Zone valves on heating system

[Sureheat]

Hi all im going to be upgrading a heating system,installing extra rads upgrading pipe work etc.The boiler is a worcester 400 rsf electronic higflow.layout is boiler has integral programmer for hot internal store and for central heating.What i want to do is to have two zones for the central heating with two zone valves obviously , hot water programmed from horstmann 3 channel programmer.anyone know how i could go about getting my sparky to wire this.Getting rid of internal programmer and using only external horstmann one.Only one room stat , know i should have two to control both zones just cant fathom how to wire this thing yet

Any help much appreciated.

or is this a one for the sparky forum

so whos wiring it, you or the sparky.make sure you get a sparky who knows how to wire heating systems.

A sparky who understands heating controls and principals is a very rare beast indeed!

I'm in Durham, not too far!

How about

not sure on your set up but that's what I worked out for some one else. See here . I am sure any good spark would modify wiring in same way as I have not sure why this was moved from electrical section?

A competent electrician will be able to adapt this diagram to suit your system.
