Hi,

What are the pro's and con's of S Plan vs Y Plan heating arrangements?
I am getting a new heating system and I don't know which one to go
for.

Others have mentioned just about the whole range of reasons.
I'll add that with S-plan you have some back up when things go wrong.
You can manually open the failed valve and run the other 'zone'.

Another things to remember is that if you have a HW cylinder an immersion
is a small cost which can save a great deal of hassle if the boiler stops.
