Glassline – The future of water heating in India

The cold weather has already dawned upon us and nothing is more rejuvenating than a hot shower on chilly winter mornings. A good water heater is, therefore, a must-have companion for the winters. With the changing urban landscape, houses are expanding vertically thus creating the need for specialized water heating solution that can withstand high pressure and work with inconsistent water qualities.

Let us here understand the basic problems experienced with conventional water heaters with steel tank and no protective coating. The high salt and mineral contents in water make the inner tank not only corrodes the inner tank but also may lead to tank leakage and potential electrical hazard. Moreover, these tanks are just not capable of handling tremendous pressure that is a common thing in high-rise buildings.

Thankfully, technology has made sufficient advancement to efficaciously counter these problems. To prevent corrosion of water heater storage tanks, manufacturers are now lining the inner surface with enamel coating. Enamel coating also referred to as glassline coating, doesn’t corrode and can increase the lifespan of your water heaters many folds. But how well would it hold under high pressure?

Orient Electric uses Ultra Diamond Glassline technology in its water heaters that can withstand up to 8 bars of pressure, thus making them fit for use in high-rise buildings. The end result is an extremely durable water heater that shall last years without any hint of corrosion or scaling.

Orient Enamour and Zesto are two models with Ultra Diamond Glassline storage tanks that you can consider buying.
