Wiring diagram

Former Community Member
Former Community Member
Anyone out there with a great mind for heating systems, care to draw me a wiring diagram ?


There is a

-warm flow oil boiler 

-Immersion 

-pipe stat 

-UFH Valve

-Manifold(8 zones)

-Hot water valve

-Hot water circulation 

-Towel warmer valve (stat is what’s on the towel rail)

-Upstairs heating valve

-2 x 2 channel Honeywell programmer

-1x 1 channel Honeywell programmer

-1x stat for upstairs radiators

-stat for each ufh zone 


Any advice on what I can use to get this all linked together, currently looking at S plan but I feel someone with experience with similar system  may give some better guidance

    Well if it were me, I'd leave a fused connection unit fitted with a 3A fuse next to the boiler and get the plumber who designed it to wire it up.

    There are that many different variations these days, especially with all the UFH stuff combined with rads/hot water cylinders etc that I no longer do any of the sub circuitry for CH systems.

    S plan is good as you can have as many zones as you need, each with its own room stat. The tank stat will control a motorised valve for hot water temperature control. Presumably the under floor heating also has its own zone motorised valves and stats. Just break things down into sections and it all becomes clear.

    Just be sure to record the way you have done it - because guess who'll get called back if it goes faulty?

    I've done one wet UFH job and it was a nightmare. After that I said never again.

    And on the other hand, I love doing such stuff.

    Few people want to touch it, I really dont know why, it isnt difficult.

    I've even done systems and told the plumber he hasnt got enough valves on - if I'd have done it as he planned, the radiators would come on every time the UFH comes on.

    There’s so much happening with this system. I’ve broke it down , think I’m fine with the upstairs radiators .


    towel warmers I would assume you just connect the live out (programmer) with the brown of the valve? As no stat 


    it’s the rest which has stumped me. There wasn’t any stat on the immersion? Other than its power terminals? How will this be tied in and where?

    If by hot water circulation you mean there is a long run of hot water distribution pipework, so a circulation pump is going to be installed with a hot water return pipe to allow the hot water to circulate so that hot water can be drawn off at taps almost immediately without wasting water and heat, then it’s usual practice to fits separate time  clock to control it, so it’s not running all night and at other times when hot water is unlikely to be used.

    -stat for each ufh zone 




    Its a S Plan + system you want.

    Disregard the boiler, as all that'll need is a Live and switched live feed, probably.

    Immersion is totally separate.

    Pipe Stat - presumably a Frost stat? Clarification needed.

    UFH Valve, just one of the S+ valves.

    Manifold, should be straightforward, the manufacturers install details will tell you what to do, possibly has 8 floor/room stats?

    Towel warmer valve? Never heard of that, and seems to be a strange choice to me,is the towel rail really getting its own S valve? Surely an electric 250watt element woudl be far better. If there is a separate valve for it, then its just another S+ valve. All easily wired in.

    Hot water valve and circulation, one S valve on the S+ system and the pump.

    Upstairs heating valve. Just another S valve.

    2 Programmers, presumably one for the CH and hot water, one for the UFH. Why not just one 3 channel programmer?

    Stats, whether room or floor. One for each zone. So, upstairs and downstairs CH, each area of the UFH, but they may be included in the manifold kit.

    You will definitely need a water tank stat. And a pair of 2G connection boxes. One may suffice, but it'll be tight.

    Thanks for that Andy.


    That sounds about right, as there is a single Channel controller.


    My next question would be how does this all tie into the wiring diagram? 


    Live out of channel programmer go to Brown of the hot water valve?

    Can you send me over an Splan + wiring diagram? I can’t find one.

    Pipe stat, is frost stat. Should of stated. 


    Towel warmers are on a valve, plumber said this is a preferred method of his. With this not having a stat other than the ones on the towel rails, do I just go straight from programmer to the valve?


    Ive had a brief look at the manifold, but they don’t have anything about valve in there? The instructions are in foreign, no english whatsoever 


    What is the S valve? You mentioned along with the hot water valve
