Baxi Sensor Pocket Long 1/2 Inch BSP 7032579

The sensor pocket is a threaded brass well that screws into the appliance or cylinder body and holds a temperature sensor in direct contact with the stored or circulating water. This long-pattern version carries a 1/2" BSP male thread and is supplied under part number 7032579 by Baxi, listed within the Heatrae Sadia spares range. It sits in the indirect cylinder and unvented water heating family, where it allows the control thermostat or overheat sensor to read water temperature accurately without the probe coming into contact with the water itself.

• Temperature readings drift from the actual cylinder temperature, causing the appliance to run hot or short-cycle.
• The control or overheat thermostat cuts out unexpectedly, or the appliance locks out on a temperature fault.
• Water weeps from the thread where the pocket enters the cylinder or appliance body.
• The pocket is corroded, scaled or distorted, so the sensor no longer seats fully in the well.
• The sensor probe sits loose in the pocket and gives unstable readings under draw-off.

• Confirm the appliance model and serial number against the compatibility list, as the same range uses more than one pocket length.
• Check the thread on the existing pocket is 1/2" BSP before ordering, since the connection size must match the tapping in the cylinder or appliance.
• Inspect the sealing washer or thread seal at the same time and renew it if it is compressed or perished.
• Note the alternative part number 1736115 when cross-referencing older documentation or stock records.
