i48: Community/District heat pumps

5 supporter (+ 1 potential)

Given the high density of housing in the region, and especially blocks of flats/terraced housing  community heat pumps could provide more sustainable heating at a lower cost (example project https://finn-geotherm.co.uk/case_study/landmark-renewable-heating-scheme-cuts-costs-for-flagship-res...

River-source district heating

collective rating: 
| implemented: 
Large scale district heating is seen as a way of decarbonizing heat in urban areas and is now implemented in parts of Leeds. There is also a large system in Sheffield. I can be an effective way to decarbonise provision of heat in historic buildings and those that are difficult to retrofit. The key is finding low-carbon heat sources to supply heat to the system. The common apporach is to use municipal solid waste incineration to generate electricity and heat for district heating. This can be said to be low carbon heat but this is debatable. Many district heating systems use gas boilers or combined heat and power systems. As electricity is decarbonized, this makes less sense - using electricity becomes a lower carbon solution. Delivering electrified heat to district heating makes most sense when large heat pumps are used. Such heat pumps can deliver heat at high temperatures if necessary and can also deliver cooling. All heat pumps need a low temperature heat source - air or water based. One promising approach for Yorkshire is to use the energy resources of rivers with these large scale heat pumps. A very good example of this can now be found on the Clyde: https://www.west-dunbarton.gov.uk/council/newsroom/news/2020/dec/district-heating-network/

Community heat pumps for housing blocks

There are now several examples of community heat pump schemes in Leeds. This have been deployed a a number of sites where LCC has pairs of tower blocks that previously used electric storage heaters. In these schemes, a small heat pump is installed in each flat along with new radiators and water storage system. All the heat pumps are connected to a shared geothermal heat exchanger. This consists of about a dozen boreholes drilled in the ground surrounding the blocks of flats. These have reduced tennants bills significantly along with the related emissions. This approach could be thought of as a type of local district heat network. Something similarl could be done in terraced streets with boreholes undner the road.
