Central Heating Diversity: %
Peak Flow Temperature: C

Hot Water Hourly Profile (default values from EST study):

Heat input is initially set to the minimum, resulting in maximum storage sizes. Increase the heat input to reduce storage sizes.

Network DHW Priority requires networked HIUs that can respond to signals from planroom to limit central heating loads for short periods to enable load prioritisation, and thereby limit the instantaneous demand on the system as required. This allows peak heat input to be safely sized to average hourly loads and may avoid the need for storage.
