Sunstream GCC solar water heating system uses mild steel for both outer and inner tank and receives a ceramic coating on inner side of the inner tank for extra protection against hard water. The tank is also made extra thick – 1.5mm – so it can also handle hard water up to 1500 parts per million (ppm). As our lowest priced solar water heating system, it is excellent value for money.
Our Sunstream solar water heating 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 GCC 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 that heat water from 25 to 65 degrees in just 4.5 hours (assuming an average sunny day in India). ‘CC’ stands for ceramic & coated – the inner tank of Sunstream G comes with specially coated ceramic to with stand hard water beyond 1500 PPM and also increases the life of the tank. The outer tank comes with coated steel.
Compared to using electricity, Sunstream GCC 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 Sunstream GCC system for hot water even during extended cloudy weather .
