Specifically, CP1 (2020) recommends a maximum flow temperature of 70°C on new schemes, encouraging specifiers and contractors to consider fourth generation heat networks. These networks, which typically favour low-carbon heat sources like heat pumps and waste heat, are suited to polymer pipework. The guidance goes on to describe how these pipework solutions can also play a major role in the implementation of district heating schemes across the UK.
With renewable heat networks increasing in popularity as a means of decarbonising buildings in line with Government net zero emissions targets, CP1 (2020)’s messaging comes at a crucial time, says Steve Richmond, Head of Marketing and Technical at REHAU Building Solutions, a leading district heating pipework supplier.
