What it is
The Ideal 171448 is a thermostat pocket kit for Ideal domestic boilers. The pocket is the sleeve that sits in the heating circuit and holds the thermostat sensor or phial, so water temperature can be sensed without the sensor being in direct contact with the system water. It belongs to the thermostats and thermistors group of Ideal boiler spares and is used across the Classic FF range.
Signs this part needs replacing
- Boiler temperature control becomes erratic, or the delivered temperature drifts away from the dial setting
- The thermostat phial no longer sits firmly in the pocket, giving slow or inaccurate response to changes in water temperature
- Short cycling, overheating or nuisance lockouts caused by the sensor reading the wrong temperature
- Corrosion, pitting or a split in the pocket wall
- Weeping or staining around the pocket where it enters the heat exchanger or flow pipe
