The connecting pipe (flue pipe) between appliance and chimney must match both in diameter. DruckZugPro checks whether your combination is compliant and calculates the pressure loss through the connecting pipe.
Highlights
- Automatic check: collar diameter vs. chimney cross-section.
- Pressure loss in the connecting pipe is included in the calculation.
- Bends and pipe length are accounted for.
How it works
- Enter the collar diameter of the appliance (or select from database).
- Define flue pipe geometry: length, bends, diameter.
- DruckZugPro calculates the impact on the overall system.
FAQ
Can the flue pipe be smaller than the collar?
In principle no: a cross-section reduction in the connecting pipe is not permissible. Equal diameter or an expansion towards the chimney is standard.
How many bends are allowed?
The standard permits bends, but each increases flow resistance. DruckZugPro accounts for up to 3 bends in the calculation and shows the resulting pressure loss.
