So, why was it overheating? Only thing I can think of is that the
switching temp moves after a period of operation.

Does this sound plausible?

bimetal stats can become sticky, sometimes sticking shut.

It isnt a bimetal stat.



Um, I think actually it is.

That's an overload protector, not a stat, and so it can't have stuck shut
and caused the towel rail to overheat.



Maybe, but it's being used as a stat (and functions as a stat).
There is no other stat in the heater. The only other component in
the heater is a thermal fuse for "last ditch" overheat protection.

But you said that it still switches, just at a different temp,
so it can't be sticking shut.

error in logic captain. And a bit sketchy on facts.
