The Supreme Sleeper Heavy Plus 270 LPD Solar Water Heater is an evacuated tube system with an enamel-steel glass-lined tank at 2.5mm, sized for 5 to 7 people, rated to handle water hardness up to 4000 ppm and carrying a 20-year tank warranty. It uses 26 tubes and needs the overhead tank just 1 foot above terrace level.
This is the most capable water heater we stock for difficult conditions. Two problems disqualify most solar water heaters in Indian homes: water too hard for the tank, and an overhead tank set too low for gravity feed. This unit solves both. At 4000 ppm it handles the most severe borewell water double what the best glass-lined tanks manage, and far beyond the 600 to 1000 ppm typical of the market. And as a Sleeper model it needs only 1 foot of height above the terrace, where a conventional gravity system needs 6. If your water is hard and your Sintex sits low, this is likely the only configuration that will work properly.
4000 ppm, backed by a 20-year warranty. That combination is what makes the rating credible. A hardness claim without a long warranty behind it is just a number; twenty years of cover on a tank rated for the hardest water means the manufacturer is standing behind it. The construction is enamel steel with a glass-lined coating at 2.5mm thicker than the 1.6mm typical of the market. On water that destroys ordinary tanks in three to four years, that is the difference between a heater that lasts two decades and one you replace twice.
The Sleeper design, explained. 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 many Indian rooftops that is not the case the Sintex sits low, or the layout does not allow a raised platform and buyers are simply told solar will not work for them. The Sleeper needs 1 foot. If you have been told your rooftop cannot take a gravity-fed system, this is the model to ask about, and it does not compromise on the tank to achieve it.
Sized for a large family. At 270 litres this serves 5 to 7 people sharing hot water across a morning. 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.
A compact footprint. This unit needs only 8 feet by 4 feet of clear terrace space half the area the standard 270 LPD requires, which matters on a crowded rooftop.
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.
The price includes transportation to your house, lifting to the terrace, and installation. You arrange the plumbing connection.
