Water Heater De-Scaling Program (WHDS)

water causes scale because it contains calcium carbonate (lime) and other minerals that stick to pipes and water heaters as water is heated. As scale accumulates inside water heaters, it reduces their life and energy efficiency. De-scaling natural gas water heaters and storage tanks on an annual basis prolongs the life of the equipment and saves energy.
