Do tankless require maintenance?
Arnett’s Plumbing highly recommends protecting your tankless water heater from San Diego County’s hard water. Periodic water heater maintenance can significantly extend your water heater’s life and minimize loss of efficiency. Read your owner’s manual for specific maintenance recommendations and detailed warranty information. Options for protecting your Noritz or Rinnai tankless water heater are scale shields, regular de-scaling (flushing) or soft water treatment.
