Hydronic Heating System


Hydronic Commercial System Protector

Corrosion and scale can block narrow boiler waterways and high performance circulators. MC1+ prevents scale buildup and dramatically slows harmful oxidation that causes the formation of black sludge.

MC1+ can be used to complement the system-saving performance of your MagnaClean® filter by dosing directly into the MagnaClean canister, or the expansion tank.

  • Protects against corrosion and scale
  • Maintains heating efficiency
  • Treats up to 700 gallons
  • Helps reduce heating and maintenance bills

Use as part of ADEY® Best Practice

For complete hydronic heating system care, MC1+ should be used as part of ADEY's five-step Best Practice process. Step 4, protect, uses MC1+ to dose the system following a MagnaCleanse® system flush for ongoing protection against corrosion and scale.

How to use – professional use only

One bottle of MC1+ treats up to 700 gallons. Introduce MC1+ to the system via a MagnaClean filter. For open vented systems MC1+ can be added via the expansion tank, remembering to remove sufficient water via the drain-point to ensure MC1+ enters the system circuit. MC1+ levels should be checked regularly during annual system service, or following any system maintenance requiring full or partial drain-down.


ADEY is a carbon neutral company and cares about the environment. MC1+ is classified as non-hazardous, non-toxic and biodegradable.
