Why Sediment And Hard Water Can Still Affect Tankless Water Heaters

tankless water heater at home

Tankless water heaters are low-maintenance and long-lasting heating solutions. Despite being low maintenance, they’re not immune to the common water heater issues. Sediment and mineral deposits accumulate over time. They are not noticeable, but cause stubborn clogs that lead to damage and water heater repair in Shoreline, WA

Tankless Water Heaters, Sediment, And Mineral Deposits

One common misconception in tankless units is that since they don’t store water, they are safe from sediment buildup and mineral deposits. Homes with hard or unfiltered water are especially at risk of developing issues over time.

Even without a storage tank, mineral-heavy water flowing through the system still leaves behind calcium and magnesium buildup on heating elements and internal pipes. The accumulation reduces efficiency and increases heating time. This strains the heater, consumes more energy, and causes failure. 

Damage From Sediment And Mineral Accumulation

Minor mineral buildup soon leads to a costly repair if ignored. Hot water heater repair becomes necessary when the water temperature becomes inconsistent or for sudden pressure drops.

Sediment can accumulate inside the unit’s flow sensor or heat exchanger. These parts are critical for proper water heating. When blocked, they can overheat or malfunction. When strange noises or system shutdowns happen, homeowners must call for tankless water heater repair

Proper water filtration is a major source of these issues. In severe cases, the installation of a whole-house water filter system can resolve the issue and improve the home’s water quality.

Yearly Maintenance Is Key

Failing to address mineral buildup increases the water heater repair cost. Many hard water issues are preventable. But the longer sediment and minerals collect inside the unit, the more extensive the damage becomes. Repair bills can become as expensive as replacement costs.

Routine water heater maintenance remains the best defense against sediment-related problems. Annual flushing of the system, deep cleaning keep them clean. But installing a whole-home water softener removes the source of sediment and minerals.
