The strap on thermostat is a good idea though, and if there's no
improvement with the new tank, etc, then I'll definitely give that a
go.

Be very careful if you go the strap-on stat route. Many stats of this type
are only designed to switch cental heating valves or pumps - and can only
handle about 3amps - making them totally useless for switching an immersion
heater. The Horstmann HCT2 stat sold by Screwfix for 8 quid appears to be
able to handle 16 amps, so may be ok.

Even so, it probably doesn't meet current regs with regard to having to have
a manually re-settable safety stat in addition to the one providing normal
temperature control.
