Maintain the design specification and energy efficiency|Restore energy efficiency|Inhibit the formation of scale and sludge|Minimize corrosion of system metals|Express format for easy use|Good practice dictates that hydronic central heating systems should be thoroughly cleaned and flushed before installing a new boiler, after which a chemical inhibitor should be added to ensure the system is protected from corrosion, scale and sludge build-up|These procedures should also be employed when major work is carried out on a system|A clean, protected system helps ensure that the heat generated by the boiler is transmitted efficiently into the house over the long term
