The Supreme Heavy Plus 300 LPD FPC Solar Water Heater is a flat plate collector system with a glass-lined-coated tank, rated to handle water hardness up to 4000 ppm the highest hard-water tolerance in our range.
4000 ppm is what makes this different. Most solar water heaters top out at 600 ppm for flat plate systems, or 2000 ppm for the best glass-lined tanks. This Supreme handles double that. If your borewell water is genuinely severe the kind that scales a geyser within a year and has defeated equipment before this is built for it. Across the hard-water belts of Bangalore, Hyderabad, and much of peninsular India, that tolerance is the difference between a heater that survives and one you replace.
Flat plate technology. The collector absorbs sunlight across its full surface and heats water directly into the tank the proven, low-maintenance technology, reliable in strong direct sun. On cold early mornings and heavy overcast it warms more slowly than an evacuated tube system, which is a genuine trade-off worth knowing before choosing between them.
An honest point on the guarantee. As specified, the tank carries 2 years with 5 years on the collectors considerably shorter than Supreme's ETC range at 20 years. This unit's strength is its hard-water tolerance rather than its warranty length. If your water is severe enough to need 4000 ppm capability, ask our team about Supreme's ETC models, which combine high hardness ratings with 20-year cover usually the better buy for a hard-water home.
The price includes transportation to your house, lifting to the terrace, and installation. You arrange the plumbing and electrical wiring.
