Tankless water heaters are celebrated for their efficiency and longevity, but they require consistent maintenance to perform optimally. Regular flushes are a critical part of this upkeep, preventing scale buildup and maintaining the system’s efficiency. Without routine flushing, your tankless water heater may experience reduced performance and a shortened lifespan. By understanding the significance of this maintenance step, homeowners can avoid costly repairs and ensure a steady supply of hot water.

How Scale Buildup Affects Tankless Water Heaters

Mineral-rich water, or "hard water," is a common culprit behind scale buildup in tankless water heaters. Over time, minerals like calcium and magnesium accumulate in the unit’s heat exchanger, reducing efficiency and potentially causing overheating. This buildup forces the system to work harder, increasing energy costs and wear on components.

Regular flushing removes these deposits, restoring the heat exchanger’s efficiency and ensuring your heater operates at its best. Our team at Advanced Heat, AC & Plumbing specializes in preventative maintenance to keep your water heater functioning efficiently. Learn more about us here.
