BESA & BeyondField
Evidence from 10,000
HIUs

CIBSE Accredited CPDs

This CPD presents field evidence gathered from over 10,000 Heat Interface Units (HIUs) deployed across UK heat networks, comparing real-world performance against laboratory test conditions defined under the BESA HIU Test Regime. This CPD is relevant to engineers, specifiers, consultants and asset manager working with heat networks and HIUs.

CPD Agenda 

BESA Testing

Understanding BESA HIU performance graphs across all operating modes

Real-World Performance

Why real-world HIU performance differs from BESA test results
How to specify and manage HIUs to reduce the performance gap in practice
Insights from 10,000+ HIUs operating on UK heat networks

Asset Management

Using field evidence to inform better HIU specific and asset management decisions

Flexible delivery, practical insight and expert-led discussion

Frequently asked questions

Continuous Professional Development

What is the main objective of the "BESA & Beyond – Field Evidence from 10,000 HIUs" CPD?+

This seminar analyzes real-world operational data gathered from over 10,000 Heat Interface Units (HIUs) deployed across UK heat networks. It compares actual in-field performance against laboratory test results defined under the standard BESA (Building Engineering Services Association) UK HIU Test Regime.

Why compare laboratory BESA test performance with real-world field data?+

While BESA testing provides a vital benchmark for HIU efficiency under controlled laboratory conditions, real-world deployment presents fluctuating loads, varying primary flow temperatures, user behavior variations, and water quality challenges. This CPD bridges the gap between theoretical test scores (such as VWART - Volume Weighted Average Return Temperature) and long-term network efficiency on live sites.

What key insights and technical topics are covered in the seminar?+
  • Field vs. Lab Performance: Discrepancies between expected laboratory benchmarks and actual field operating metrics.

  • Low Return Temperatures: Strategies for consistently maintaining low return temperatures across space heating and Domestic Hot Water (DHW) production.

  • Keep-Warm Mode Optimisation: Managing standby heat losses and bypass settings to avoid grid degradation during low-load periods.

  • Data-Driven Optimization: Leveraging remote monitoring and energy metering data to identify anomalous performance and refine heat network operation.

Who should attend this CPD course?+

This seminar is designed for mechanical consulting engineers, M&E contractors, heat network designers, social housing providers, local authority energy officers, and asset managers looking to optimize heat network reliability and lower operating costs.

 

What is the delivery format, duration, and accreditation status?+
  • Accreditation: CIBSE Accredited CPD presentation.

  • Duration: 1 hour to 1.5 hours (typically delivered as a lunchtime session).

  • Format: Interactive seminar hosted in person at your office or delivered online, featuring open Q&A and practical case studies.

  • Booking: You can request a session directly on the SAV Systems BESA & Beyond CPD page.
