[QUOTE="Geoff1946, post: 496911, member: 28452"] The neutral of the immersion "burning out", with a new heater can ONLY be due to the connection not being properly made. Perhaps the old cable was oxidised? Try again, preferably with a new piece, either cut back or replaced. At least that will give you hot water. Your other problem requires an electrician with test gear. Sorry, just re-read it, only the thermostat changed, not the actual heater. I would replace the lot. [/QUOTE]
