Closed Water System Testing & Treatment

What happens if my closed water system is not maintained properly?

If the closed water system is compromised, either through high Microbiological growth or poor water chemistry, this can cause a range of issues from blockages and poor water circulation to leaks and eventual equipment failures in pumps and valves. It can also lead to inefficient running, increased energy consumption and increased running costs, including higher maintenance costs and expensive remedial work.

How Swiftclean can help

Our closed system water analysis fully covers the standards outlined in BSRIA Closed Heating and Cooling System BG 50/2013 as highlighted in chapter 6.4: Management of the Closed Water Treatment Program.

Fully trained Swiftclean surveyors can carry out an analysis of your closed water system to determine the overall health of the system, including the amount of corrosion inhibitor present and the level of existing corrosion currently taking place.

In addition to our water chemistry analysis, we can also offer Microbiological analysis to include

  •  Aerobic Colony Count 30C (Also expressed as TVC)
  • Nitrite Reducing Bacteria (NRB)
  • Sulphite Reducing Bacteria (SRB)
  • Pseudomonas

    What happens once samples have been taken?

    Once the samples have been analysed you will receive a report which will advise you of our findings and detail any recommended remedial actions i.e. dosing of corrosion inhibitor and/or biocide or further works to reduce the level of corrosion in the system.

    How often does testing need to be carried out?

    The BSRIA Closed Heating and Cooling System BG 50/2013 guide states that new heating or cooling systems should be tested between one and three months after commissioning.

    It also suggests a more frequent schedule of water testing may be suitable during the first six months.

    Once a system is shown to be under control and well maintained, testing frequencies may be relaxed to six monthly or annually.

    Is it the Law to carry out sampling of our closed water system?

    It’s not the law to have sampling carried out. However, if it isn’t carried out on a regular basis, it can lead to corrosion of the system and leaks which could be far more costly or time consuming to fix.

    The BSRIA Guide Closed Heating and Cooling System BG 50/2013 and British Standard 8552:2012 gives best practice recommendations and guidance for the sampling and treatment of water from closed circuit heating and cooling systems in buildings

    Can I test my system myself?

    Yes, Swiftclean can supply chemicals and testing kits. Please email for further information.

    We also provide ongoing consultancy and training services in all aspects of water treatment.
