 Solar hot water system at L’Oreal`s factory in Pune Five years ago, French cosmetics giant L’Oreal commissioned one of the largest indirect solar water heating systems in India for its factory in Pune, located in the western part of the country. Each day, the fully automated and pressurised system heats up around 32 m3 of water to 55 OC in order to wash the plant’s process vessels. The total investment amounted to INR 7.5 million (EUR 115,000), which was paid back within four years. Its back-up system consists of a diesel-fired boiler.
