Sorry to drag up an old post but just wanted to confirm for others that the hack saw method worked for me on a stuck immersion heater. It took about an hour. Thanks for the suggestion.
My vented, copper cylinder has the immersion on a raised kneck so even small amounts of force was moving the boss / risking the cylinder and not undoing the immersion.
In the end I drilled two ~6mm holes and used a jigsaw to cut a triangle in the middle, then I cut two lengths back up and over and used mole grips to break a piece off. That took the force off the boss and it could then be untwisted.
I nipped the thread on one side with the saw blade but not the flange and it hasn't mattered since there's no leaks. I notice that the new immersion has a plastic seal around the top inside edge of it rather than sitting on a fibre washer. I cleaned it up with wire wool and it needed no PTFE or paste and only modest tightness to be leak free. So one day when this new one gets replaced it should be a breeze.
