The Supreme Heavy Plus 270 LPD ETC Solar Water Heater is an evacuated tube system with a porcelain-enamel-coated CRCA steel tank, sized for a family of 6 to 7, carrying a 20-year tank warranty. It uses 26 tubes to heat a 270 litre tank rated to handle water hardness up to 2000 ppm. It is a gravity-fed, non-pressurized system.
A 20-year warranty, and the construction behind it. Most solar water heaters guarantee the tank for 5 to 10 years; a few reach 15. Twenty years is a claim only genuinely durable construction supports. Here the inner tank is CRCA steel cold rolled close annealed, the grade used where a smooth, uniform surface is needed finished with a porcelain enamel coating. Porcelain enamel is glass fused to steel at high temperature rather than a coating applied on top, which is why it bonds permanently and resists the scaling that destroys ordinary tanks. The outer shell is powder-coated steel or stainless.
Built for hard water. On borewell supply, where mineral-heavy water destroys an ordinary tank in three to four years, the porcelain enamel surface and 2000 ppm rating are what let this unit carry a 20-year guarantee. 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.
Sized for a large family. At 270 litres this serves 6 to 7 people sharing hot water across a morning a joint family, or a household with several bathrooms in use at once. Twenty-six evacuated tubes feed the tank, each holding 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.
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. If your overhead tank sits lower than 6 feet, ask our team about Supreme's Sleeper models, which need only 1 foot of height.
On sizing, 270 litres serves 6 to 7 people. More than that, step up to a larger capacity; four or five, the 220 LPD 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 270 LPD suits your household, 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.
