    It's a thermistor. For c/h or h/w flow temps.

    On your Performer drop down the case by undoing the 2 screws either end. Then you should be able to see them. One either side of the plate heat exchanger (edited)

    Looks like a temperature probe... and if you don't know what it is, should you be removing it ?

    Considering the OP recently had trouble running the wiring for his dashcam, the answer is a definite no.

    The probe in my boiler isn’t in direct contact with the water, it’s in a sort of void in the pipe with some white thermal paste so I could easily remove it and leave it hanging.
