BACKGROUND

Heat networks have huge potential to help address fuel poverty and contribute towards the UK’s Climate Change targets. As such, they have received considerable Government support in recent years, mainly aimed at encouraging the installation of new networks through the Heat Networks Delivery Unit (HNDU). However, many existing installations remain dormant or are performing suboptimally, with experiences of antiquated or poorly-designed systems undermining networks’ reputation for reliable, low carbon, cost-effective and comfortable heat.

The Energy and Climate Change Committee (2016) has also stated that the UK is not yet halfway towards its 2020 targets of achieving 12% heat from renewable energy, and this is unlikely to be achieved through the installation of new system alone. Greater focus on existing heat networks is required in order enable operation and increase optimisation.

REPORT: How to optimise an existing system for improving performance

The CBx Research on Low Carbon Heat Networks investigates the barriers around existing heat network operation. Over the course of a year, CBx and the steering committee have provide case studies and held discussion with expert designers, developers, engineers, government, housing associations, and legal advisers, to provide an evidence base of current existing networks. Coupled with knowledge from existing industry research and standards, CBx has developed an evidence led guide to enable operation and optimisation of heat networks to achieve better performance.

Hear from our Steering Committee:

“This research is vital for those who are struggling with existing decentralised energy systems. Those who commission, install, manage and maintain these systems need to start getting it right otherwise low carbon technology like combined heat and power will become unpopular and unused. The more information that is out there the better and this research provides some critical insight into not making the same mistakes again. This research will also be very timely and insightful for our SHIFT accredited landlords and our wider network”
Bevan Jones, Managing Director, Sustainable Homes

 

“We strongly believe low carbon heat networks have a vital role to play in helping to address fuel poverty and contribute to the UK’s climate change targets. At Hilson Moran we’re dedicated to keeping the practice at the forefront of sustainability legislation and assessment techniques, and as such are thrilled to partner with CBx on this research project”
Dan Jestico, Head of Research & Development, Hilson Moran

 

“District Heating Networks have the potential to deliver long term, low carbon and cost effective heat to a wide range of end users throughout the UK, but the performance of existing systems is often found to fall short of expectations. Willmott Dixon Energy Services are continually developing the detailed design, installation, and operational processes required to deliver high performance heat networks and ensure energy and cost savings, and comfort and satisfaction for users and operators. The work conducted by CBx aligns well with our experience and highlights some key action areas for the industry to close the performance gap on new and existing systems. This is critical to ensure the long term viability and success of heat networks, now and in the future.”
Dr Zachary Gill, Senior Energy Solutions Engineer, Willmott Dixon Energy Services

 

“Catalyst is committed to providing low carbon and affordable heat to our residents and we understand the importance of integrating district and communal heating schemes into our new schemes to achieve this.  CBxchange have produced this valuable and timely piece of research that will help Catalyst - and no doubt many other social landlords, local authorities and private developers - to better understand the complexities and issues facing the design, installation and maintenance of district and communal heating.  Consequently, this report provides a valuable tool in supporting our quest to reduce carbon emissions and provide warm, affordable homes.”
Julia Moulder, Executive Director of Property, Catalyst Housing Limited
