Solar water heaters use natural sun light to heat water. This system works on the thermosiphon principle and is designed to provide hot water without consuming expensive electricity. This is the most effective way to generate hot water thereby saving costly power and is also environment friendly. The extra thick SS inner tank & high density PUF insulation makes owning the Havells Solero a superior choice ensuring years of trouble free hot water for you and your family. The system installed on a terrace or open space where it can get sunlight and the energy from the sun is then used to heat water and store it in an insulated tank. The system is not connected to electricity supply and thus does not have an on-off switch, but it uses the sunlight throughout the day to heat the water and store it in the storage tank. When there is insufficient sunlight, the water is preheated and a back-up system takes over to bring the water to the required temperature. This system can be used at a constant temperature throughout the year.
