Ideal Flow Regulator 26kW 179126

The Ideal 179126 is a flow regulator rated at 26kW, used in the hydraulic circuit of Ideal's Vogue generation of combi and system boilers. It governs the rate at which water passes through the appliance, which in turn affects how the boiler responds to demand and how steadily it holds its operating conditions. The part carries the alternative number 59200808 and is listed under part type FLOW REGULATORS.

• Hot water flow at the outlets drops noticeably compared with the appliance's normal performance.
• The boiler struggles to hold a steady temperature, with the delivered water cycling hot and cool.
• Flow-related fault codes appear on the appliance display during a hot water draw-off.
• The regulator body shows scale build-up, debris, cracking or deformation once removed for inspection.
• Water weeps from around the regulator or its connections.

• Confirm the appliance model and GC number against the compatibility list, as the same regulator number is used across several Vogue variants.
• Check the number stamped on the regulator being removed; 59200808 and 1783059 may appear in place of 179126 on older stock.
• Inspect the seals and O-rings on the removed regulator and renew any that are hardened, flattened or damaged before refitting.
• Isolate the water supply and depressurise the appliance before starting work.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
