Ventilation planner

Enter the internal dimensions and installation conditions. Use six air changes per hour as a planning basis to calculate airflow and explore vent positions.

Saunature’s general low-inlet / high-outlet guidance and model-specific manuals describe different conditions. Electric dimensional examples here follow HUUM CORE. Wood-stove drawings are discussion sketches. Always prioritise the actual heater manual.

About the airflow calculation and layouts

Width, depth and height give the room volume V. The planning reference Q = V × 6 uses six air changes per hour. Heater output is included in the enquiry conditions and does not change the airflow calculation.

Layout candidates refer to HUUM and Harvia guidance and heater manuals. Wood-stove combustion air is outside the calculation and needs model-specific design.

The result does not guarantee delivered airflow or legal compliance. Diagrams are schematic. Confirm wall routes, duct pressure losses and temperature and humidity limits with the installer; the actual heater manual takes priority.
