Solar Water Heater

A Solar Water Heater is a system which provides hot water for bathing, washing, cleaning and etc. using solar energy. A Solar Water Heater comprises of an array of solar collectors to collect solar energy and an insulated storage tank to store hot water. Both are connected to each other. During the day time, water in solar collectors get heated which is either pumped or flown automatically on thermosyphon principle to the storage tank. Hot water then stored in the tank can be used for various applications. It is generally installed at the terrace or where sunlight is available and heats water during daytime which is stored in an insulated storage tank for use when required including mornings.


  Solar Water Heater-Evacuated Tube Collector (ETC) Type

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.


  • High quality tubes made from borosilicate glass
  • No clogging/choking
  • Long lasting
  • Better performance in winter and cloudy days
  • Inner coating of glass tubes consists of layers of copper, Nickel and aluminum nitride
  • Vacuum jacket insulation
  • Heats water to a very high temperature
  • Makes hot water available even on partially cloudy days
  • High quality PUF insulation for maintaining high temperature of water inside the tank
  • Compact and light weight water heater
  • Easy to install, operate and maintain
  • Works efficiently with hard water
  • SS 304 tank for hot water storage tank
  • Special coated MS stand
  • Unique reflector for high reflectivity
  • Safe and environment friendly

  Solar Water Heater-Flat Plate Collector (FPC) Type

The solar radiation is absorbed by Flat Plate Collectors which consist of an insulated outer metallic box covered on the top with toughened 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.
