I had purchased a Solar water heater from Anu Solar System Bangalore, after two years the , tank was leaking, I had contacted the Anu Solar System Bangalore , they have asked Rs 10, 000 for replacement of tank, the Anu Solar System Bangalore is not providing the proper tank and nor replacing the faulty tank, usually the solar water tank life is a about ten years, but this tank lasted only for two years .
I donot recommend for purchasing of solar water heater from ANU system Bangalore due to faulty service and bad product .
