Bosch Flue and Ventilation Quick Reference Guide 2022
An example of ventilation distribution for a plant room that has louvered doors and additional high level
ventilation – with reference to
IGEM-UP-10 (Edition 4) – 7.2
– Figure 2.
Example:
Based on 4 x GC 7000 WP 100kW boilers @ 96.5 kW Net heat input, placed within a boiler room that has a summer
usage below 50%
Low level ventilation: 4 x 96.5 kW = 386 kW x 4cm² = 1544cm²
High level ventilation: 4 x 96.5 kW = 386 kW x 2cm² = 772cm²
In the example above the existing louvered door, whilst providing more than the total free area ventilation requirement,
does not provide at least 20% of the required high-level ventilation within 15% of the ceiling. Therefore, an additional high-
level vent has been added.
At low level, the louvered door provides at least 20% of the low level ventilation required within 1m of the floor, so no additional
low level ventilation is required.
