The 350L Seven Stars Stainless Steel Non-Pressurized Solar Water Heater is engineered for buildings with high daily hot water consumption where reliability, durability, and energy savings are essential. Unlike painted storage tanks, this model features a fully stainless steel outer tank that offers superior resistance to corrosion, coastal weather, UV exposure, and long-term outdoor use.

Its 350-litre SUS304 food-grade stainless steel inner tank stores large volumes of clean hot water, while the 36 high-performance vacuum tubes rapidly absorb solar radiation to heat water throughout the day. Combined with high-density polyurethane foam insulation, the system retains heat for many hours, allowing users to enjoy hot water even after sunset.

Designed as a gravity-fed (non-pressurized) system, it performs exceptionally well with elevated water tanks, making it an excellent choice for homes, schools, farms, lodges, institutions, and off-grid properties where dependable hot water is required without increasing electricity bills.
