Hi all

Does anyone have a link to a comparison of these systems.
Struggling to see the advantage of S Plan, although I have seen a number of
posters supporting this.

Currently I have S plan, but will have boiler replaced shortly and need to
relocate solenoid valve/pump in existing system.

Currently the program is set for 1 hour water heating only before main
heating phase only at start of day.
1 hour water heating mid-day.
In the evening we have 6 hours heating with 1 hour water heating included.

Would a Y plan system compromise this in any way or am I missing something
here?

TIA

Phil
