Chimney height is one of the most important parameters for adequate draught. If it is too low, the draught is not sufficient for safe exhaust transport. With DruckZugPro you can check whether the effective height of your chimney is adequate for the planned appliance.
Highlights
- Effective chimney height vs. minimum height at a glance.
- Influence of roof pitch and building height considered.
- Interaction with cross-section and material visible.
How it works
- Enter appliance data (output, exhaust values).
- Enter chimney height and remaining geometry.
- DruckZugPro shows whether the height provides enough natural draught.
FAQ
Is there a minimum height?
Yes, typically at least 4 to 5 m effective height. The exact requirement depends on the appliance, cross-section, and material. DruckZugPro calculates the individual requirement.
What is the “effective height”?
The height from the flue pipe entry point to the chimney top. It is not the same as building height: when the appliance connects on the ground floor of a two-story house, the effective height can be well above the chimney height over the roof.
