![]() ![]() These systems deliver additional benefits and savings as they are able to share heat/coolth across the network and capture waste heat from secondary heat sources like the heat from London Underground ventilation shafts and local data centres. In the UK there is a drive towards 5th generation heat networks involving ambient temperature loops (13 - 25✬). ![]() Most of the Scandinavian systems use high temperature 3rd or 4th generation heat networks (>50-80✬) and these are often driven by fossil fuel powered Combined Heat and Power (CHP), which are carbon intensive and also impact on local pollution/ particulates. Currently, around 2% of all heat in the UK is provided by heat networks compared to other countries such as Sweden/ Denmark, where they have more than 30% delivered in this way. Heat networks are a key technology proposed in the UK Government's Clean Growth Strategy for delivering low carbon and low-cost energy to urban communities in the UK.
