Specifications and potential benefits
- Suitable for buildings with 2 to 7 storeys.
- PP flexible pipes Ø 60 mm are used. These are UV-stable.
- The connection to the central heating boiler is Ø 60/100 mm.
- A support bracket must be fitted on every floor, and fixation brackets must be installed every two floors.
- Inside the property, the system is finished with a concentric fire-resistant wall plate.
