The newly released draft of the Heat Network Technical Assurance Scheme (HNTAS) and accompanying Technical Standard TAS1 (2025) marks a significant shift in how heat networks will be designed, commissioned, and maintained as the UK targets 20% of national heat demand being met through heat networks by 2050.
A major pillar of TAS1 is the requirement for continuous, realtime monitoring of water quality in both chemically treated and chemically depleted closed systems. To protect asset integrity, prevent unplanned outages, and maximise thermal efficiency, operators will now be expected to track key system health indicators, including:
- Top-up volume
- Corrosion rate
- Conductivity
- pH
- Dissolved Oxygen (DO)
Hevasure has been at the forefront of real-time closed system water monitoring for more than a decade. Our advanced sensor and data acquisition technology, combined with sophisticated analytics, are already aligned with the requirements of
TAS1, providing heat network designers, installers, and maintenance teams with a robust solution for achieving full compliance.
With 12 years of field-proven expertise, Hevasure offers the insight and tools needed to protect system performance, extend asset life, and ensure adherence to the upcoming HNTAS framework.
