Heat Network DHW Diversity

Diversified DHW and space-heating peak kW per riser/branch from an array of dwelling groups (instantaneous or storage HIU), via the DS 439 coincidence-factor curve and CP1's 0.62+0.38/N space-heating rule.

Dwelling groups

No groups added yet — add each riser/branch as a group of dwellings sharing one HIU type

Add at least one dwelling group (dwellings + HIU type and per-dwelling loads) to size the diversified demand
