Is a Heat Network the Answer to your Carbon Reduction Challenge?

The Government has identified heat networks – 4_networks-1-opt - Peter Hawtin - peterhotherwise known district heating systems (DHS) - as a key technology to decarbonise heat and has allocated £320m of funding to 2021 to grow the heat networks market. This funding is expected to draw in up to £2 billion of additional capital investment and lead to the construction of hundreds of heat networks in England and Wales. Scotland has set an ambitious target to connect 40,000 homes to heat networks by 2020, representing 1.5TWh of Scotland’s heat demand.

A heat network may give the following benefits:

  • Local Infrastructure: heat networks enable the use of local renewable energy resources (such as heat pumps, biomass and geothermal energy) or the recovery of waste heat from industries and power stations.
  • Low carbon: 4_networks-4-opt - Peter Hawtin - peterhlow carbon and renewable energy sources for heat networks can significantly lower carbon emissions from heat (between 50 to 100g CO2 /kWh for a biomass network), compared to traditional solutions (above 200gCO2 /kWh).
  • Planning asset: heat networks can be fitted to new or existing buildings as part of local sustainability strategies. The greatest carbon savings can be achieved in the retrofit sector.
  • Consumer value: well designed and operated networks can offer competitive and stable heat prices over the long term, as well as low carbon heat.

(DHS) District Heating  Systems represent a 4_networks-2-opt - Peter Hawtin - peterhmassive infrastructure investment and huge annual running costs yet they are frequently:

  • badly designed
  • wasting a high percentage of the energy that they consume
  • assumed to efficient when they are not remotely so
  • treated as a “black box” that nobody on site understands
  • modified over decades by people who don’t understand what they are doing
  • assumed to be a “good thing” regardless of whether they are the best solution

We regularly have to unpick shocking bad design by big name M&E consultancies or suppliers cutting corners to reduce costs.

The Green Consultancy offers the highest level of expertise to optimise existing systems or design new ones or extensions:

  • thorough survey and forensic study
  • comprehensive analysis of all relevant data using superior EU standards
  • thermal/hydraulic modelling using software developed and tested on numerous DHS over many years

We have carried out DHS optimisation and re-design work for University of Bristol and Lancaster University

If you are considering a new DHS or an extension, or want to improve the efficiency of your existing system, please call John Treble, to discuss your requirements, on 01761 419081, or email John@GreenConsultancy.com

District Heating Optimisation and Redesign for University of Bristol

“The Green Consultancy redesigned the District Heating System at our Langford site to dramatically improve its energy efficiency. Their consultant gave a clear and concise explanation of the new design and answered all questions from the team charged with progressively implementing and commissioning the new design in a way that fully inspires our confidence in the results. At last we have someone who understands CHP and thermal stores, rather than having just read about them in a book and made up a design as they go along!”

Dave Baker, Mechanical Building Services Engineer

District Heating System Feasibility Studies for Lancaster University

"I have been consistently impressed by the level of skill, understanding and capabilities of The Green Consultancy. They have delivered a very insightful BMS health check, and subsequently a very thorough and robust set of proposals for our district heating system which helps make the system fit for the next 50 years. I look forward to continuing to work with The Green Consultancy, as we move to a low carbon future."

District Heating Negotiation for Department for Education

Department for Education engaged The Green Consultancy to review the proposed technical and contractual terms for the supply of heat to Cornerstone Digital Academies from a district heating scheme operated by E.ON Energy Solutions Ltd – and then to negotiate with E.ON.
