FAQ
Frequently asked questions
How often should I flush?
Once a year for tank heaters; every 3-5 years may be enough with soft water. Tankless units need descaling every 1-2 years.
Why does it matter?
Sediment builds up at the bottom, wasting energy and corroding the tank. Flushing extends heater life by years.
How long does it take?
A flush takes 1-2 hours including drain and refill time.
