How Do I Prevent Hard Scale Buildup Inside Boilers? | Miura

Preventing this damaging accumulation of hard water deposits is crucial to maintaining the effectiveness of a boiler. Hard scale buildup, even a seemingly insignificant one of 1/8 of an inch, can reduce efficiency by up to 20-25% due to lost heat transfer. That translates to escalating costs to operate your boiler …
