How is residential heating boiler capacity determined?
Boiler capacity combines net building transmission loss, ventilation loss, domestic hot water load (approx. 20-30%), and a 5-10% distribution safety margin.
Calculate total boiler thermal capacity (kW and kcal/h) including building heat loss, domestic hot water prep, and distribution piping losses.
