The Flat Plate Solar Water Heater combines a high-performance solar collector with a pressurized or low-pressure tank, delivering reliable hot water in all climates. Its enamel-coated or stainless-steel inner tank ensures durability, while the flat plate collector provides high output even in low light. Versatile and easy to install, it features modular collectors, a durable glass cover for impact resistance, and supports anti-freeze use in cold climates. Made from eco-friendly, recyclable materials, it is ideal for residential, villa, hotel, and small commercial applications.
