Products Description
Passive Solar Water Heaters are simple, low-maintenance systems that rely on natural convection or gravity to circulate water, without the need for pumps or controllers. They use solar collectors to absorb sunlight and directly heat water, which then flows into a storage tank. Common types include integral collector-storage (ICS) systems, where water is heated and stored in the same unit, and thermosyphon systems, where heated water naturally rises into an elevated storage tank. While typically less efficient than active systems, passive solar water heaters are more affordable, durable, and reliable due to their minimal moving parts—making them ideal for households in sunny regions with moderate hot-water needs.
