I live in the top floor of a flat with multiple cold water butts in the loft, one of the flats immersion safety cut out has failed again, sending hot water and steam up into the cold water butt (plastic).

My question is whether there is a fix that provides added security against a failing cut out sensor, it seems new elements have two sensors, is there a chance they have an old element?

Now I know the thing rattles and pops like it is about to explode when this happens, so most people hear it and turn it off, but the person in question spends lots of time away and I had to resort to pulling their main fuse.

Is this flat owned or let/rented?
You have done the right thing, by isolating the system.
And it also sound like the safety devices have failed, the owner or the responsible person for the flat must be contacted and they should ask a competent plumber to assess/repair the issue.

My concern is that a plumber will just replace the temp sensor, which will break again at some point (as this is what appears to have happened).

Are there multiple fail-safes/sensors that can be installed, or other fixes that will ensure this won't happen should a single sensor break?

I may sound like the annoying neighbour, but the tank is above my bedroom and I do not feel safe.

All immersion thermostats sold since 2004 have to incorporate a safety cutout, try to make sure your neighbour replaces any remaining stats with the new ones and you should be safe .

You would need to ask an electrician about the following: It may be possible to wire the immersion in series with a cylinder thermostat (possibly using a relay). As I said, ask an electrician.

My main reason for suggesting an electrician, is because I don't think there is a need for a tertiary cutout, but if the OP thinks it is needed then there is probably a need for a relay. That is what the OP asked and I was giving a reply that I hoped included due diligence. A sparks would be best to give professional advice on this.

Why the question?
