To avoid pipe oversizing, Hysopt will aggregate and weigh the different heating applications in the network. On each pipe, the supply for
domestic hot water
heating prioritised by DHW (e.g. when HIU’s are applied)
heating not prioritised by DHW (e.g. when electric heaters are applied)
are aggregated and weighted based on diversity factors.
