Sunstream GV uses stainless steel 304 for the inner tank and is 0.8 mm thick – sufficiently thick for soft water conditions up to 200 parts per million (ppm). The outer tank is made of stainless steel 430, and gives the product an excellent look and finish..
Our Sunstream systems are manufactured in-house, and tailored to our customer needs: whether hard or soft water, pressurized or non-pressurized systems, stainless steel or mild steel tank, evacuated glass tube or copper flat plate collectors.
Sunstream GV belongs to our class of products known as Sunstream G. ‘G’ stands for glass – as in evacuated glass tubes. Orb uses big 58mm glass tubes to heat water from 25 to 65 degrees in just 4.5 hours (assuming an average sunny day in India).
Compared to using electricity, Sunstream GV systems save customers a lot of money. The average daily cost of a Sunstream system using evacuated glass tubes is Rs 12 (USD 0.24 cents). The average daily cost of an electric geyser is nearly twice that, at Rs 21 (USD 0.42 cents).
The customer can also opt for a back-up coil to be inserted in their system for hot water even during extended cloudy weather..
