Sufficient chimney draught is the basic prerequisite for safe operation. If draught is too weak, smoke enters the room. If too strong, fuel burns too fast. DruckZugPro calculates the available and required draught per DIN EN 13384-1.
Highlights
- Calculation of available and required draught.
- Effect of chimney height, diameter, and material on draught visible at a glance.
- Instant result with clear statement: draught sufficient / draught insufficient.
How it works
- Enter appliance data (output, exhaust temperature, mass flow).
- Define chimney geometry (height, cross-section, material, termination).
- DruckZugPro shows whether the natural draught is sufficient for the appliance.
FAQ
What influences chimney draught most?
The effective chimney height and the temperature difference between exhaust gas and outside air. Taller chimneys and hotter exhaust produce more draught.
What if the draught is insufficient?
Options: extend the chimney, adjust the cross-section, or choose an appliance with lower pressure demand. In the configurator you can try different variants.
