This video is just for advice. Always make sure that you use a qualified electrician or somebody who's competent to do wiring.
My name's Allen Hart, and I've been asked, Jack has asked and a few other people, how to wire heating systems. So, in this video I'm going to show you how to wire an underfloor heating system. We'll have a look at this wiring centre, and I'll do a step by step video on how to wire it, where the wire's go, et cetera, et cetera. All right, let's have a look at it now.
We've got our wiring centre here now, I'm going to wire this up. So, I've started with the mains. This is our live, our neutral, and our earth. This would normally just go to a spur and then what we'll do, we'll move into these different terminals here and I'll show you how to wire each individual section of this.
I've got this wiring centre, we need to put a link in there. It's this timer there, and very important we put that link in, otherwise it won't work. This is if you've got a separate controller, separate timer, then you can wire it into this. But in this particular case, we need to put a link in, because we're going to have a programmable room stat.
Now we've got the pump wires, and the pump wires go in there. And it clearly says it on there, pump, so it's very, very easy to understand. And that's just going onto our pump there. And that's just got a plug in connection on there.
Now we've wired the zone valve into this, so we've got the zone valve there. And we've got our orange, our grey, our brown, our blue, and our earth there. It does say it on it as well, so it's clear and really easy to do. Now we've wired the switch live to the boiler, so it's the on off. So, this is what your link would be for your room stat. And that's wired in there. And again, it shows you there, boiler, so it's really, really easy to see and do. It's also, the reason, one of the main reasons you'd use this wiring setup is it's then got its relays built in.
So, when you get your power back down this orange, it won't back feed on your pump. What I've done here, I've just put a link in. You can put a link in, it could be in any of these here, but you're linking the live terminal and the L1. That, if you're going to put a room stat in, this is where the wires would go.
One thing to bear in mind with this, it has about an eight minute delay, so when you do turn it on, it will not work straight away. That's just something to bear in mind. Shortly I'll wire the thermostat on here as well, I'll show you how to wire that in.
To wire the controls up on this, again, it's very, very easy. It's all labelled. I'll turn it that way around, so we've got our neutral, which is obviously the blue, then we've got our live which is our brown, and then we've got L1, which is a switch to live. And what we'd normally do is we'd normally sleeve that with some brown sleeving. I haven't got any brown sleeving for the purposes of this video, but yeah, we'd normally have brown sleeving on that. Ill show you how to wire this now to the boiler ... not the boiler, the actual wiring centre.
That's our thermostat there now, that's just temporary there. I'm going to put a nest on here, so what I'll do is I'll do video on how to swap it over for a nest as well. But there are our wires in there. So, it's very clear. If we look on that one, it's easier to see, it's got neutral, it's got live, and it's got a switch to live there. As you see, neutral, live, switch to live.
As I say, normally we'd have some brown sleeving on there, but we don't have any. So I'm going to switch this on shortly, and as I say, this will have an eight minute delay on this. I've wired it all up now and we've got the controller working. See the wire's at the bottom, this is just temporary just to show you how to do it. If we turn this up now, this will then call for heat. It took about five minutes last time for this to fire up. That's how you would wire your wiring centre for your underfloor heating system. This heating system, this is the Beneath Heat system. That's Beneath Heat Manifold. And then obviously it's got the pump and all the bits there. And that's the Beneath Heat wiring centre. I'm sure there's other wiring centres that are similar, but this is the one that I've used on this particular instal. - Навчання та стиль
You have such simple videos. No waffling full of tips and I learn new things every video. You dont even have an intro no fancy editing. Everything is just basic and full of information. Thanks for being such a help to the apprentices :)
Thanks Alan...this video was very helpful, as my installers have not used the wiring centre because they said it wasn't need - and clearly it is, especially with a 3 zone UFH system.
Great videos. I’ve a beneath heat system so this is perfect. Thanks - I wanted to see how to replace the solenoid valve but I worked it out from your video
Very good tutorial 👏
So informative ❤
good video.its helpful. thanks
Thanks.
Hi Alan great videos. I'm doing and ufh exactly what your showing with a combi and rads. The question I have is do u need a wiring centre od can you just use a connection block. What I want to know is what's the advantage of the wirring centre.
Thank you for you video - it is concise and useful! ...but it would help a lot if you would start with specifying what wiring center you use here...looks like Reliance 8, but not sure.
Great video, easy to follow and straight to the point! What make/model wiring centre is that?
Great video thank you for sharing. I don’t think I saw a connection from the wiring centre to the boiler? Apologies if I missed this.
hello thank you for the video. could you please show the combi boiler where to connect the wire
Hi Alan - thank you for the video. When you say the switch wire goes back to the boiler where does the sw get terminated in the actual boiler itself. I’m wiring a boiler next week and it had ufh, nest thermostat for the rads and wondering where all these are wired into the boiler. The plumbers there tomorrow so is opening up the boiler for me. Will it have separate ufh and central heating terminal blocks. Thank you.
hi Allen thanks for uploading many video regarding boiler & heating , i just watch this you tube video regarding this underfloor heating system, it is very helpful for new gas safe engineer, im gas safe ,can you confirm what make and model underfloor heating wiring central are using it in this video ? it is very easy to installed so let me know as soon as possible please ? thanks
Hi Alan what make and model wiring Centre did you use in the video you made it look so simple great video thanks.
Hi Alan,
Great video, please keep up the good work!
The 2 core wire labelled boiler where does this wore into the other end?
Does it wire into wiring centre at the boiler?
Thanks in advance
If i’m using an s plan unvented system does this wiring centre allow me to connect the hot water and heating to this to ? Or do I still use the wiring centre that I have (Honeywell )well one for hot water and rads . And a separate wiring centre for UFH 🤔thanks mate
Thank you Allen for posting this video. By the way this only video i could find on youtube for wiring centre. As I am doing up my house decided to have wet underfloor heating. it is two loops manifold with latest grundfos pump. my electrician has failed to connect wiring centre to boiler following diagram i showed him this video still didn't work. wiring centre is very similar to the one on this video. are we doing something wrong ? he has used link for timer as shown and also waited for 15min but still boiler wouldnt get signal. also do i need zone valve to control flow as i have worcester boiler quite powerful so i have 4 rads upstairs and downstairs underfloor heating only. so i have boiler, 2port manifold with grundfos pump and ports are controlled by electronic actuators and lcd stat all to be wired. I'd appreciate any advice on this. thank you in advance.
Hi Allen you say wiring centre is a beneath heat
Wiring centre but there not showing this wiring centre on the site looking for the installation diagram if you would be able to help
Regards
Les
Hi Alan, do i need a system inhibitor in my ufh system and if so how do I add it to the system ? Thanks John.
What about when we switch off. Do it still take minutes to off pump
Hey Alan what if u whant to add an extra zone valve?
Hi great video, I have a question you put two zone valves in one for underfloor heating and one for the radiators, where does the wiring for the zone valve for the radiators go I missed that bit
I was wondering the same
Can you do this without a wiring centre
Hi , I'm not a plumber or electrician but I'm a vehicle mechanic that likes to mess!!!! Anyway I zone controlled my entire house around 8 years ago with fantastic results but I've now used one of the zones from the conservatory to run a wet underfloor heating system that's gone into an extension I've built that's replaced the conservatory, my question is that I don't want the ufh pump to run with the existing zones until it's called for. I know I could isolate it using a contactor but is there something that's designed purposely for the job or is this controler what I need? Thanks in advance.
Need a 4 core cable for the room stat, never ever sleeve the CPC wire it's against regulations FYI otherwise brilliant video
Hi can I pay you to do stap by stap wire my underfloor heating to my ideal boiler as I think my plumber messed it up
please show me where you connected the cable to the boiler
Hi Alan if your adding underfloor heating just one zone do you just pick the boiler switch side and put into the wireing centre as it already as a normal thermostat thanks Mike
you would need two zone valves so you could controls rads and ufh separately. Thanks.
Hi Alan, great videos. I’m in the process of installing a similar setup. The video shows you wiring up the port valve for the UFH but not the second port valve and thermostat for the radiators. Appreciate if you could explain how this would be wired into the wiring centre. FYI I have a Heatmiser UH4.
Many thanks
Ditto. I would also really appreciate more info on this detail
Did you manage to figure it out, I am similar situation, have part UFH and part radiators on the ground floor, looking to see how to set it up
Hi Allen I also got stuck at this point can you explain how second zone valve and thermostat will be wired in. Do you need secondary wiring centre as can be seen next to the boiler ?
Hi Allen
You only wired one of the two Port valves in the wiring centre, where does the other two port valve wire into? Thanks

Hello,👍 were you intal boiler ca I put heating pump?
Presuming there are strain relief straps and maybe grommets for the wireing center. ( I get that this is a demonstration how to scenario) your pipe connections and electric connections are night and day. (All my plumbing and half of my electrics look a bit Friday afternoon)
I was looking for an 30 to 90 minute video of the process ,i know they can take a while to render and longer to upload, my computer is getting used to72hour run times. Or 4 hours editing for sub 10 minutes of footage.
You've not mentioned what the cost would be for a person wanting to get some of this warm floor action.
Look forward to seeing the playlist grow.
Hi can you add under floor heating to any system or has it got to be added from the start of a new install.
I am adding underfloor heating onto the heating system in my house. Normally you could add it. Thanks.
Hi Allen I’ve seen few comments about how to wire in the secondary zone valve and thermostat into the wiring centre. Which I have also asked in one of the comments. Can you please go into more detail how it will be incorporated within the same wiring centre please. Or we need secondary wiring centre as it can be seen located next to the boiler?
I will do a new video when i get chance. Thanks.
BS7671 wiring regs say that any green/yellow wire cannot be sleeved to turn it into anything else. To do so is considered naughty.
plumbers don't care about electrical rules

If your a plumbrriacian then anything goes🤣🤣👀🤓🤓🤓🤯🤯
Hi Allen, I have the same wiring centre which had been left unfinished by the installers. Could you explain more about the BOILER switch connection and where those wires need to go? You mention it being a link wire? Thanks
Will do, Which bit do you need to know? Thanks.
Allen Hart hi just want to know how to connect 2 wire from under floor heating wiring centre to boiler mean where to connect on boiler thanks
Hi Allen, can you fit the final floor finish directly onto the matts and pipes or do you need to lay a screed?
Thanks
joe fowler I think I will tile straight over the top. 👍
@@AllenHart999 thats good, so the overall system really doesn't raise the floor height much at all. 👍
@@joefowler9600 The system is absolutely brilliant. Very low profile. Thanks
Great video really helped me could you tell me what wiring centre this is please thanks
Saswell
Hello mr Allen, dose this system need boiler programmer?
Yes.
Good video one question can you wire a two wire thermostat to this system and if so how ?
Yes, I will try and do a video. Thanks.
Hi thank you for this video. Very interesting. What is this wiring centre called please? Can't find it anywhere
Underfloor heating wiring centre, one of the most common is Heatmiser
Something like Saswell SCU209-LED
I just moved into a property and I can't find the thermostat, also I am not sure how to turn the heating off and on?
Sooooo confusing 😵
Thanks for the question but how can i help?
👍🤓👍🍰
Great video but as a Sparky please include earths in the wiring to the devices. It's a plumbers idea that just because the thermostat and devices are double insulated, they don't need an earth. The wiring between, all must incorporate an earth...
As in central heating jb
What is the purpose of the 8 minute delay?
It just happens when you first turn on the mains to it. Not really sure why. Thanks.
@@AllenHart999 So after the first power up there is no delay?
@@Sash_Window Just checked it now and it does it when you turn stat up as well. Maybe it's the stop it coming on and off and cycling. Was about 3 minutes. Thanks.
Just checked it, Still has a delay, It was around 3 mins. Thanks.
