***** Tankless Owners****** Spring Cleaning Check!!!!!
Tankless water heaters should generally be flushed once a year to remove mineral buildup, maintain efficiency, and protect the warranty. If you have hard water, use high volumes of hot water, or notice issues like inconsistent temperatures, reduced pressure, or error codes, you should flush it every 6–9 months.
Key Indicators:
Routine Maintenance: Annual cleaning (typically 12 months) is the standard recommendation.
Hard Water: If you live in a hard water area without a water softener, flush every 6 months to prevent scale buildup.
System Errors: Error codes related to maintenance or scale buildup indicate an immediate need for descaling.
Performance Loss: Reduced water pressure, lukewarm water, or fluctuation in water temperature.
Strange Noises: Rumbling, knocking, or whistling sounds from the unit are signs of sediment accumulation
