Ideal Flow Regulator 40 KW 176873

The Ideal flow regulator (part 176873) is a 40 kW rated hydraulic component used across Ideal's domestic and commercial boiler ranges. It sits in the water circuit and controls the rate at which water passes through the appliance, helping the boiler hold a steady flow and a stable temperature during draw-off. It is a serviceable spare, intended for replacement when the original regulator becomes restricted, worn or damaged.

• Reduced or inconsistent hot water flow at the outlet, with the tap or shower never reaching its usual rate
• The boiler cycling or struggling to hold a steady domestic hot water temperature
• Visible scale, sludge or debris on the regulator body, seat or inlet
• Water weeping from the regulator body or from its connections
• Measured flow rate drifting away from the value set at commissioning, even after the inlet filter has been cleaned

• Check the GC number on the appliance data badge against 47-348-97 to confirm the correct variant
• Compare the model and serial plate with the compatibility list, as the same part number can be listed against more than one Ideal range
• Cross-reference the alternative number 1782523 when checking older stock, manuals or job sheets
• Inspect the seals, O-rings and washers on removal and renew any that have hardened, flattened or perished before refitting
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
