Yes we all go droopy in the heat if not supported, what?
I'm not convinced about this to be honest. I remember when we first moved
in here and had flow issues in the bath my father trying this sort of thing.
It did not work and it found a few pin hole leaks in the plumbing under the
bath which in the end needed the pipes replacing and so we got a new bath
and new pipes in the end. The question I always wondered about was how come
the particular pipes were coated in scale inside but the very old but wider
ones in the loft down to the bath and from the cylinder to under the floor
did not though clearly they were older by some years.The plumber at the time
said often life is like that, and shrugged. This was many many ears ago in
the 1960s.

The flow to my bath has dwindled over the years, it's a conventional
vented cylinder and 3/4" copper pipes, is there likely to be any
benefit in dosing the cold water tank with sulphamic acid and then
recirculating through the bath tap connection with a pump?

A tub of fernox DS3 will make enough gallons to fill the tank and the
cistern, so yup recirculating with a pump for a few hours should do the
trick. Keep the immersion on for better performance (but don't let the
cistern get too hot if its plastic - they can go droopy if not well
supported)
