Water from your overhead tank flows into the solar heater’s storage tank. As sunlight strikes the vacuum tubes, heat is absorbed and transferred to the water. Once heated, the water flows downward through gravity to your bathrooms, kitchen, or wherever needed. The system is low-maintenance, dependable, and built to last.
