Please help me mate why is my hot water coming on with my heating
I have an old type copper boiler with no drain off at the bottom so once I ha e got to the part of draining off the hot taps once the water has stopped running I undo the top exit pipe the water is just at the top of the tank, using a piece of hose I siphon off a foot or so of water, in my case into the bath, the water level should be below the thread of the immersion heater, create h the outlet pipe then remove heater , from then on in it is must replace heater and connect wiring
If you'd told me a few years ago I'd be attempting an immersion heater replacement myself without calling in a plumber, I'd have laughed in your face. But I've just done it, and I'm not gonna lie, I feel like a boss! 👍
I've been studying plumbing for 2 years in college, and sometimes I learn more in your videos then I did at college.
SNAP
Especially during the past 6 months due to lockdowns
Because plumber parts is about real world plumbing. Can't beat it!
DO NOT FILE THE TOP as the video displays !! The video method clearly demonstrates that filings & washer debris etc can get into the cylinder & therefore hot water pipework. Modern taps & showers often have inline gauze filters & therefore this debris will unnecessary clog such filters causing additional issues/potential tap flow rate snags. If no such concerning filters are present the said debris therefore risks scratching tap seatings or valve discs that over time can develop into dripping taps. This ought to be basic information to any plumber. Use a cloth to prevent debris entering the cylinder whilst cleaning the flat top collar area with some emery paper, file or chisel for stubborn pieces.
I thought the same as I watched, good video but that was a clear mistake.
Big help, thank you
Just done this job for my first time all i can say is a big thank you Jimmy
Watched this at the weekend and helped me change my immersion with zero stress. Top work, great vid!
Thank you very much for this video. It gave me the courage to replace the immersion heater which had never worked at my girl friend's house. I bought the huge ring spanner and I already had the box spanner. It wouldn't shift, so I gave each of the eight flats a good tap with a hammer and hey presto, it moved.The drain cock was stuck, so I opted to open the joint at the outlet pipe at the top of the tank and siphon off a bucket of water before removing the old heater which was physically broken. We have hard aggressive water here and a copper heater had been fitted (not good enough!). I fitted a new Titanium one which I hope will last a long time. Thanks again.
Excellent video. I used this to great effect today. New immersion installed and working perfectly! Thanks James! Hold tight!
Great, practical, hands-on advice. Doesn’t come better than this…👍
What a great video mate well done!!! You've given me the confidence to tackle one that's been in since 1975!!! Will watch this carefully a few more times, but got the stiltson wrench ready to go. 👍
Great video..used this and replaced our element today..it had started to trip the electric..quick trip to screwfix and picked up replacement 27" Tesla for hard/soft water and copper/SS tank..24.99..subbed
Thank you so much for this tutorial. Just installed a new element with the help of your video and everything is working perfect. Much obliged, good sir :)
Brilliant instructions. ...
Spot on...
I used Fernox sealer......no leaks!!
Not sure why it was necessary to drain down the tank....the hot taps alone did a great job for me..
Got the special tool on Amazon...
Photographed the old wiring !
Thanks so much.....
Start with a full tank of hot water (This will help), loosen the element, use a blow torch to heat the inner area of the element boss thread, don't heat the outer edge as you are heating the soldered in boss thread mount and it could rip the boss mount from the tank, tap round the hex boss on the element to shock it and the element should then turn with a bit of elbow grease without ripping the boss mount off or distorting it.
No need to drain the whole tank with a top feed element, just get some towels and soak it up as there won't be much water coming out the boss mount.
Wire wool or scotch cloth the heater boss mount, also clean the mating surface of the element, use boss white or true blue on the element boss thread and face, put sealing washer on element boss thread, apply boss white or true blue to the clean side of the sealing washer, screw it in nice and tight, no leaks guaranteed.
Also check what size of top entry element the tank will support, I have just replaced our 27 inch element with a 36 inch element that reaches to 2 inches from the bottom of the tank.
The longer the element the less strain on it to heat the hole tank.
Brilliant, clear explanation - thanks very much.
Thanks for posting this, VERY helpful.
Jimmy! This is a fantastic video!!! Very easy to follow and really well thought out. I followed your guidance to the tee and I am certainly not an electrician or plumber. I got a new element part and giant nut tool to make sure I could do the job properly. You're right; cracking the giant nut was the toughest part but everything else went pretty smoothly, so I just wanted to say a massive thank you for all of your help!
A really well made and informative video. Thank you.
Here we go, let’s go and knacker up my immersion heater! Thanks for this mate, super helpful. I’ve subscribed 👍🏻
I like your style, no BS, straight to point and well explained to complete newbie!

Perfect mate. Great tip on cleaning the sealing area with a file.
Like your style always good reliable advice with a great attitude. Keep up the great holiday videos.
Don't usually tackle plumbing jobs (despite being an experienced diyer) but followed your instructions and "can you believe it" all went well. Top draw that man....
No worries!
Great video Jimmy! Just replaced an old immersion heater after watching your tips - yes it was tough but went well anyway. Thanks for the help and the entertainment!
+thomas chatterton No worries!

Great Video, Well documented. I noticed the connecting wires looked a lot better after element replacement. had they been cut back & re-dressed, as that was not shown in the video. The wires on my tank looked in bad condition, hence I had to cut off the bad section & re-strip.
Hi
Old school advice if you turn the immersion heater anti clockwise when fitting slowly you will here a slight click that means the threads are correctly engaged ,then tighten slowly.. try it.
Dude that's the way I've always done it!!! Forgot to say!!! Cheers, PP!
Good tip. applies to most threaded items too. :)
Thanks so much for this video - brilliant! My Boiler broke yesterday so no CH or HW and then I discovered that my Immersion Heater wasn't working either. So plumber is coming for the boiler tomorrow but thanks to your video I was able to successfully change and repair the IH so at least we have HW. Thanks again 😊
Nice one James, much appreciated.
thank you, in a older house and this may be useful at some stage. thank you !
Great video. Many thanks. From Ireland
A great step by step informative video. 👍
James, thank you for uploading this video. It was exactly what I needed as a check to ensure that I didn't make any schoolboy errors. Cheers!
Tank plugs are a time and life saver sometimes. Get that gate valve swapped for a lever for your mate. Nice one James.
You are great I’ve done that much stuff after watching you 😀
Thanks for this great video!!
Another great video! Keep it up 👍 and hold tight
thanks for this vid. just what i needed
I watched your video last week. Bought new immersion heater, spanner and jointing compound online. This morning, I followed your instructions and managed to replace my immersion heater in under an hour. Thanks for the step-by-step instructions. Very clear and easy to follow. Wouldn't have known what to do or dared to try it without your video.
Yes, I did the same. Got the large Ring type spanner from Screwfix £9.99 it did leak a little so I used some sealer then ok. Next time I would check for leaks before wiring up!
Thanks. Very helpful.
Very interesting and informative. Thanks
Great, practical advice, young man.
I was hoping the extraction was gonna give you more problems - mine probably will - just to see how you managed it...👍
Thanks for the video James. Great explanation of what's needed. Can I just add though , in the video at 1.45, if the immersion is actually on a plug top then the BS7671:2018 On site Guide to the 18th Edition of the Wiring Regulations recommends at H5 that water heaters fitted to tanks exceeding 15 litres (as that appears to be) should be on their own circuit and the immersion heater itself should be supplied via a switched cord-outlet connection unit complying with BS1363-4. I couldn't quite make out what was going on with the switched FCU next to the single socket but with the flex running under the back of the front plate it could probably do with some upgrading!!
You’re nuts mate, love it never change, thanks for the video
Great video, thank you.
Can’t believe I’ve subscribed to a plumbers channel. I need to go and buy a broom and dust pan now. 😂😂😂😂 honestly though a great video 👍
I had a small leak. I used some sealant ok now. Next time I would check before wiring up as you did and have that cup of tea. Thanks for posting a great helpful video.
really helpful, thank you
Great informative vid thanks!
watching your video i feel; confident to change the immersion on my boiler myself, 1st time ever ! i hope i dont screw up
Excellent and informative video :)
As usual, plumbtastic....Hold tight.
VERY EDUCATIONAL INDEED. THANK YOU.
Great video thanks👌
spot on - nice vid explaining what needs to be done - now i ll need a plumber in Newbury lol
Great help thanks
good video mate cheers
Boy did that one yesterday leak. Finally a second washer and a few rounds of PTFE tape worked. If nothing else works to free it, an extension tube on my ring spanner tool always works but its a risk, I know. A wipe of soap on the immersion threads, makes the next time easier.
I Love Jimmys videos and i dont even do any plumbing. Geeza and im learning alot .Reeeessssspect
Thanks for you help.
Cool Plumber, got his shades to hand at all times!!

Thanks very much
Thank you
Excellent
Love your videos PP I watched every single one of them, would love to see more videos of you in the van though!
Saved my life haha cheers pal
Thanks
All very good in theory. I just had one that resisted all efforts to loosen.
Cracking it when full, heating the flange with a blow torch, you name it, every trick in the book. Ultimately a bare hacksaw blade to cut through the fibre washer and then a bit of a 'love tap' with a heavyweight spanner.
Don't know what's in the water but a lot of green copper oxide 'welding' the washer better than epoxy!
hello I am john , I am at motherwell new college doing NQ PLUMBING love it
I'm impressed. The gate valves actually turned and didn't come off in your hand. Must be quality ones, like Pegler. If only they were all like that!
Thanks and keep up the hard work. Hold tight!
I was told that you should set the temperature at 65 c to kill any legionella .
@@JohnSmith-vy4lh the element should be set to 60*c kills legionella,
Great vid. Is it worth checking the thermostat first? Much cheaper and easier to replace if just that's the failure.
Great video, just started looking at replacing a leaking one. The rust was shocking, looks like it had a new thermostat that wasn't sealed properly. Very dangerous as the leak was right at the electrical connections.
Great video mate.......what do u do if there's no drain point on ur cylinder ??
Excellent as always but 50 degrees is a bit low, 65 would be better to ensure you don’t get legionella infection problems.
There is a whole industry built up around Legionella but what is the actual risk? There are 200-250 cases in the UK and half of those are contracted abroad. So the remaining how many are in domestic environments? Regularly used taps and showers are by definition the least likely to grow legionella and for most domestic environments (which the bulk of the population live in) the taps and showers are regularly used - so very low risk. The higher risk sources are commercial and public buildings, air conditioners, humidifiers and kit like hot tubs.
Note I am not saying there is no legionella risk just that it is very low in the average domestic property but the hype around it is overblown or disproportionate.
As far as I know legionella grows in the blanked off part of a T section where the water does not circulate. This would be the section of stagnent pipe with the drain tap on the end. Maybe release some water the length of the pipe. Could be about a pints worth once a year?
Love this, I heard you are supposed to flush your tank to clear debris from the bottom, how do you do that?
Hi Jimmy.
Great tutorial, very helpful.
Quick question, my new gasket is different on either side, one side nice and smooth the other shining with manufactures logo on it, which side face up.
Thank you. Mark
Great vid...but would have loved to see the taping and jointing compound applied.
How would you drain an old horizontal hot water cylinder? The immersion needs replacing but its located at the bottom of the tank so need to drain the whole thing...Holding tight! Cheers
Alright, let's do it tomorrow.
Fair play I watched this and thought feck that I'm just gonna pay a plumber to it lol.
Another great informative video. When you opened the drain valve at bottom, did you just need to let a few litres of water out or did you drain most or all tank. Thanks
James, are you able to advise me as to why when the hot water thermostat goes on, after about 30mins or so we get a loud rumbling noise coming from the hot water cylinder (where it sounds like its gonna explode) then we get water gushing out from the overflow pipe outside and the boiler trips out and turns off?
Hi, I want to run it on timer and bought 13a timer and socket. Please confirm if 13A is enough to run combi on timer?
what happens to all of the residue of that stuff you filed off the immersion heater entry? it all fell inside, what's a good way of clearing the cylinder out?
Excellent. Got 4 valves in airing cupboard... two red, two black. What are they likely to be?
Brilliant video. Do you have a video on possible reasons why the hot water pressure, (to all taps), is rubbish (making bath mixer/shower taps unusable)? I rent and my landlord won’t do anything. It’s gutting, as I paid a plumber to fit the bath mixer/shower taps.
@plumberparts we had a bungalow oppersite us they where out at the time there immersion heater blew up, what would have caused that. Part of the roof came off also
You should be in showbiz bruv
Ive tried to get a couple of immersions out the side of a 210 litre direct Fortic and the boss started to bend in…that was where i stopped before the cylinder got torn. Have you got any tips? Im not keen on using a blow lamp in case it sets fire to the foam insulation but maybe a hot air gun and some taps with a hammer? I think its got thread sealant on it too, and its been there since 1997.
oh my gwaaad
Hi, did you just install a 15amp immersion with a 13amp plug and socket. What is the supply rated at?
Genial na minha casa estamos com o mesmo problema agua nao esquenta .nao consigo soltar o heater element.
Might be a daft question but if the water is cold and electric isolated why do you need to drain the tank if your working at the top?
If you dont have a blow torch would turning the thermostat all the way up and turning the water on for 15 minutes produce enough heat to lose off the immersion heater if its being stubborn?
Wasthinkin that myself but no probably not 70 degrees is the max on most!
Youneed 100 to melt the sealer on the threads!
If a open the bath taps instead of the drain off tap would that still empty the tank enough to take out the element
Hi, what paste would you recommend? And do you put the paste on both sides of the gasket? You didn't show this in the video!
How long should i hold tight ? , coz some issues might come up in the future ...
The cable supply shows heat damage (at around 3.50 mins in), so would be wise for the cable terminations to be remade, and the heat damaged section replaced. Either cut off the damaged end section of the cable if long enough, or fit a new cable back to 3 pin plug. Easy enough to do if you have the shelving over the immersion removed anyway!
What spec cable please
@@toy838 I would use 2.5mm butyl rubber cable. 1.5 mm at a pinch but it's got to be butyl not pvc as it will melt and disintegrate with the heat.
suddenly its wired up. would be good to see this actually happening, some of us are watching this with very little knowledge, so would be great to see how you have wired up the earth on this? thanks for the video
