Biasi Riva Compact HE M96.24 SM/C Flow Group Kit – Refurbished | Part No. BI1141504

The flow group kit in a Biasi Riva Compact HE or Garda HE M96 boiler is the central hydraulic assembly responsible for managing water circulation between the CH and DHW circuits. It integrates the diverter valve, diaphragm assembly, and bypass — all in a single serviceable unit. When the diaphragm perforates, the valve seizes, or the assembly degrades, the boiler typically loses the ability to switch between heating and hot water modes reliably, leading to intermittent faults or total loss of one function. The Biasi Riva Compact HE M96.24 SM/C Flow Group Kit (Part No. BI1141504) is the correct OEM-specification replacement, restoring full hydraulic function across the M96 range.

This is a professionally refurbished genuine Biasi component. Each flow group kit is stripped, inspected, and function-tested to original manufacturer specifications before dispatch — providing complete hydraulic circuit restoration at a significantly lower cost than a new assembly. The higher price for this flow group reflects the complexity of the complete M96 kit versus a standalone diverter valve replacement.
