Analysis (Electricity)
(Sample Example)
Cost of 100 LPD Solar Water Heating System = Rs 22,000/-
One 100 LPD Solar Water Heater Saves about 1500 Units of Electricity per year
I.e. Rs 7500/ year (Electricity @ Rs 5.00/ unit *)
So a 100 LPD System shall save about Rs 7,500/-Year.

Solar Water Heaters
United Solar has introduced a wide range of water heaters with capacities varying from 100LPD to 10,000 LPD. The applications include domestic water heating, commercial establishments like hotels, hospitals, resorts, hostels etc.
Solar water heater produces hot water using energy from sunlight. Hot water is used for different applications, domestic as well as industrial. By using solar water heaters, we can save the electricity and in turn save a lot of money.
How It Works
Solar Water heater consists of mainly 2 parts. One is the collector and other is Insulated tank. The cold water in the collector get heated up and collected in the tank by thermo siphon principle. This circulation continue till the water in the tank heated up to 60-80° centigrade. The hot water in the tank remains hot for more than 24 hours.
Domestic Models : 100 LPD , 125 LPD, 200LPD, 250 LPD & 500 LPD (Litres per Day)
Industrial Models : above 500 LPD upto 10,000LPD
ETC Solar Water Heater
Evacuated Glass tubes used as the absorber in ETC Solar Water heaters. The ETC is having two tubes with vacuum between the tubes. The outer tube is transparent allowing light rays to pass through with minimal reflection. The inner tube is coated with a special selective coating (Al- N- Al) which features excellent solar radiation absorption and minimal reflection properties. The trapped heat inside the tube will not transferred to the outer tube because of vacuum.
