S plan wiring - made simple

IMPORTANT
Please do not attempt to work on heating or electrical installations unless you are under the Direct instruction of a qualified person.
In these diagrams the CPC is left off the drawings for clarity. The CPC must be connected to all equipment/accessories. In the case of class 2 equipment (not requiring a CPC) the CPC should be suitably terminated in a connection block

I’ve seen quite a few videos of s plan wiring on KZbin but none have provided such a clear and logical explanation as to the different components and how they link. Makes what can look like a jumble of wires pretty straightforward. Thank you for taking the time to make this

[@JPElectric]

Thank you Steve

[@dansheppard2965]

Clearest S-plan wiring intro video on KZbin. Thank you!

[@JPElectric]

Thanks Dan

I follow john ward and his videos are very simple and useful but i must admit this chap has made things so simple by easily breaking everything down. Amazing video thanks.

[@JPElectric]

Thank you very much for you comments. Good to know it helps.

He is very good JW, this guy seems reay good too.

[@andrewtaylor2591]

brilliantly illustrated, thank you. I've always been petrified off any heating system other than a simple combi! so informative.

[@JPElectric]

Thanks Andrew, really please you found it helpful

[@Chris-uu6dg]

Hi, thank you so much for your very helpful and clear instructions, your diagrams and your explanations are so well broken down that I have at last understood how it all works!!! I have watched many other You Tube videos about S Plans before yours and they make it so much more complicated and I was never really confident I understood, but after watching your video it suddenly all clicked together. Many thanks and I just subscribed looking forward to other videos from you.

[@JPElectric]

Really pleased you found the video some help, and thank you for a really nice comment.

[@RavsiSingh1]

Thanks for the super clear video. Explanation / diagram of the two port valve workings is one of the best I've come across on KZbin!

[@JPElectric]

Thanks Ravinder, I really appreciate your comment.

[@jameshansing5396]

Great video! Made a potentially complicated - or certainly seems so at first - subject feel very simple. A skill in itself.

[@JPElectric]

Yes, going to do a Y plan video soon.

[@johanburger6109]

@@JPElectric great video jp, just one question, if I look at your drawing of the overview wiring. There is a live coming to the boiler from the junction just above it. What is that for? The live below the boiler is easy to identify as it goes directly to the 2 switched valves

[@JPElectric]

@@johanburger6109 Thanks for the comment. Boilers often have a permanent live as well as a switch live. The permanent can be used to power the pump overrun function , which helps cool down the boiler. But it all depends on what boiler you have. So its very important to read the instructions for the boiler. But If you are wiring a system, I would alway make sure you have both a switched and permanent live to the boiler.

Really clear explanation of s-plan wiring, thank you.

[@user-iq6xt8nn5r]

Brilliant, thank you so much for taking the time to do this, this is the clearest explanation of S plan wiring, and electrical wiring in general tbh, I have ever found.

Thanks Adam really appreciate you comment

[@JPElectric]

Thanks John, hope it helped

[@thomassmith3711]

Great video. I am about to carry this out. Do you typically remove the links and loops that come pre installed on a boiler. Many of them relate to other control methods that I don't believe are relevant when wiring an S plan.

[@JPElectric]

Hi Thomas thanks for the comment. I can't really advise on specific wiring issues. as I don't have knowledge of your system. Some boilers do have links that are removed when a stat is installed for example. But I would advise caution. if unsure , contact a local heating engineer.

[@jaymxult7142]

[@JPElectric]

Thanks Jay

[@Sirjohnwilliamuk]

Dear friend thank you for this brilliant work. I am a bit puzzled with pump 2 hot water is missing a neutral. is that just a typo?

[@peterhughes8327]

In the house I’m wiring it’s bungalow I’m using the s plan for heating I’m only using one time clock and I’m taking 2.5 swa from booster clock to the boiler is that the right way or am I missing something

[@bimiuk4051]

Can u also create a X PLAN wiring diagram for the Opentherm and PDWH?

[@TheDsong]

So does the hot water 2 port valve not need a neutral?

[@JPElectric]

Hi Duncan. The two port valve has a neutral for the motor

[@TheDsong]

@@JPElectrick thanks

[@user-fs3pb8dn6e]

the only thing I don't understand why room thermostat and cylinder stat on the 4 position and not on the 3 position?

[@JPElectric]

Not quite sure what you mean?
