300L High-Capacity Storage: Proudly made in India, this 300-liter system is designed to provide a massive hot water supply for large families of 6–10 people or small commercial hospitality units.
Hard Water Specialist: Specifically engineered for areas with borehole or “hard” water, featuring advanced tank protection that resists scaling and mineral buildup better than standard solar heaters.
High-Efficiency ETC Technology: Utilizes 30 Triple-Layer Evacuated Tube Collectors (ETC) that maximize solar absorption (up to 95%) and function effectively even on cloudy or cold days.
Superior 72-Hour Heat Retention: Insulated with 50mm–65mm high-density compressed PUF (Polyurethane Foam) to ensure water stays hot for up to three days, even during overnight temperature drops.
Food-Grade Stainless Steel Inner Tank: Constructed from premium SUS 304-L grade stainless steel with argon-arc welding to ensure long-term hygiene and 100% leak-proof performance.
Sacrificial Magnesium Anode: Includes a built-in magnesium rod that protects the inner tank from galvanic corrosion, significantly extending the lifespan of the system in harsh water conditions.
Gravity-Fed (Non-Pressurized) Reliability: A simple, high-performance “Thermosiphon” system that works seamlessly with rooftop water tanks, requiring zero pumps and minimal maintenance.
Weatherproof Powder-Coated Outer Body: Features a durable, rust-proof outer casing designed to withstand intense UV radiation, high humidity, and coastal salinity without corroding.
Optional 2kW Electric Backup: Equipped with a dedicated port for an integrated electric heating element, providing a reliable hot water safety net during the heavy rainy seasons.
Rapid ROI (Return on Investment): Designed to reduce monthly water heating bills by up to 80%, allowing the system to pay for itself within 24–36 months of installation.
Includes all accessories- Assistant tank, Controller, Element, Magnesium Rod
Experience the power of world-class engineering with the Supreme 300L Non-Pressurized Solar Water Heater. Proudly made in India by one of the world’s leading solar thermal manufacturers, this system is specifically designed to meet the rigorous energy demands of modern households and commercial businesses. Delivering a massive 300-liter capacity, the Supreme series is celebrated for its ability to handle hard water (borehole water) without the scaling and corrosion issues that plague standard solar heaters.
Operating on the natural Thermosiphon principle, this non-pressurized (gravity-fed) system is the most cost-effective way to secure 24/7 hot water. Whether you are in a highland region with cold mornings or a coastal area with salty air, the Supreme 300L is built to perform, offering a lifespan of over 15–20 years while reducing your electricity bills by up to 80%.
The primary challenge for solar heaters in many regions is mineral buildup. The Supreme 300L addresses this with industry-leading technology:
Advanced Glass-Lining (GL): The inner tank features a specialized glass-lined/ceramic coating that protects the metal from chemical attack and scaling, even with water hardness up to 1300–4000 TDS.
High-Grade Stainless Steel: Constructed with food-grade SS-304 L grade steel, ensuring your water remains hygienic and the tank remains rust-free.
Corrosion Resistance: The outer body is powder-coated for extra protection against humidity and extreme weather conditions.

Supreme uses advanced three-target vacuum tubes (SS/CU/AL coating) that capture over 95% of available solar radiation. These tubes act like a thermos; once heat is absorbed, it cannot escape back through the vacuum, ensuring high-temperature water even on cloudy or rainy days.
The tank is insulated with 2.5-inch (approx. 65mm) high-density compressed PUF (Polyurethane Foam). This “heat-lock” technology is so effective that it can store hot water for up to 48–72 hours, allowing you to use today’s heated water even on a rainy tomorrow with minimal temperature loss.
Utilizing precision CO2/Plasma welding and non-welding technology on key joints, Supreme tanks are built to prevent leaks. The seamless design ensures structural integrity and reduces the points where rust typically begins in cheaper alternatives.
Each 300L unit comes equipped with a long-lasting Magnesium Anode. This sacrificial rod attracts corrosive elements in the water, sacrificing itself to ensure the inner tank walls remain pristine and scale-free, drastically extending the system’s life.
With the rising cost of electricity, the Supreme 300L is an investment that pays for itself. Depending on your usage, the system typically achieves full ROI (Return on Investment) within 2 to 3 years, after which your hot water is essentially free for the next decade.
