Why Anti-Scale Protection Matters
Hard water minerals such as calcium and magnesium carbonate precipitate out of solution when water is heated, forming insulating scale layers on heat transfer surfaces. Even a thin layer of scale significantly reduces heat transfer efficiency and forces the burner or heating element to work harder, increasing fuel or energy consumption. The Lochinvar & A.O. Smith 100291509 standalone anti-scale product is the OEM-recommended solution to combat this issue and preserve the investment in your water heating equipment.
