Heat Network Distribution Losses
Array-first heat network segment losses (bare/insulated pipe or pre-insulated bonded-pair presets): total W, annual kWh, and loss as a % of annual delivered heat with an informational CP1-style benchmark band.

Annual energy & delivered heat
h/yr
Heat networks typically run year-round (DHW + space heat); default 8,760 h
kWh/yr
From heat generation meters/estimate — the loss % KPI's denominator
Add at least one network segment (length + pipe spec or preset) to calculate losses
