UNDERSINK WATER HEATER INSTALL – Kingspan Undersink Heater
63 Comments


– Hey guys, James here
from Plumberparts, UK. We today are going to be fitting an under sink water heater
in our little kitchenette that we’ve got here today. The under sink water heater that I’m fitting is a Kingspan. We’ll have a look at the actual
details of that in a minute. So we’re going to be talking
about pressure relief. We’re going to be talking about expansion. We’re going to be talking about how we actually just fit it in a tight space because it’s under a sink, it’s always gonna be a tight space. So I’m going to show you
from start to finish, how to do this job and what you should be thinking about as
and when you’re doing it and how to make your pipe work look nice. How to make it nice and neat. That’s what’s really important. Please follow us on Instagram, guys, ’cause I do lots of stories
that look just like this. – [Voice Over] Why’s my van
got top soil in it, man? – And also follow us
on Facebook, Snapchat, Instagram, twitter and definitely the biggest thing you can do is subscribe. So, without further ado
let’s get on with this video and let’s get on with the job. See you soon, guys. Hold tight. (upbeat music) So first up before we
begin, let’s just unbox this lovely little water
heater we’ve got here. Polystyrene typical, let’s
get that out of the way. We’ve actually got the main body of our water heater just here, like so. Oh, dear. Now we want to be careful
when we put it down like this because the actual nobs and
dials for this water heater are on the front. Let’s whip this off and then we can have a very quick look at
the water heater itself. So, we’ve got our temperature
adjustment on here, you can hear the thermostat
clicking on there already. We’ve got our on and off switch as well and that’s pretty much it
really for the front of that, really, really simple. The hot and cold end
denoted by, guess what, blue and red, absolute crackers. And we’ve got our clips at the back for our wall bracket, so that’s that. Whatever you do, ‘kay,
when you put that box down make sure you check underneath it. Check underneath because if you lift up the last little bit of polystyrene, you’re gonna find underneath, number one, heres your bracket, your wall bracket and also we’ve got our high pressure
relief valve here as well. Just want to briefly
cover two types of kit that you can get with this
particular water tank. You’ve got the kit that mains pressure, that is up to 4.1 Bar on the incoming and all you get in that kit is your high pressure relief valve which is what this little beast is here. If your system has got a
pressure of above that, if it’s above 4.1 Bar, you’re gonna get a little 2 litter expansion
vessel like we’ve got here and you’re also gonna get
a pressure reducing valve. You also get a check valve as well, guys. So that’s a non-return
valve and normal parts. So, now we know what we’ve got here, I can talk about the actual connections and the bits you need to get to make sure that you can actually
start to instal this. Now guys because I’ve
done a water pressure test on here I know that it gets up to about 7 Bar at night which is pretty high. Just in case here I’m gonna be popping this little clip on, that should be fine. So, what we need to do,
although they’ve supplied all this stuff here,
they’ve supplied the bracket and they’ve supplied all this
little bits and bobs here. They haven’t supplied the irons okay? So what we need to do is just go out, I usually buy one more
iron then what I need and then when I get to the next job I’ve got an extra iron in the
van I can use on the next one. So, you’re gonna need I think
three female irons to 15 mil, and three male irons to 15 mil as well. So, I’m gonna pop these all on now, using my usual bit of lock tight, what I’m gonna do is
make up all the fittings that I’m gonna be using
on this job right now and then I’ll be able to
go to the under sink area, we’ll talk schematically
about what we are gonna do and then I’ll show you the actual area where we’re gonna be fitting it and how we’re gonna be doing it. And how my thought process is of carrying out that fitting and doing it. (mellow music) Alright then guys, now that we’ve got that on there and all this is ready to go, let’s have a look under
the sink where we’re actually going to be
installing this beast. This is where the video gets fruity. Hey guys, and welcome to my humble abode. We need to think about a
few little things here. Now a water heater doesn’t
weigh a lot when it’s empty but when it’s full of water it can weigh quite a few kilos, so
usually I go for trying to mount it on the side bit of wood because it’s usually a lot thicker. As you can see I’ve already first fixed our pipes here so we’ve got our cold here, this is our cold main in that way, and then we’ve got out hot
back out this way, okay? You may also, of the
beady eyed natured beasts who are watching at the moment have noticed that I’m
feeding the hot pipe up to the tap here in this kitchen sink but I’m also running it ’round as well to the small little toilet
that we’ve got next door where I fitted that Victory
toilet a few weeks ago. So, let’s have a little think about the considerations that you
need to sort of think about, worry about when doing this sort of job. Number one, these. These are the first things
you need to look at. Have a look at where your electrical supply is going to come from,
have a word with your sparky to make sure that you can
get everything sorted out and that it’s going to work okay. The instructions for one
is pretty comprehensive they come out pretty well, they’re not complete gobbity gook. They give you really good
dimensions for the widths of the 10 or 15 litre ones,
so if you’re not sure, you can go online and find out
the sizes of these already. I’ve matched them up just now and they are pretty much bang on so there is nothing much
to worry about there. So what we want to have a look at mainly from a plumbing perspective
is obviously this bit here. Now there is a small
problem that we’ve got with this instal here
and I’m gonna rectify it by putting our pressure reducing valve, actually on the mains incoming, okay? Because we’ve got mixer taps and we’ve got a mixer tap up here and
a mixer tap next door. What we want is the cold and
hot to be exactly balanced because a mixer tap doesn’t want a high pressure of cold going on to a slightly lower pressure of hot because it’s being reduced by this valve, but what we’re going to
do in this instal here is we’re gonna put our
pressure reducing valve right by our mains incoming in, so then everything on this whole system is then reduced to 3 Bar. So I’m just going to
cut that in quickly now. Right then guys so there is our pressure release valve on there. So our cold water flow
is going through here off to everything, there
is nothing on this side apart form a drain-off on the valve on our main stop off valve and on this side is our whole system, so that’s where we go in now. Now usually I wouldn’t
recommend you do this, guys. Always follow the
instructions down to the T, but I know that this is gonna be fine, we’re not gonna have any problems, and it will also get signed
off by Building Control. So, let’s get on. So, this is basically a non-return valve we’ve done videos on these in the past they stop water going back
down the cold water main. So, that’s gonna go
here just here, like so. Then, after that we have our little expansion vessel as well, so we’re gonna have to figure out where we’re gonna fit that too. After that, all we have
to think about doing is running our high pressure relief pipe. Before we fitted this kitchen, I’ve brought a little bit of 22 mil out under the kick board. So, what I’m hoping to do is when I hang this beast in here, like so, tuck it to the back a bit
and then run down here, put my tonne dish nice and high there and then run this through the floor, link up the 22 mil that
I’ve got going outside and then that should be fine. That’s perfectly compliant, there is nothing wrong with that. The reason I haven’t gone for a Mac valve is because the waste here, this is the lowest point
of the waist at this end and that’s really to high
for us to get our 30 mil drop before our first bend on the PRV. Yes, guys. So, anyway, enough of my jibber-jabber. What I’m gonna do now is I am just gonna hang this beast up, that’s my fist bit, and then I’ll know exactly
what I’m working to, where I can fit stuff, this kinda defines where everything goes in it, really. So, let’s get on with that now. (heavy rock music) ♪ Let’s get goin’ guys, yeah ♪ ♪ I usually mark my pipe runs first ♪ ♪ And then I put my clips in straight ♪ ♪ The result is that my
pipes are straight, yeah ♪ So, there we have right now, we’ve got the shut off valve, a non-return valve here. Then we’ve got out T going down to our little expansion vessel. Now, we’ve got to raise all that up and bring that all together up here. ♪ Oh my God, yeah ♪ ♪ We getting ready for some plumbing, oh ♪ ♪ Oh my God, we gonna be
doin’ some solderin’ ♪ ♪ I never knew that soldering
could be this much fun ♪ ♪ I never knew that solderin’
could be so relaxin’ ♪ ♪ I never knew that solderin’
could be this much fun ♪ ♪ I never knew that solderin’
could be so relaxin’ ♪ Alright then guys, we’ve
got everything done, we’ve got all our water in, before I do my high pressure relief
I just want to test that all my connections are okay. It’s just what I like to do now. So we’ve got the water
back on as you hear, hopefully you can hear that. As you can see, I’ve
Brassoed all my pipes, made them all look nice, I did that before I actually
put the whole tank in. So, now that we’ve got
our cold fully on here, we’ve checked for leaks everywhere, everything is okay, I can
open up my hot just here, just gonna half-cock that a little bit. Yeah, look, there we go, we’ve got water coming out the hot side now. Also, if I just, phew,
if I just hop up here. Kingspan, see someone installed here. There we go, everything’s on there. So, now we’ve got hot
purging through here as well. Lovely. Really, really pleased with
this, it’s going really well. I tell you what though,
the space to film in, look at it, look at that
space, phew, it’s tight. So yeah, we’re just
going to get everything sort of switched off now really, and make sure everything is okay, then get the sparky over
here, get it all wired up, and then I can show you just how hot one of these beasts can go. (gentle pop music) So, then guys, another day. The sparky’s been in and
done all the wiring stuff so you’ve got a nice little plug up there with a fuse there, ready to go. It’s not quite tight but that’s the place he said it
should be, so there we go. What I’m gonna do now is just get my high pressure relief sorted out. We’ve still got the water off from my pressure test yesterday
so that’s all okay. So, I’m just going to pop this off, we’re gonna link up to our
pipe that’s underneath here that runs just outside
and pops through the wall, and then just terminates normally like a standard high pressure relief. So, let’s get the drill and go. (soft jazz music) (mumbles) now, so I’ve just got to put a shallow little set on this. Just gonna do this set by eye, it doesn’t really need a lot, it looks like it only needs
about, not even 10 mil. So, I’ve now popped the
water back on as well, we’ve got our connection done outside underneath our kit board
so that’s all done. I got one there. I have like, a shallow set
mark cut on my benders. I’ve gotta say guys, I’m so
glad I’ve got the Hilmors back. That’s how it is, I just know Hilmors. They’re what I’ve used
since I was an apprentice. He says he knows Hilmors, I’ve
probably got this set wrong. So, we’re just gonna get these in now. And now I’m just gonna
test everything for leaks, then we’re gonna test operation. (soft jazz music) Just gonna give that a light nip up. There we go. Next thing I usually do, when
you’ve got your water on, just test your tonne dish,
make sure it’s all okay. And obviously test your pipe work that you’ve got running outside. So, just run a bit in there,
that’s absolutely fine. Yeah, that’s running
away perfect so I’m just gonna go check underneath
and make sure its alright. (soft jazz music) Right then, guys. So we’ve tested that there’s no leaks, we’ve really clipped down our
little expansion vessel there. We’ve clipped nicely all
our high pressure relief, and we’ve clipped and made
good all our pipe work in the back and Brassoed it all up. Now is the time to turn on and make sure that our electrician’s done the right job. So, let’s do that. So, there’s our switch. Boom, we should be on. We should see a little light down here. Got a little light? Yup, we’re on, and we should hear a click. Cool, so there we are,
I’m just gonna set that sort of in the middle there for now, and let’s get scanning and seeing how quick these beast actually heat up. Okay, we’re all on there. (mellow techno music) We’re gonna open up this hot
tap, there we go, it’s on. We should see that top
part getting hotter. Yeah, look at that, you
can see that now can’t you? This is literally just an excuse to use this Flir camera
because it is so cool. All the way up there, how wicked is that. That is so cool. Nearly 40 degrees coming
out, 35 degrees there. And what we got coming in, 21. That’s only after a couple of minutes. In a few more minutes time that should be hot enough for me to
wash up the cups here. Alright then guys, we’ve had it on for a few minutes now, so let’s turn the beast on, we should see, oh yeah we’ve got the
steam, we’ve got the steam. Hell yeah. Right so, my next job now, is to quickly clear out
all the plates and cups, then I’ve got to put the doors back on and then that’s pretty much it. I’m gonna probably get
this set to temperature, ’cause at the moment, that’s pretty warm. So, I’m going to get that set so we put a little stick on it, make sure it’s around 55 degrees that’s kinda what I aim at
for hot water temperatures. Thanks ever so much for

  1. Hi guys I hope you enjoyed this weeks video! Sorry about the songs but I couldn't help myself! If you want to follow my Instagram click here y'all: http://www.plumberparts.co.uk/social.php?social=Instagram It's a place where I share loads of photos that you guys send in, plus it's always a good laugh on the stories section, plus the jobs I do during the week.

  2. Top job super shiny pipes! Have you ever had a leak with loctite? Just started to use it and I’m not 💯 confidante with it.

  3. Nice install…Ive seen these used for a shower rather than a normal electric shower option on my travels…and they work very well when mounted as high as you can..

  4. Why when I run any water in my house it makes a loud knocking noise is it just I need to turn my water off and run all the taps ?

  5. Very neat, good job bro, i would of not placed the spur so near the edge of the sink, just in case of damp and leaks from the sink

  6. 30 mm or 300 mm drop lol
    Love the vids.
    Big fan I’ve just had an op and your keeping me going.
    Hold tight

  7. Shinyyyy copper ^_^
    I like the look of one of these; they'd be very handy when the boiler packs in in the winter and you get sick of boiling kettles 😛

  8. Been watching your videos for years now! Seriously learnt so much from you! Keep the videos coming! The more the better! Hold tight! Oh and where’s The Big G?

  9. Nice work..
    I noticed your hot and cold pipe touching just before the isolations..
    I thought that’s not rite..
    Let me know if I’m wrong..
    Love the vids though..

  10. That kingspan pack seemed like the business. I got an Ariston one from plumb centre lately and had to buy everything eles as an extra.

  11. James , quick question after looking at you schematic. The Pressure reducing valve is before the none return valve. When I fitted my water softener I fitted the PRV after the non return . Does this matter ????

  12. Great vid and useful comments. One question re expansion vessel bracket/pipe clip – how did you do it? A long screw through the pipe clip and pipe piece into cabinet bottom?

  13. I've got to say James your editing and video skills have come on leaps and bounds over the past 3 years.

    Going the effort to create your own vocals with humour is leaps and bounds above what other plumbing related channels worldwide efforts.

    You are an example for putting effort into your channel.

    Absolutely solid filming, editing and content ideas here.

    Thumbs up, oh and also THOSE FULL BORE LEVER HANDLE VALVES —— LOVESSSS

  14. A plumber told me before that an expansion vessel could only be mounted with the connection on the bottom i told him it didn’t matter as long you can get to the air cap. What your view on this? I’ve seen them mounted up, down and side ways like in this video.

  15. The IR camera won't work on metallic surfaces as you demonstrated – the emissivity constant on the FLIR is incorrect for that as demonstrated by the 'cold' water inlet temperature.

  16. Hi mate love the channel. Could you do a video on fitting quadrant shower enclosure on your own. It's a nightmare

  17. James' Heatrae Sadia now won’t warrantee the expansion vessel if it’s fitted horizontally. They insist on the vessel being fitted vertically. They said it causes issues with the water draining out. Hope that helps… love the video’s.
    Regards
    Carl
    Waterlines.

  18. Links to the tools I USE EVERYDAY in the description above! Still uploading helpful video today! Plus Follow my Vlog, TimesWithJames http://www.youtube.com/c/timeswithjames

  19. Easy, straight forward installation.>>>ur2.pl/1103 We installed this in our 2 bedroom 1 bath cottage in Northern WI and I set this to 120. Water is HOT! Compact and takes up almost no space at all and it doesn't make a single sound. I thought there would be a slight "hum" but you don't even know it's there

  20. Does this kind of HW storage unit need to be near a waste/drain away at all? I just wanna fit one higher up out the way, for some pressure and equidistance between taps?

  21. I also use this
    product, which is similar to this one, and it is economical. You can click to
    view it at the following URL.

  22. Efficient and
    energy-saving to meet daily needs, take the website

  23. Sorry, what's a MAC valve? IS that an abbreviation?
    I assume it's something that lets the pressure relief valve discharge into the sink waste?

  24. Where can i buy this kit from looking around online there is nothing like this all in one kit your demoing? i checked screwfix etc

  25. Why the fuck do you wankers always double the fucking volume for the music during transitions? Do you enjoy people turning their volume down and then back up again for the voice??
