Piano represents the evolution of the “radiator” in shape and colour. Great versatility and high thermal powers make this product ideal for both small and large environments, even with low-temperature systems.
Construction features
manifolds with a 30 mm diameter circular section
tubes made of sheet steel with a 50x10 mm rectangular section
manifold threading 1/2” Gas right
maximum working pressure 4 bar
maximum working temperature 95°C

Thanks to the high performance of Irsap Piano2 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 with piper cover kit • 1/2” air vent
