Solar Water Heater

A revolutionary product form the house of V-Guard ,the brand that has always delivered the best in quality, technology, performance and service. The most advanced in Solar Water Heaters, V-Guard Solar Water Heaters are made from high-quality components and come with international technology. The Evacuated Tube Collector System facilitates high-efficiency absorption and utilization of solar energy, with minimum heat loss. V-Guard Solar Water Heater saves a substantial amount on electricity bills and other fuels, making it a worthy investment for a lifetime.

Working Principle

Sunlight, Incident on the vacuum tube, passes through the outer transparent glass tube and strikes the outer surface of the inner glass tube wity selective coating (A/N/SS/CU). This glass tube, which act like a black body, absorps the radiation and gets heated up in the process. The presence of vacuum between the two tube prevents heat loss to the surroundings. The heated inner tube transfers this heat to the water which it is directly in contact. Hot water is lower in density and therefore has a tendancy to rise up.Cool water from tank flows down to replace the hot water, faciliating circulation by thermosyphon. And through this process, the entire water in the storage tank heats up and ready for use. The storage tank is insulated with PUF which minimises the heat loss at night.

Features of V-Guard Evacuated Tube Collector System

  • Generates hot water without electricity or any other fuel.
  • High quality vacuum tubes made from Borosilicate minimize heat loss.
  • Negligible scaling of tube.
  • SS 304L (Jindal Steel) tank with Aluminium/Stainless Steel/ MSPowder Coated cladding.
  • High quality PUF insulation minimizes the heat loss of water inside the tank.
  • Greater absorption area, auto sun tracking due to circular shape of vacume tubes.
  • Efficient performance in winter and partially cloudy days.
  • ISI Electric back up heater (optional to the customer)
  • Compact size, low height, light weight. Easy to install and transport.
