Water treatment guide: HPM reports an ICOM update for commercial hot water work

There is a new version of the water treatment guide you lean on when you spec and price commercial hot water work. According to Heating and Plumbing Monthly (HPM), the Industrial and Commercial Heating Equipment Association (ICOM) has updated its guide, “Water Quality Considerations of Domestic Hot Water Systems for Commercial Applications”, and aimed it at contractors, facilities managers and specifiers. What nobody has said yet is what actually changed.

For your tools and technology choices, the reported scope makes the guide relevant when you specify treatment and when you price the maintenance that follows. HPM says the same document sits across those stages, which helps where one person in your business writes the spec and another handles the follow-up work.

HPM says manufacturers and water treatment specialists helped develop the guide, and that it covers scale, corrosion and biofouling with water quality as the focus. Its account runs from initial water analysis and treatment selection through commissioning into monitoring and ongoing maintenance, so the reference reaches your team when a commercial hot water installation is being handed over.

The water treatment guide covers commercial hot water work

The wording of the title matters. “Domestic Hot Water” sits next to “for Commercial Applications”, and commercial hot water systems are the scope HPM describes. The report gives you no basis for stretching the update across every household plumbing job or every heating circuit.

HPM describes the guide as accessible to technical specialists and to people with limited knowledge of water treatment chemistry. That pitch suits a team building its own competence, and it reads like the kind of on-the-job upskilling that sits behind wider digital skills for construction. HPM adds that the guide stresses using competent water treatment professionals and following relevant regulations and guidance, and its account names Legionella control and water safety.

No new deadline lands on your business

This is a reported guidance update, not a rule change. HPM sets no legal obligation, prohibition or deadline against it, so nothing here moves the duties you already work to. Better water quality does mean less scale and corrosion, longer system life and less waste, which is the efficiency case that sustainable construction training makes for green building.

HPM says you can download the updated guide free from ICOM’s website, though it gives no edition number or update date. Until someone lists the changes, the only way to see what moved is to open the new copy next to your old one, and mark the parts of your spec that need another look.
