A comprehensive heating system design for a multi-story residential apartment block. The plan details a centralized heating system with dual wall-mounted condensing boilers (115 kW each) providing 460,000 Watts total capacity. The system features a closed expansion tank (750L), circulation pumps (8 m³/h, 3-4 mss), and a cascade temperature control panel with outdoor temperature compensation.
Distribution System:
– Floor-by-floor collector-based distribution with dedicated kalorimeters for individual apartment metering
– DN80 main distribution lines transitioning to 1″ and 1¼” branch lines
– DN32 differential pressure valves at collector points
– Heat outputs ranging from 7,000 W/h (ground floor) to 12,510 W/h (typical apartment)
System Components: Include air separators, dirt/particle separators, and 5L air tubes at strategic locations. The schematic includes a complete flow diagram showing the primary and secondary heating circuits, with total system capacity of 222,650 W/h. Auxiliary systems include a domestic water hydrofor (3 m³/hour, 7.0-9.0 bar) for water pressure boosting.
