The potential advantages of district heating for the UK, where the technology is expected to meet 20% of the country’s heat demand by 2030. District heating (DH) is currently experiencing a renaissance the UK. Implemented across Europe during the post war period, DH remains popular on the continent in places such as Germany, Scandinavia and much of Eastern Europe. DH in Denmark, for example, currently heats over 60% of homes with that number rising to 95% in Copenhagen. In contrast, the UK, which saw significant growth in DH with the council housing boom in the 1950s – 1970s, fell out of love with DH when the North Sea natural gas network was established in the 1980s. The tide is turning, however and the UK’s energy future with regards to DH looks to be falling in line with the rest of Europe’s. The last government funded, via DECC, over 140 DH feasibility studies to the tune of over £6m. The Government’s Heat Strategy published in 2013 firmly placed DH as the preferable source of heating in urban areas by 2050. Today’s figure of 2% of domestic demand in the UK being fed by DH is predicted to rise to a figure of 20% by 2030. Why is this the case and what are the advantages of district heating?
