Efficiency

Heating water is one of the biggest electricity costs in an Indian home, and small changes add up fast. Our Efficiency guides show you how to cut running costs without cold showers: the right thermostat setting, how tank insulation and pipe lagging reduce standby loss, and whether a timer, a higher star rating, or a solar water heater actually pays back for your usage. We explain how hard-water scale quietly wrecks efficiency, how to size a unit so you're not paying to heat water you never use, and how storage, instant, gas, and solar options compare on real running cost. Practical, numbers-first advice to get more hot water from every rupee.
