The iSpring ED2000HD Whole House Electronic Water Descaler is an innovative, computerized water conditioning system that solves hard water problems without using chemicals, salt, or filter cartridges. By leaving the minerals in the water and preventing them from forming limescale deposits, it effectively conditions the water. The system works by wrapping two antenna cables around the main water pipe to create a coil. This coil generates a complex, frequency-modulated electromagnetic waveform, inducing an oscillating electric field in the water. This process agitates water molecules, releasing carbon dioxide and causing the premature precipitation of calcium bicarbonate. As a result, the water's solubility increases slightly, allowing it to dissolve existing scale deposits over time. Limescale on fixtures will soften with regular exposure to treated water from the ED2000HD.
