The regularity with which a tankless water heater should undergo a descaling procedure refers to the periodic removal of mineral buildup from within the unit. This maintenance activity ensures optimal performance and extends the lifespan of the appliance. For instance, a household with hard water might necessitate more frequent flushing than one supplied with softer water.
Consistent descaling mitigates the accumulation of scale, primarily composed of calcium and magnesium, which can impede heat transfer efficiency. This inefficiency leads to increased energy consumption and potentially premature component failure. Historically, preventative maintenance schedules for water heaters were often overlooked, resulting in costly repairs and replacements. Implementing a regular flushing schedule addresses these issues proactively.
