Chris Caton, Product Manager at Ideal Commercial Boilers, discusses the importance of water treatment, highlighng the key takeaways for commercial applicaons from the Industrial and Commercial Energy Associaon’s water treatment and condioning guide.

‘Dirty water’ is an inevitable consequence of an aging system, but if transferred into the new boiler it will affect its ability to run efficiently and can lead to boiler breakdowns and even failure.


We encourage building managers to consider water treatment, which ensures the longevity of the boiler by protecting its internal parts from corrosion and the build-up of scale. Historically, commercial heating systems have not had the same level of industry guidance regarding water treatment as domestic installations. The Water Treatment and Conditioning of Commercial Heating Systems guide published by ICOM changes this situation. It sets out best practice and tackles the issue of poor water treatment in commercial heating systems, from design considerations for new systems to analysing water in existing systems. The guide spells out the consequences of failing to adequately treat water, with advice on how to make heating systems more efficient and avoid failure. The guide included input from industry professionals, including Ideal

Commercial. We believe it’s one of the most crucial pieces of literature to be released to the industry in recent years because poor water treatment and conditioning in commercial heating systems, in turn causes problems with the appliance and ancillary components. It’s easy to blame the boiler for failure but we believe there is still more work to be done further down the chain in order to educate around the importance of doing things correctly. Boilers should not be fired before the system water has been treated and, if applicable, system protection equipment installed. In some cases, a lack of water treatment could invalidate the manufacturer’s warranty.


Five facts on the ICOM water treatment guide


uWater treatment for domestic heating systems has been very well defined and, in most cases, implemented effectively. But this has not been the case for commercial systems, causing a range of issues related to fouling, biofouling, corrosion and limescale. uThis guide provides everyone involved in water treatment, from specifiers to maintenance contractors, a definitive guide as to how they should identify the best water treatment regime for a particular system and implement it effectively.


uThe guide notes that system designers have an opportunity to assess suitable water treatment methods from the outset, based on the specified mechanical equipment and pipework for the project. uThe guide stresses the importance of establishing the water volume of the system so the correct proportions of treatment can be formulated. uThe guide also details each step required for effective water treatment, from initial cleaning (including cleaning methodologies) and flushing to suitable ongoing treatment.


Water treatment in heating systems is essential for their efficient operation. There has been a real
