What it is
The Ideal sheath (reference GUA0005) is a tubular probe pocket used on Ideal Commercial appliances. It holds a temperature sensor or thermostat probe in position against the water or heat exchanger surface while shielding the probe from direct contact with the system contents. The sheath measures 15/16 inch in diameter and 147mm in length, and is supplied under Ideal part number 171788.
Signs this part needs replacing
- Temperature readings that drift, spike or sit outside the expected range for the appliance
- The boiler short-cycling or locking out on a temperature-related fault code
- Visible corrosion, pitting or a perforated wall on the sheath body
- Heavy scale or sludge build-up on the sheath, reducing heat transfer to the probe
- Moisture tracking into the pocket, causing intermittent sensor readings
Before you order
- Confirm the appliance model and, where shown on the data badge, the GC number against the compatibility list
- Check the existing sheath against the 15/16 inch diameter and 147mm length quoted here before ordering
- Note the manufacturer reference GUA0005 and the alternative number 1780094 when cross-referencing the old component
