In 1936, A. O. Smith developed and patented a process to glass-line water heaters. Over the years, A. O. Smith has gained the respect and support of homeowners, contractors, architects and specifying engineers in over 60 countries by providing innovative energy efficient products designed for years of trouble-free service. A. O. Smith Water Heaters are very well designed products with the outer cover manufactured to give it high gloss, sheen and finish. Most water heaters in India don't have any colour options. Only A. O. Smith offers you the A. O. Smith ColourMatch System®. The system allows you to match the colour of your water heater to the colour of your bathroom. A. O. Smith Water Heaters come in white or ivory outer jackets with decorative front panels of the same colour. These can easily be changed to any of the eight different colour options. Geyser can be connected to any tap with the flexible union, or if the inlet and outlet pipes are connected to the angle valves provided for a storage geyser, it assumes the function of a storage geyser for delivering hot water in the taps, showers, washbasins or sink round the clock.
