Sûti, your ducted stove
Heat up several rooms with one single stove, even on separate floors? It’s possible with Sûti’s ducted stove and canalization option.
How does a ducted stove work?
Ducted stoves are the solution to heat several rooms of your house, even from an upper floor (for well-insulated houses).
Heated air is diffused through connection pipes, enabling thus a harmonious temperature distribution.
Main zone and secondary zone
A ducted stove will therefore heat a main zone (the room where the stove is) and one or several secondary zones.
In this example, the living room is the main zone, and the secondary zone is the bedroom.
Heat up several rooms with your Sûti ducted stove
Number of fans:
All Sûti stoves and powers ( 8,5kW, 9,5kW et 11kW) can be ducted in option. An extra fan will be added to your stove.
Ducted power:
In a ducted stove, the power distribution between the main fan and the secondary fan is asymmetrical.
It is therefore recommended to choose a stove with a higher power, in order to better distribute the kW (heat) between the rooms to be heated.
See the graph below.
Ducted stove sketch
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.
