Solar Water Heater - The Cheap and Best !!!

Our range of solar water heaters includes Evacuated Tube Collector (ETC) and Flat Plate Collector (FPC) types. Rugged but beautifully crafted water heaters offer a trouble free, no maintenance, long lasting performance for years.

Working Principle...

Solar water heaters transfers the atmospheric temperature to the water stored inside the tank. The phenomenon is called “Thermosiphoning’. So, no coils, no gas, no electricity or any sort external artificial methods to heat the water. Want to learn more…Click here….

Solar Water Heater Types...

Evacuated Tube Collector - (ETC)

  • Triple Layer Coated Borosilicate Glass tubes (ALN/AIN-SS/Cu)
  • SS 304 Grade SS Inner Tank – 0.80 mm thick
  • Aluminium / SS (430 Grade)  outer tank
  • High Quality PUF insulation
  • Double layer tubes with vacuum to prevent heat loss
  • Back up heating coil ready
  • “Zero” maintenance cost
  • Energy savings of minimum Rs.11,000/- per year
  • No mechanical parts
  • Electricity not required (If heating coil (Optional) is not installed)
  • Powder coated strong structure to hold the tank and tubes
  • Stainless Steel Fasteners

Flat Plate Collector - (FPC)

  • Pure copper pipes for water circulation
  • Black colored alloy fins for better energy conduction
  • Strong aluminium structure for durability
  • SS 304 Grade SS Inner Tank – 0.80 mm thick
  • Aluminium / SS (430 Grade)  outer tank
  • “Zero” maintenance required
  • No mechanical parts
  • High quality PUF insulation to prevent heat loss
  • High quality glass surface to prevent impurities
  • Back up heating coil ready
  • Electricity not required (If heating coil (Optional) is not installed)
  • Hand crafted with beautiful colour coding
  • Powder coated strong structure to hold the tank and tubes
  • Stainless steel fasteners

Pressurized systems

We have solar water heaters specifically designed for sites where a pressure pump is installed. Heavy duty insulated tanks to withstand pressure generated.

Which one is the best for me? ETC or FPC

Of course, ETC the evacuated tube collector type is the cheap solution. Flat plate collector type (FPC – solar panel look a like) will cost double than ETC. The functionality of both the systems remains the same. Below, you can find certain factors that may determine which one is good for you.

1. Price

2. Durability

3. Maintenance

4. Ease of installation

5. Space required for installation

1. Price

                The main factor that determines the  price of solar water heaters is the method used in it to transfer the atmospheric temperature. If it uses Evacuated tubes instead of flat plates, then the price will be almost half. Since, any of these two can serve the purpose, the selection depends on your budget.

2. Durability

                Both the systems have a good life expectancy. But, the tube type has a high risk of breakage. If something falls over the tube or if you try to fill the empty tank when the tubes were hot, the tubes may blast and it cannot be used at all. Whereas, the FPC (Panel) type, has a glass shield to cover the copper tubes, can perform even the glass is broken. When you consider these factors, the durability will be on the higher side for FPC systems.

3. Maintenance

                Both the systems are install and forget type. But, since it is exposed to varying weather conditions, algae may accumulate over the tubes of the ETC type. This may eventually reduce the hot water generation capability. A wet cotton cloth is enough to wipe it out. But, you may have to do it once in a year. FPC type doesn’t have such an issue. 

4. Ease of installation

               In an FPC model, the panel is slightly heavy. It may be difficult to lift it up to the top and install it. But tubes can be moved one by one and can be installed easily.

5. Space required for installation

               The space required for the Installation of eithr of these two types is almost the same.
