The Supreme Heavy Plus 165 LPD ETC Solar Water Heater is an evacuated tube system with an enamel-steel glass-lined tank, sized for a family of 3 to 4, carrying a 20-year tank warranty. It uses 16 tubes (1800mm each) to heat a 165 litre tank rated to handle water hardness up to 2000 ppm. It is a gravity-fed, non-pressurized system.
A 20-year warranty is the longest cover available. Most solar water heaters guarantee the tank for 5 to 10 years; a few reach 15. Twenty years is a claim only a genuinely durable tank supports, and here it is backed by the construction: enamel steel with a glass-lined coating at 2.5mm thicker than the 1.6mm typical of the market, and enamel steel rather than plain galvanised iron. Together with the 2000 ppm hard-water rating, this is a heater built to outlast most of what surrounds it. If you are buying once and want it to last two decades, that combination is the reason to choose it.
Built for hard water. On borewell supply, where mineral-heavy water destroys an ordinary tank in three to four years, the glass-lined enamel construction and 2000 ppm rating are what let this unit carry a 20-year guarantee where a plain tank would fail early. Across the water heaters we stock, only Sudarshan Saur's glass-lined range and our own Varistor ETC match this hardness rating most V-Guard and Racold models handle 600 to 1000 ppm.
Evacuated tube heating. The 16 evacuated tubes, each 1800mm long, hold a vacuum layer that traps heat like a thermos, so the system keeps producing on cold winter mornings and overcast monsoon days when a flat plate system slows. For a family of 3 to 4 bathing early, that keeps hot water available for everyone.
A very compact footprint. This unit needs only 8 feet by 3 feet of clear terrace space among the smallest at this capacity, which helps on a rooftop that also carries tanks and other equipment.
Two things to confirm before ordering. Your overhead tank or Sintex must sit at least 6 feet above terrace level, because this system runs on gravity. And if you have a booster pump on your terrace, this product is not for you — you need a pressurized model instead. Send our team a photo of your terrace and we will confirm before you spend anything.
On sizing, 165 litres serves 3 to 4 people. Five or more, step up to a larger capacity; two or three, a smaller unit saves money.
The price includes transportation to your house, lifting to the terrace, and installation. You arrange the plumbing and electrical wiring.
SolarClue is India's managed solar marketplace. Our team confirms whether 165 LPD suits your family, whether your water hardness suits this tank, and whether your terrace and tank height work for a gravity-fed system, before you pay anything. You book with a token payment rather than the full amount upfront. Delivery, terrace lifting and installation are coordinated by us through verified partners, and we handle Supreme warranty support afterwards. Compare the Supreme against Sudarshan Saur, V-Guard, Anu and Racold on our platform, and check the current supreme solar water heater price.
