Is it usual for programmers on a Y-plan system (or even S-plan) to
allow for HW priority? There seems very little point in buying a
quick-recovery cylinder and finding that it still takes about an hour
to heat the tank because all the radiators are on!

No - neither Y-Plan nor S-Plan provides for HW priority. They both allow for
HW and CH to be on concurrently with *equal* priority.

W-Plan does, of course, give HW priority - but can keep the CH off for a
very long if you *haven't* got a quick recovery cylinder.
