Christain has one and swears by it. It apears DPS have hiked up the price. Try
http://www.range-cylinders.co.uk They do an "integrated" thermal stopre/heat bank that does both CH and DHW. Get a "direct" version. Price one up.

I'm new to plumbing systems (I'm a electronics product designer) what are the differences, advantages, fallbacks of the Y and S plans, how do I decide which is right?.

S is better as Y has a mid-position valve which are more troublesome. Using an integrated heat bank, you don't need any of these plans. .[/quote]
Its only a three bedroom house, with a dining room, large bathroom, lounge, kitchen and small conservatory. Is it sensible to still use multiple zones?

More than two zones may be over top, but I would do upstairs and down as separate zones. Take both zones of a heat bank with a pump on each. The heat bank makers will install two flow and return tappings on the bottom of the heat bank for the two CH zones. The best way.
