The Supreme Sleeper Heavy Plus 220 LPD Solar Water Heater is an evacuated tube system with an enamel-steel glass-lined tank at 2.5mm, sized for a family of 4 to 5, carrying a 20-year tank warranty. It uses 21 tubes to heat a 220 litre tank rated to handle water hardness up to 2000 ppm, and it needs the overhead tank just 1 foot above terrace level.
The sleeper design solves a real installation problem. Most gravity-fed solar water heaters need your overhead tank sitting at least 6 feet above the terrace to generate enough head for water to flow. On a lot of Indian rooftops that simply is not the case the Sintex sits low, or the terrace layout does not allow a raised platform, and buyers are told a solar water heater will not work for them. The sleeper model is designed for exactly that situation: it needs only 1 foot of height above the terrace. If you have been told your rooftop cannot take a gravity-fed system, this is the model to ask about and unlike some low-height designs, it does not compromise on the tank.
A 20-year warranty on a 2.5mm glass-lined tank. 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, and here it is backed by enamel steel with a glass-lined coating at 2.5mm thicker than the 1.6mm typical of the market. Combined with the 2000 ppm hard-water rating, this is a heater built to last two decades on water that destroys ordinary tanks in three or four years.
Built for hard water. On borewell supply, the glass-lined enamel construction 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.
Evacuated tube heating. The 21 evacuated tubes 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 4 to 5 bathing in the same morning window, that keeps hot water available for everyone.
Compact footprint. This unit needs 8 feet by 5 feet of clear terrace space.
If you have a booster pump on your terrace, this product is not suitable you need a pressurized model instead. Send our team a photo of your terrace and tank position and we will confirm before you spend anything.
On sizing, 220 litres serves 4 to 5 people. Six or more, step up to a larger capacity; three or four, the 165 LPD saves money.
The price includes transportation to your house, lifting to the terrace, and installation. You arrange the plumbing connection.
