Hard Water Protection for Tankless Units in Little Rock, AR
Calcium scale is the leading cause of tankless heater failure. Many municipal systems in Arkansas draw from lakes and reservoirs that supply fairly soft water, though some areas see more mineral-heavy water from groundwater sources. Scale coats the heat exchanger, reducing efficiency and triggering error codes. We install isolation valves so the unit can be flushed with a vinegar or descaling solution once a year. A scale inhibitor cartridge or whole-home softener provides extra protection.
