The Seven SS Stars Non-Pressurized Solar Water Heater 250 Liters (Stainless Steel) is a reliable and cost-effective solar water heating system designed for long-lasting performance. Built to handle both fresh and borehole water, it features a corrosion-resistant stainless steel inner tank, making it highly durable. This non-pressurized system allows water to enter under pressure but releases it through natural convectional flow. For improved water pressure at the outlet, a compatible hot-water pump can be installed.
