Ideal Flow Group Kit System 176866

The Ideal 176866 Flow Group Kit is a system-type hydraulic assembly used in Ideal Vogue S system boilers. It forms the flow group of the appliance, where the diverter valve and associated hydraulic components sit, controlling how water is directed through the primary and heating circuits during operation. It is supplied as a complete kit rather than as individual internal components.

• No domestic hot water or heating when the appliance is otherwise running normally
• Diverter valve sticking, so the boiler heats the wrong circuit or both at once
• Radiators warming when only hot water is demanded, or hot water running cold during a heating call
• Water leaking from the flow group body or from the diverter spindle area
• Erratic flow or temperature behaviour that persists after flushing and sensor checks

• Confirm the GC number on the appliance data badge against the compatibility list before ordering
• Check the model and serial number, as Vogue S variants use different flow group assemblies
• Note the alternative number 1782675 when cross-referencing against older documentation
• Inspect seals and gaskets on the flow group connections and replace any that are perished while the appliance is open
