S Plan Heating Systems and 2 Port Valves – Plumbing Tips

– We all have dreams. Some of them are nightmares,
some of them aren't. But then suddenly, out of
nowhere, you wake up and I arrive like a bolt out of the blue to tell you about today's
plumberparts.co.uk video. We're gonna look at S Plan systems today and the 2 port valve that's absolutely integral in an S Plan system.

So get ready for the wildest
journey of your plumbing life. Let's just go. So an S Plan heating system is just another way of controlling where hot water goes from the boiler. It can either go to the
indirect hot water coil on the cylinder to heat hot water up that's gonna come out the taps, or it can be diverted
off to heating radiators or you can have another
valve that diverts off to underfloor heating or even another zone for another radiator, all
individually controlled by different thermostats and time clocks.

Today we're gonna look
at the very simplest type of S Plan that you can have. That is, we've got one valve here that goes off to the hot water cylinder and one valve here that
goes off to the radiators. But before we start, as ever, don't do any work on electrics if you're not happy and competent and you don't
have an electrical tester.

Always make sure everything's turned off. Always, before you remove a
wire or anything like that test and make sure it's dead, okay? Because otherwise that how you'll end up. Dead! First, let's have a little
wee look at the electrics. So with this cover off, here. Now as you can see,
sometimes you'll go to places and the wiring's just bonkers. You know, look at that, you might think, "God, where does everything go?" But if you isolate each one
like we did on the 3 Port system that I showed you a few
weeks ago in the videos, we'll be able to find out
where to remove each wire and where to put the new
one in for the new valve.

Get yourself a bit of paper
and write down everything, every colour, and what block it goes to, and where it runs off to, okay? Now, there is a common principle
with all control valves, that they need to be open and
signal the boiler only once they're open to tell the
boiler and the pump to come on. If that wasn't there, the boiler and pump could come on with the valves shut and have nowhere to dissipate their heat, could crack boiler
sections and cause leaks and basically a whole hubbub of hell. Fortunately, all the manufacturers
have thought of this, so when you do your wiring, you have your earth, your neutral, then you have a live
feed to the motor itself so when the thermostat calls for heat and everything it will send a live to this and the motor will motor around, and then it has two wires left.

Now, it's a switch,
basically, that's all it is. There'll always be a
constant live to this. This is why when you need to test for electrics in these things you need to be careful and make sure
the constant permanent live is dead, cause it's a switched live. The only way you'll ever do that is to wire set the whole system electronically by turning it off and removing the fuse. Now, you have the live supply, you have the permanent
live comin' in on one wire. When the valve opens up, it touches a smaller marker switch and sends a live back down this wire to the boiler and the pump
to tell them to come on. It's the same on all these valves, okay? Sometimes the wires on
different valves are different colours, but
generally nowadays they've tried to make them so they're all the same so it's easier for you to change.

If it is different, have
a little look at the book that was supplied with the valve and make sure the wires go
in the right place, then. Let's have a look at this
S Plant system in situ. We'll also describe that
at the office in a second. We have our boiler flow coming from here. It goes up there, just
across the top to the pump, which you can see just here, and then it comes down to this T here. Now it can either go off by this valve, off to the hot water cylinder
to heat the hot water or by the faulty valve that we're removing to the heating system. That's basically how
an S Plan system works. They're generally
controlled by a programmer and a series of thermostats. The good thing about an S Plan system is you can have as many
different zones as you like. So you can have, as I said, underfloor, different radiator zones,
different cylinder zones, things like that, which
make it a lot easier to control the services in your home.

Let's just have a quick
look, schematically, about how these systems work. Imagine we have our boiler here, with our pump flowing
water in that direction. And then we have our
two 2 Port valves here that open and close and send off water either to the radiators and
then back to the boiler, or to a hot water coil in a
hot water tank and then back. The great thing about these systems is you can have more zones that go off to different services
elsewhere and then back. That's the best thing
about an S Plan system, is that you can add things to them. And also, if there's
any problems with them, they're a lot easier to fix, 'cause you can put your
hand on that particular zone and think, "Well that's
the one that's cold.

"There's a problem with that." Also, to give you a better
idea of the electrics, we're just gonna consider the live here 'cause obviously
everything's got a neutral so we'll forget about them. So we have our live coming
into our programmer. After that, before it even
gets to the programmer, we'll take off a live,
which is a permanent live. When we look at our
valve, this permanent live just goes onto a switch
and that will feed off directly to the pump and to the boiler. That switch only ever makes
when the valve is open. So a motor open, and then click on. So how does the valve know when to open? Let's have a look at it as if the hot water cylinder is calling for heat. So, the programmer says
at this particular time that the hot water cylinder should be on. So that sends a live to the thermostat, which is effectively a switch on the side of the hot water cylinder. When that makes, it sends a live back to the motor on the valve.

That motor then motors open
and separately switches that live there that turns
the pump and the boiler on. That's how it works. The only difference between
this and a room system is the fact that a room
has a room thermostat instead of a cylinder thermostat. And that's exactly the
same way that it would work for underfloor heating, radiators,
and hot water cylinders. I hope you found today's

HOW TO INSTALL A COLUMN RADIATOR – Plumbing Tips

Honest reviews and advice Boom, Selector and all that welcoming to the days, video, Alright, anyway, what we’re going to do is show you how to fit and hang this column radiator that we’ve got here. Column, radiators are usually heavy they’re lovely to look at Their convection is not poor, really, but they’re. Much more of a modern aesthetic thing to have in your house. That doesn’t mean I like to install them Now, there’s a couple of complicating factors with this job here. Firstly, the customer actually wants this roughly here. Okay, I can use this pipe here for my new TRV on this, but the other part that’s at that end is miles away, so we’re going to have to pull these floorboards up and hopefully we’ll be able to run our pipe up to the new position. So it comes up nice and neat. The other complicating factor is the walls.

The walls here are like my friend’s dog shit, They’re soft they stink and they don’t taste very nice So anyway. The first thing I want to do is take this floorboard up and take the old radiator out of the way I’ve already shut the system down. I’M not an idiot and I’m assuming if you know how to hang or you want to know how to hang one of these. You know you have to drain the heating system down.

It’s very similar to how to hang a bathroom towel rail. There will be a link to that video at the end of this one, And also we’ll put a link on how to drain down a pressurised system. Let going to be bloody mental. Isn’t it, I’ve got our main flow return. Just here. We’ve got our feed into the radiator here and another one there And now we’ve drained down. I can probably cut this roughly back here and we can drill a new hole for a new pipe to come up.

But I’m only going to do that when I’ve hung the new radiator and I know exactly where I want it to go So the next thing I’m going to do is just rip this radiator off – Oh my God. Oh, the wheels on the bus go round and round Round and round round and round The wheels on the bus go round and round All day long.

Now, we’ve disconnected each end. I’ve also put a bit of toilet rodding in each of the holes to stop any black water getting out. We should be able to just lift this off, Oh lovely and out of the way Now all we need to do is remove our old radiator piece, So we’re going to put a new TRV and set our valves on here. You have to spigots like this. That will be what you put into the radiator, Always use Loctite on these and on most threads It’s better than PTFE. Now you put your thumb on here and hold it like that and get your first reel or two just around the front, and then you go up and then you cross cross wiggle it around a bit cross, keep wiggling it and always just crossing and crossing. That’s what locks it in it’s supposed to be a hemp and paste premix. Really, I suppose that’s the best way of describing it

And then just cut your last little bit off with the little cutter Do this to both spigots and then you can wind both of those into the radiator. And then we can look at actually what position we’re going to be. Putting the radiator in going to wind out the old plug here, and then we got this our new spigot to go in here, Get ourselves an adjustable and just knit that Right. So now we’re going to look at the difficult part of this job. Basically, these radiators hang on brackets that sit on the wall. Just like this okay, They’re, very, very simple, brackets a couple of holes in each This particular company have lovingly sent us some brackets already. These are expanding plugs Because these radiators are heavy. You need to make sure you get decent Anchorage here, Especially with one this size. What I’ll, firstly, do is I’ll get my two bottom brackets and I’ll pop ’em here, like that.

Then I’ll know how far apart they’re going to be, And that is 21.5. So I get my pencil out about to give this girl a shout Bracket. Width equals 21.5 For the next bit. You don’t actually have to have the brackets in Cause. We know the centers of the brackets are going to, be the same as the centres for these pipes here, Grab your tape and put down the centre of that pipe there. Sometimes you need a little bit of help. Someone to give you a hand. A helpin’ hand Run it down to the centre of this pipe here. That is 143.2, So now we’ve got height, equals 143.2. Now much in the same way to the towel rail, video and this one you need to decide actually where you want to hang your radiator. Now because we already know our width of the bracket, we can define the centre of the radiator on the wall, divide that by two and measure out from that, and then we know where the widths of our brackets are going to be

When it comes to the height of the radiator, I always start from the bottom. For example, I want my radiator to be 20 centimeters off the floor. You know that your bracket is going to be roughly about a centimetre and a half above the bottom of the radiator. So you measure up 21.5 centimetres Because we’ve already got a pipe here that we’re going to be going on we’ve kind of defined as to where we’re going to put the radiator on with that. So what I now need to do is I need to get my new radiator in line with that pipe down there. So I’m going to mark up where my radiator valve is By that I mean just pop in that in the side of the radiator, then I know how far the width of that has to be away from that first bracket. Let’s do that now. I know that my radiator valve is going to end there, so I also know that the centre of my bracket is here.

So if I measure over from the centre of the pipe to the centre of my bracket, I get a measurement of 11.2, Here’s the pipe I need to go on. I need my centre to be on there, so I pop that on there I measure over 11.2 and Bob’s your uncle. So what I do I just get my spirit level until my bubble is okay, A small line just on there. So now we know where our bracket’s going to be The height I’m going to define we’re going to go at about 28 Grab my spirit level to a nice horizontal line on there. So now we know where our first bracket’s going to be Now. We measure up from here 143.2 all the way to make our mark there to make sure that my spirit level’s in line so they’re not out like that. Then what we need to do is measure across from here 21.5. Centimetres Make sure that they’re both level as well and then check all your levels when you’re finished (jet aeroplane, whistles) Right. What you do is just make one little dot: Tiny ass dot. So no one will notice

If you go slightly wrong, no one can see it Then pull out my spirit, level, tiny dot, just a tiny dot and maybe one below it, And I can see the dot we did a minute ago. That means you put a dash here So now we know that is in line with that one there And we’ll make sure the mark we made earlier on is okay Get that level Now we know that’s where we can put our second bracket Now we measure across From our line here, 21.5, So simple, We do the same at the bottom cause we’re crossing the bottom at 21.5 as well.

Right, so we got our spirit level, that’s set to the right height here and just over the mark. We’ve just made draw a mark there Then the top the same A little mark there And then, if you just want to make sure you’ve got your marks right. Just check it all out with the spirit level There we go, we’ve got our four marks Now I understand what we’ve just been over is long, arduous and pretty boring, but it’s important that you check your measurements, Make sure you’ve got a good spirit level. The one I’ve got is a Stabila, It’s the best And then you’ve just got to make sure that you’ve done everything correct and right Now. The way I’ve shown you just now is slightly strange because we were going off that earlier pipe, But most of you guys are going to, have a centre line. Okay, and you won’t have your pipes there. So what you do, then, is you measure your centre line? Get a horizontal across the bottom measure out to your two bottom brackets, then follow your centre line up and then measure out to your two top brackets, using that centre line.

That’s how you usually do it, But because we’ve got this pipe here, it’s slightly more complicated! So now I’m going to show you how you actually mark up each one of these brackets and then we’re going to drill the wall, and hopefully this wall isn’t going to fall to bits because, as I told you, it’s an absolute mess So we’ll go from here And see how we get on Bob, I pop that on the cross On this round there, one right down there and I’ll do that to the next one just across here And then do that to the two bottom ones Right spot your holes get your drill. This is such a horrible wall. It’s going to go easy here: (motor revs), Just going to pop my hand on here Now I’ll know whether I’ve gone deep enough for my plug. I need to go a tiny bit more

(motor revs), That’s as far as I dare go. So what I’m going to use is the adjustable hole here, just in case I’m just going to run this up tight (motor revs). Ah, that’s great! That is great Not going anywhere Right. So We’ve got ’em all in They’re all level I’ve checked all my widths and everything They all look fine. So it’s now time to hang our radiator up, Put those two to the bottom. There Slide in at the top Pop there we go Well, that looks lovely Check. Our levels – Oh yeah, Oh my God, Yep – that is an absolute beauty. So there we go. Its all done now. It’s hanging on the wall beautifully It’s exactly where he wanted it, and it’s nice and level. I’M going to pipe it up now and I’m going to film that and you can watch that in a second time lapse. Okay,

But very quickly, there’s a cat out there eating and I want to film it eating close up Cause. I’M weird like that. Lets do that now Come on eat your dinner Right. So, there we go Piped up. I’M going to fill it up now. There’s not going to be any leaks cause. I’M amazing, I hope you’ve enjoyed today’s video. I’ve you’ve got anymore questions or you see. We’ve done something wrong or something like that. Let us know in the comments You can also follow us on Twitter and Facebook, as you know So remember. If you’ve got any questions, ask us and we will hopefully answer them in Ask a Plumber for you. I hope you’ve enjoyed today’s video. I hope you’re going to come back and watch some more

I hope you like column radiators and you think they’re amazing, And I hope that you have a lovely weekend if it is the weekend when we actually do this. So whatever weekend comes up after this, I hope you have a lovely one Yeah. I hope it doesn’t rain. I fear the latter. People Hold tight, , Honest reviews and advice..
