A 500 LPD solar water heater is not a household appliance decision, it is an infrastructure one. If you are running a joint family home, a small hostel, a PG, or a guest house where 10 to 15 people need hot water in the same two-hour window every morning, this is the capacity that keeps up. The Anu Solar water heater in this 500 litre configuration uses evacuated tube collector technology, with 34 tubes drawing heat from sunlight and transferring it into the tank, delivering hot water without adding a rupee to your electricity bill. An ETC solar water heater performs better than a flat plate system in early morning and cloudy conditions, which is exactly when a full house wants hot water.
It is built for hard water, which is what kills most water heaters in India. The inner tank is galvanised iron with Anu's Crystal Blue glass-lined coating at 1.6 mm thickness, rated to handle water hardness up to 2000 ppm. In Bangalore, Hyderabad, and across most of peninsular India, borewell water in that range destroys an ordinary tank within a few years. That GLC coating is why this unit carries a 10-year tank warranty, and the outer tank is galvanised and powder coated for weather protection. Suitable for a family of 10 to 15 people, the system holds 500 LPD across 34 evacuated tubes, with a galvanised iron inner tank at 1.6 mm thickness carrying the Crystal Blue glass line coating, a galvanised powder-coated outer tank, hard water tolerance up to 2000 ppm, and a 10-year warranty on the tank.
Check three things before you buy, because this is a large system and it will not suit every roof. Your terrace needs at least 8 feet by 9 feet of clear, unshaded space. Your overhead tank or Sintex must sit at least 6 feet above the terrace level, since this unit runs on gravity feed. And if you have a booster pump on your terrace, this model is not for you, you need a pressurized system instead. Tell our team your setup and we will confirm before you order, or point you to the right alternative. Transportation to your house, lifting to the terrace, and installation are all included in the price, and you arrange the plumbing connection.
SolarClue is India's managed solar marketplace, and we do not just list this heater. Our team confirms whether 500 LPD is the right size for your household and whether your terrace and tank height suit a non-pressurized ETC system, before you spend anything. You secure the order with a token payment rather than paying everything upfront. Delivery, terrace lifting, and installation are coordinated by us through verified partners, and we handle Anu Solar warranty support afterwards. Compare it against Supreme, Sudarshan Saur, V-Guard, and other 500 LPD systems on our platform, and buy the one that actually fits your roof.
