Energy savings of up to 50% for maintaining the temperature of domestic hot water in distribution pipework are expected to be achieved using a single-pipe system with Raychem HWAT trace heating compared with a conventional recirculation system in the redevelopment of Epping Forest College Campus..
In addition, eliminating the need for secondary pipework achieves cost savings in space, material and installation and savings in installation time.
