Default Immersion heater

Daughter called me to look at immersion heater. The neutral connection had
failed. I trimmed back the cable and re-made the connections - but I felt a
bit un-easy as the terminals seemed quite poor - a post with a nut for N
and a small screw clamp in the thermostat for the +.

Are newer ones any better?

I am wondering if there is a better flexible that the one installed. Any
recommendations?

That's normal as far as I have seen.

I suppose that you could (properly) crimp or solder a ring to the end of
the cable and put a serrated washer above and below. The screwed
terminal for the positive should be fine as long as it is fully tightened.

Default Immersion heater

Mine seems to have some kind of ptfe sleaving over the wires near the actual
connections, but I have to say the ends on the thermostat look and feel like
ordinary piece to me but no damage has ever occurred, so I guess its ok.

There's usually two washers on the post, so that the wire is clamped
rather than screwed up. Otherwise what you describe is typical.

The 'elegant' way to connect is surely to crimp a ring terminal to the
wire.

Indeed. Though many come with a dished washer with a cutaway, and at
least that generates a more secure connection than just a loop clamped
between two flat washers.
