Detecting water leaks and identifying appropriate intervention.
In closed heating and chilled water systems, even small faults can escalate quickly if they go undetected. One of the most disruptive issues we see in practice is a sudden or intermittent water leak. If not identified early, it not only leads to collateral flooding damage but also allows fresh aerated water to enter the system, raising dissolved oxygen and diluting inhibitors.
This is exactly what happened in a hospital’s LTHW system monitored by Hevasure. Over the course of a few weeks, we detected several intermittent leaks by measuring flow rates on the water make-up line and corresponding changes in dissolved oxygen and conductivity levels.
What made this case particularly significant was that the leak was not readily visible, as it was hidden behind plantroom walls. Routine water sampling would not have picked this up, but by measuring multiple parameters in real-time, the Hevasure system flagged up the problem straight away. The Hevasure system data told a clear and consistent story. While the inline water meter readings confirmed the unexpected demand for fresh make-up water, high dissolved oxygen levels and reduced conductivity readings pointed to potential corrosion issues if not remedied. Taken individually, these readings would only give a partial picture. But together, they provided a clear diagnostic picture that allowed the root cause to be identified and appropriate interventions to be made.
Without this level of continuous monitoring, the leak would likely have remained undetected for an extended period, gradually degrading water quality and accelerating corrosion across the system. But with Hevasure’s real-time monitoring in place, the event was identified early, enabling engineers to locate the source of the leak and take corrective action before any major system failure occurred.
This is not a theoretical benefit – it is a practical example of how continuous data visibility changes outcomes on live systems. With over 12 years of experience and approaching 200 installations across the UK, our Aquila system has repeatedly demonstrated its ability to detect exactly these types of intermittent, high-risk events.
Now in its fourth generation, the system is designed not just to show that something is wrong, but to provide the clarity needed to understand what is happening and why – in real time.
By identifying issues early and enabling targeted intervention, downtime is reduced, system damage is prevented, and asset lifespan is significantly extended.
