The canalization fan can be added in option, even after your stove is installed.
Space-saving ducts (80 mm diameter) convey hot air up to a distance of 10 meters.
Technical details:
Insulated duct in diam. 80
Maximum length of 10 meters
Up to 4 elbows 90°
Three functioning modes:
1 - Canalization fan: OFF
Canalization fan deactivated in all powers.
2 -Canalization fan: AUTO
The canalization fan's speed follows the stove powers automatically.
3 -Canalization fan : MANUAL
The speed of the canalization fan can be set manually.
Length of ducted pipes
For efficient heat diffusion and best results, ducts should follow a direct path and be as short as possible.
For example, heat the room at the back of the stove or the room directly above it at a distance of up to 10m.
Calculation : pressure drop in canalization
The performances of a fan in a canalization are affected by the pressure drop. We can distinguish between two types of pressure drops:
primary losses (due to the pipe features)
secondary losses (due to the elbows, or valves…)
Performances results analisys
The most important losses and differences are close to the fan, in the first meters, where the air speed is high. Therfore, there is not much difference between 8 or 10 meters, and the elbows do not have a major impact on the losses.
About the temperatures, they depend pratically on the massic airflow (so, the air speed) and the pipes insulation. The results show 85°C and 56°C at 5m with 2 elbows, and around 48°C at 10m.
Conclusion
The most important losses about performances and temperatures appear in first 5 meters.
In the second part (6-10 meters), the differences are smaller.
