- How to install a point of use water heater under a sink. If you need hot water in a kitchenette and can't get a hot water supply from the tank, a point of use (or undersink) water heater is a great way to solve the problem. I show you how to install the water, what considerations you should have with the electrical supply, water supply and pressure relief valve discharge, finishing with a lovely song about what we've learnt.

Wow, that's very attentive. I'm from a famous brand of hot water heater manufacturer in China. Welcome to contact me, E-mailexpor@jnod.com.cn.web : www.jnod.com.cn
I love the plumberparts soundtrack! Big ol smiley on my face as you dropped the beats 😃👍
This video is awesome. Very informative and Positively Entertaining...better than ION TV.
Thanks for the video mate this is a good watch
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
Really great detailed video as ever. I fitted a similar one recently and reused the original pressure reducer, pressure vessel and pressure relief valve as they were originally fitted. The hot water deliver with the new heater was really fierce when the hot tap was first turned on and then after about ten seconds ended up as a trickle. A friend who used to be a heating engineer told me to replaced the pressure reducing valve. I took his advice as i’m a qualified plumber with Part P but not hearing quals yet. This solved the pressure surge but now the valve gauge gets up to over 3.5 bars when the taps are off and the relief valve is releasing a trickle of water continuously. My assumption is that the pressure vessel isn’t doing its job and although the relief valve is rated to 6bars it has a relief setting of around 3 bars. Also the original vessel was plumbed in right next to the relief valve and is level with the feed at the top of the heater and is located in line between the regulator valve and the relief valve. You mention a 30mm drop to the pressure vessel. I don’t recall seeing that in the installation instructions and the customer has mislaid them. Do you think my diagnosis that the pressure vessel is faulty could be correct and is the 30mm drop crucial? Thanks and keep up this great channel please. Will find you and post a message on Insta too as you’re an Instagram fan.
This is the cleanest copper pipe install ever
Thanks James, really good installation video.
The polished copper is just SOOO cool! Nothing so visual sparking in a bit of grey twin & earth. Signed, The Sparky
Video ~ 14 minutes: the reality - it took me 1½ days to install one of these and didn't do as good a job as ya man !! But now it's done ... it's great!
You kill it mate you make plumbing fun
Superb video !!!
Love it, great video, love the music you made 😁😁
had me in tears them songs you've made jimmy! hahahaaha hold tight!!
Nice ! Well explained
Thanks
Hi there, great video! I was wondering if you could tell me how to fix a leak on one of these?
top work james loved the video.
Ratch Riat thanks dude!
Top Guy and outstandingly entertaining...
Hi does the explanation vessel need to be a certain position ..
horizontal, vertical, or does the pressure valve needs to on the top ?
Or bottom
Thanks great video
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 :P
Really cool video, thanks.
I notice that some makes of unvented water heaters use dielectric junctions. If the manual doesn't say anything about it, I assume it's OK to use just a brass female iron adaptor.?
great work james
Hi How much run of pipe work do you need before you need to install a expansion vessel?
That little pipe song got you a subscribe hahaha. nice video
Hahaha, those last few minutes :D
nice job!
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?
Hey James, I loved the video and went out and bought a Kingspan Ultra flow 10l, installed exactly the same as yours in the video. Its fantastic, water nice and hot when we need it with plenty of adjustment if we wanted it even hotter, so all good! The missus says to me yesterday that there was "Black bits" in the sink?? she was running hot and cold, anyways after a bit of investigating the black bits are deffo coming from the hot feed, any ideas why that would be? Its only been in for a couple of months and works great, I'm up in the Highlands, just outside of Inverness, on the water main though.
You're a funny guy. Love ya vids mate
Awesome tune!
Valuable video. Can you please tell us how one of these would work in a mobile setup? We are setting up a coffee trailer and for compliance we intend to run a flojet pump to an under sink heater. Using a Y junction, we want to run a line via the heater and up to a flick mixer hot side and the other line up to the cold side of flick mixer. Is this viable with an under sink heater?
Could a slow starting hot pipe be plumbed into the incoming side of a under sink water heater? Thanks
Do you think it is feasible to connect an IHW heater (tankless) into a power shower hot feed? Thus reducing the size of IHW heater needed, eg. instead f say a 11kW you could use a 6kW? I ask as I need a temporary over winter solution while my oil heating system is removed prior to the new install in the spring. Just need to have an operational bathroom and didn't want to install a new electric shower as already have a power shower.
Could you install a pressure reducing valve on both the hot and cold pipes going to the heater to avoid installing it on the pipe that feeds the house. Of course you would have to buy a 2nd one but is it worth it to avoid building regs
Great job!
Nice job James
Tonitoni from France ;)
Interesting, James. Ariston have those horrible dielectric couplers to prevent electrolytic corrosion - often a pain to seal - but Kingspan don't.
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?
rj24115g yep!
Top man 👍 thanks
Hold tight 😂😂 love it
Very nice as ever James
Thanks!
Where do you put the pipe connected to the turn dish? Does it have to go out of the property or into a soil stack ? Or can it be put Into the waste under the sink?
Would that heat the hot water for a whole house, ie baths and sinks?
Hi mate love the channel. Could you do a video on fitting quadrant shower enclosure on your own. It's a nightmare
You absolutely rock
Gangsta Plumbing music, brilliant!
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
😂bro you so hilarious bro😂🙌🇿🇦🔥🔥🔥I can work with you anytime
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.
Nice vid great songs , X factor for you mate
Hi I recently fitted a 50L water heater for a bath and now want to fit a 10L under sink heater in the kitchen. Can I tee into the cold water supply between the relief valve and the 50L heater to supply the 10L or does it need a separate supply with it's own pressure reducing valve, expansion vessel and relief valve? Any advice would be greatly appreciated, thanks.
Does anyone know if you can install a 15litre unvented under sink heater without your g3 unvented cert?
Nice video, shouldnt the expansion vessel be installed vertically to prevent stagnation? 👍
That’s what I said 😂😂👊🏾
Yes also the length of the pipe is too long, should be no more than twice the width of your pipe.. which can be difficult sometimes.
and if we are going down that road an anti legenlla tee and valve should be fitted..
which is a a very rare sight aswell👍🏻😂
great film, is that a 15ltr heater
Great vid, just what I needed...
But honestly, I thought I was watching Bradley Cooper hosting!
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.
Golden loctite rule is to cross the thread over itself. Tends to not work as well on plastic thread, where I'd recommend PTFE.
Hiya Plumber,where's Plumb?Like the vid...a lot ;)
Could this be installed with a combi boiler?
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 ????
No, as long as the NRV is after the tee on the supply to it then it will do it's job
If I fit a electric tank and say my gas boiler is also on would the boiler cancel out the flow of the hot water on the electric boiler and cause the pressure relief to steam out the wall ..as I wanna fit an electric boiler for down stairs shower but .if I have both on at the same time would the boiler cancel the hot pressure in the electric cold flow if I fit a nrv ..its been on my mind for some time 😢
Thank you for the video, do you need to have G3 ticket to do under sink water heater?Thanks
It's unvented so yes. A year late with the answer but I hope it helped
@@djdavidastbury Thank you
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.
Carl Fisher no worries, fortunate it’s a Kingspan....and it states it in the instructions too that it’s fine. Also the horizontal bits isn’t actually a ‘Reg’ but actually under ‘recommendations’ - I checked!
Love the snoop dog bit 😂👍
Great video. Can't you just turn the pressure down outside my water pressure is 6 bar but I have turned it down to 4 bar outside. I was told this by anglian water.
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
Good point...
Wait what's the vessel for on the cold feed?
Videos are class mush
Could you explain as to how come expansion vessels are fitted on the cold side of this type of system? Likewise with the prv 🤔🤣
Hi, Would this be able to feed an upstairs wash basin if it was fitted under the downstairs sink ? I know you might loose some heat but the upstairs basin is only used for hand washing and a shave ans is only a small one bedroom house, cheers tanks
I'm thinking of fitting one in a flat but I want it to feed basin and kitchen sink from where the old cylinder tank was can this be done? I have no gas so the tank is an emersion
@@hopdjandy I have just done this Ariston 15lr heater gravity fed from tank in attic installed instead of old copper immersion tank .Electric connection on to existing immersion switch. Feeds both kitchen sink and bathroom sink .3 kW version no need of any other fittings as expansion pipe allready exists heats up in less than 10 minutes only switch on when needed
The soldering relaxing rap was mint
Nice install apart from the expansion vessel is creating a sump though
Lol love the music!
Why the hell couldnt i get a plumber like you for my installations , a real pro job.
Surely the expansion vessel should be upright and drain point on the base to comply with acop l8 regs
😝😂😂 love the music 😂👍
What would I do on a Saturday morning lie in without your videos?
Watch Takeshi's Castle!
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?
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..
I'm looking for a video on how to flush out sediment for this type of heater.
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.
Just down to manufactures instructions
Expansion should be vertical
My redring water only has Luke warm water coming out of the tap ? what is the problem
What is the difference between single point and multi point water heater?
How long do they tank to heat up
You made that 100 times harder than it needed to be.
How many taps can you run from 1 ,
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..
Blimey! Never heard of that before!
plumberparts ...very common in India..
OHHHH RIGHTTT!

why is the hot water pipe uninsulated? to heat the under sink cabinet?
I notice that the expansion vessel is installed horizontally, is this acceptable?
Yep totally fine bro!
Great videos. More importantly, what coffee machine is that ;)
De Longhi one....can't remember which!
where can I buy the working table you are using there ?
On our Amazon store: www.Amazon.co.uk/shop/plumberparts
@@plumberparts Ty x
Not sure if it was the sparky but that fused spur should not be touching sink.
Good video. How much would you charge for an installation like this?
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 ?
Shock arrestor!?!?!?
plumberparts I don’t know anything about it because my hose for my washing machine pipe burst but then we turned the water off then it stopped and we didn’t turn it on till we got a new hose witch we did but I don’t know what to do
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
Ahhh get well soon bro!
can i put an oversink water heater under the sink upside down
Can you help got a problem with mine only Luke warm water?
Pipes are hot water coming out of tap Luke warm?
Point of use
Lol you spend more time doing video editing surely lol but thanks, awesome vid
