What it is
The Ideal 172551 is a pressure gauge fitted to Ideal Europa boilers. It provides a visual reading of the pressure built up within the appliance, letting an engineer or homeowner see at a glance whether the system is holding its normal operating pressure. A reading that falls repeatedly points to a loss of pressure somewhere on the central heating system, which the gauge itself will show before any other symptom appears.
Signs this part needs replacing
- The needle sits at zero even though the system is filled and pressurised.
- The reading falls repeatedly after topping up, indicating the gauge is no longer tracking system pressure accurately.
- The needle sticks, jumps or fails to move smoothly as pressure changes.
- Condensation or misting appears behind the gauge lens, obscuring the scale.
- The boiler locks out or refuses to fire on a low-pressure fault despite correct system pressure.
Before you order
- Check the GC number on the appliance data badge against the compatibility list to confirm the gauge is correct for your model.
- Confirm the model name and variant, as several Europa models share the same casing but differ in output.
- Note the alternative part number 1178890 when cross-referencing against older documentation or supplier listings.
