Ideal Mini C24 / C28 Flow Group Kit – Refurbished | Part No. 172509

The flow group kit is the hydraulic management assembly at the heart of an Ideal Mini combi boiler — housing the diverter valve, bypass, automatic air vent, and circulating components that control water distribution between the central heating and domestic hot water circuits. When it fails, the most common symptoms are loss of heating or hot water, inconsistent flow, or a seized diverter valve that prevents dual-mode operation. The Ideal Mini C24 / C28 Flow Group Kit (Part No. 172509) is the correct OEM-specification replacement for the Mini C24, C28, HE C28, S24, and S28 models, restoring full hydraulic operation and dependable boiler performance.

This is a professionally refurbished genuine Ideal component. Each unit is cleaned, inspected, and function-tested to original manufacturer specifications before dispatch. Replacing the complete flow group assembly in a single operation resolves diverter valve faults, air lock issues, and circulation problems simultaneously — restoring the boiler to full working order efficiently.
