Thanks to the high performance of Irsap PIANO Horizontal radiators, the ideal Δt for low temperature projects is Δt at 30°C.
For Δt different from 50°C use the formula: Q=Qn (Δt / 50)n
Standard equipment
- wall fixing systems with screws and anchors
- 1/2” blind plug
- piper cover kit
- 1/2” air vent
