At the Date with Data event on Thursday 21st April, Guru Systems presented the most in-depth look at UK heat networks yet completed. They demonstrated how real-time data captured using Guru Pinpoint can be used to improve the performance of existing heat networks and to design new networks that achieve greater efficiencies.

pinpointDeveloped with support from the UK Department of Energy and Climate Change (DECC), Guru Pinpoint is a web-based platform that makes it easy to visualise heat network performance data, remotely diagnose the causes of inefficiency and view suggested improvement measures.

At the event Guru Systems, along with heat network consultancy FairHeat, revealed details of the data from their 16 month trial.

Casey Cole, Managing Director of Guru Systems said: “Our project showed many new heat networks suffer from high losses. There are lots of reasons why, but one feature they all share is a lack of performance data.”

“We developed Guru Pinpoint to fill this gap. Pinpoint accepts data from metering systems and BMSs, analyses it and provides metrics on which the cost benefits of different interventions can be tested.”

Gareth Jones, Managing Director of FairHeat picked up this theme: “Using the data from Pinpoint we have been able to prove that it’s cost effective to significantly improve the performance of heat networks.

“In these trials we have reduced network heat losses by 60-70%. We have also shown than even minor tweaks – like turning down the hot water thermostat in dwellings – combine to produce dramatic impacts on the overall network performance.”

All the presentations from Date with Data are now available to download and you can visit to register for free access to real-time data from UK district heating schemes.

Date with Data was chaired by Jenni McDonnell from the Knowledge Transfer Network. Also presenting on the day were David Wagstaff, Head of Heat Networks at DECC, Leigh Dodds of the Open Data Institute, Phil Jones from Chartered Institution of Building Services Engineers (CIBSE),Tim Rotheray, from Association for Decentralised Energy (ADE) and Bjorn Folkeson from the Technical Research Institute of Sweden (SP).
