Sunny ‘Ecosol’ is a solar geyser developed especially for areas with soft water supply. This geyser comes with thick specially treated steel, SS 304 2B Storage tank, to withstand corrosive effects of chlorides in poor quality water and prevent tank leakage. This strong, robust tank enhances performance and life of the solar geyser.

Ecosol has been developed using Evacuated tubes as solar collectors (ETC). The Sol Series, consists of double glass tubes with the inner one coated with selective coating using sputtering techniques and then vacuum is created between the two tubes.

Advantages of Sunny Ecosol

High Grade digitally controlled PUF insulation

You get running hot water not only during the day, but also at night !! Our insulated hot water tank keeps the temperatures above 55 C even after sunset.

No Electric Shocks

You needn’t worry about kids in the bathroom, as there is no possibility of electric shocks, as is the case with electric heaters.

No Monthly Bills

There is negligible maintenance cost and NO monthly bills as compared to conventional geysers.

Pleasing Appearance

A Powder coated Aluminum body ensures a pleasing and long lasting system, as there is no corrosion and rusting.

Quick Payback

Think Solar Geysers are too expensive? Think again – our payback period is just 3 years.

Why NRG?

  • Renewable – Save on gas/electricity bill
  • Convenience – 24 X 7 Hot Water
  • ISI mark, GEDA, MNRE Approved
  • Tax benefit – 80% depreciation
  • Branded Quality Product
  • Service – Prompt & reliable
Tank: 50mm high density PUF Insulation

PUF is a very effective insulation material, much superior to the commonly used glass wool in solar geyser tanks. It prevents heat from going in or out. Infact most of the top class refrigerators like Whirlpool, BPL etc use PUF!

GI Pre coted Outer covering

Powder coating is an advanced method of applying a decorative and protective finish. The powder used for the process is a mixture of finely ground particles of pigment and resin, which is sprayed onto a surface to be coated. The charged powder particles adhere to the surfaces until heated and are fused into a smooth coating in a curing oven. The result is a uniform, durable, high-quality, and attractive finish. All our products are powder coated and
oven baked for the best results.
Powder coating is the fastest-growing finishing technology in North America, representing over 10% of all industrial finishing applications. We believe in providing you with, only the Best!
