Ideal Thermostat Pocket 100mm x 7mm 003573

The Ideal 003573 is a thermostat pocket sized 100mm x 7mm, supplied for Ideal Commercial Concord Super Series appliances. The pocket is a metal sleeve that sits in the flow pipe or waterway and holds the thermostat sensing bulb or probe, so the control can read water temperature without the bulb being immersed directly. It is a serviceable item and is replaced when the sleeve becomes scaled, corroded or worn and the temperature reading drifts.

• Temperature readings drift away from the actual flow temperature, so the appliance runs hotter or cooler than the setpoint
• The boiler short-cycles or struggles to hold temperature because the sensing bulb is not seated correctly in the pocket
• The pocket is scaled, pitted or corroded, reducing metal-to-bulb contact and slowing the response of the thermostat
• The sensing bulb sits loose in the sleeve after the retaining arrangement has worn
• Overheat or lockout faults traced back to a slow or inaccurate temperature signal

• Check the GC number on the appliance data badge against the compatibility list before ordering.
• Confirm the existing pocket measures 100mm x 7mm, as pocket length and bore differ between models.
• The alternative number 1170114 may appear on older Ideal documentation for the same item.
