My existing indirect hot water cylinder is leaking at the bottom and needs to
be replaced.

There is a thermostat strapped to the cylinder for the central heating boiler.
The cylinder is not foam covered so the thermostat and its strap are in direct
contact with the copper surface.

Any replacement cylinder will be foam covered. What's the best way of attaching
a thermostat so as to minimise the removal of any foam?

If it is, it should have an inbuilt stat..

I can think of three options:

You can order a cylinder with a pocket fitting to take the bulb from a
capillary thermostat. This results in the smallest amount of foam
removal.

The RF cylinder thermostats have quite a small sensor which is strapped
onto the cylinder.

With a conventional strap on thermostat, mark around it on the foam and
cut out that section only. The brackets have lugs near the top to
avoid the strap having to lay against the cylinder.

Just fitted one when I had a new boiler installed. I used a scalpel to cut
fairly close in around the body of the thermostat, and then sliced in
diagonally in the foam that was to be removed, IYSWIM.

Make sure you get a cylinder stat which is secured with a wire band that
goes right across the top of the body of the stat. I had one on a previous
property where the stat had two little wings down at the 'face' of the
metal contact area, so it was necessary to cut lead-in channels in the foam
either side of the stat.

If it is, it should have an inbuilt stat..

In an ideal world......
