  • Best practice when installing a boiler onto a new or existing hydronic heating system is that the system should be thoroughly cleaned.
  • Cleaning a new system will remove any installation debris and flux residues which if left inside the system will cause corrosion.
  • Restoring an old system will remove sludge build-up, improving the efficiency of the system and help save on fuel costs.

“The absence of correct water treatment can reduce system effectiveness by typically 15%”

  • After cleaning, it is important to protect your system from returning scale, corrosion and sludge build-up.
  • Both chemical inhibitors and physical system filters are proven to provide ongoing protection for the life of the system.

  • It is important to ensure that once a system is cleaned and protected it is maintained on an annual basis.
  • Many factors can reduce the level of protection of a heating system, for instance system water losses by the removal of a radiator whilst decorating. We therefore advise checking the quality of water and level of protection annually.
