We've all missed you Luke, please come back. Your videos are the best.

Hi Buddy! We are waiting for the new contents. Best regards from Hungary. An another Sparky Guy

Very clear to understand, pleased people like yourself take the time and effort to show these little tricks to help others out. Great vid

At a time when we live in a throw-away society, it is nice to see some good old fashioned fault-finding! Excellent explanation as well at a decent pace. Reminds me of my Fire Alarm fault finding to understand what type of fault a circuit has! Thank you and Keep up the good work

Thoroughly enjoyed this tutorial....Especially the 500v DC Insulation ''Live'' test

Luke, this is without doubt one of the best everyday problems electrical videos on the Internet. It's been years since I last saw an immersion heater until a few weeks ago. I must admit I had to dig a little deeper that Monday morning to come out with my hot water tank experience. ( I blame combi boilers ) it's great this is out there for others to understand and learn.

Love the way you've applied Ohms law to rule out faults. Thanks for the video!

We used your videos to troubleshoot the immersion heater. Very useful. Please keep making videos. Thanks

Great Video! - Several times I've been called out to a thermostat stuck in the on position, and as you say, the HW tank just becomes a kettle. I've seen the header tank heat up and because of this and steam up a loft which in the winter months means heavy condensation, mould etc etc. Keep up the good work.

Absolutely cracking video! Especially appreciate the extra effort to add on screen calculations

Thanks. Very informative with a lot of theory with practical information.

Yes, informative vid, I've changed my immersion element a few times, Original one was installed in New cylinder in the 1990s, A standard copper rod, lasted only about 18 months, second copper one about the same, so in the year 2000, fitted a dearer 'Superloy' version & it's still working to this day! I'm in a hard water area too. Good point at the end too, about never bypassing the thermostat, also the immersion cylinder must have an expansion pipe as well, in the event that the contacts weld themselves closed.

I'm surprised at how many copper rods I pull-out. Never stood a chance.

Excellent video, really enjoyed watching it. Keep up the good work mate

Really excellent piece of teaching. Thanks.

To p stuff mate. Can’t wait for a demo of the faulting on them rig-consumer units. Keep do you and yourself proud! 👍🏾👍🏾 Links

Very informative video--- Many thanks.

So a couple things, just found your channel and it's brilliant. Immersion stats yes it's bi-metal dual rods welded at the tip acting as a bi-metal strip. The immersion element itself is the same construction as MICC. The purpose of the thermal cut-out is purely to stop the tank boiling over filling the plastic tank in the roof, melting and scolding someone to death in bed asleep below (the actual cause of the legislation requiring them) - or the pressure relief valve going. Causes of over heat tripping, faulty main stat or scale in the tank, if it's an older tank it's most likely scale especially in hard water areas. A 13 amp switch fuse is adequate for correctly sized for modern "3kw" immersion elements with 1.5 flex from the outlet according to the EU norm. It should be noted however that the UK uses 230/400 volts as the "EU norm" when the average voltage across the country is closer to 245/430 volts. Effectively people are installing immersion supplies to a standard that's been harmonized which is not actually suitable for use.

That was a really good and helpful video. Many thanks.

Excellent video 👍🏻👍🏻

Great video. Just what I needed to fix my immersion. Now I don’t have to wait for water to heat up when the kids had used it all (2 immersion system only).

Quality video. Theres some quality educational content knocking about on youtube recently.

Enjoyed that video mate keep them up 👌🏻 💯

Awesome video 👍

Please come back

Very good stuff mate well explained

Nice Video mate 👍🏻 You along with Artisan..Mr Savery and Tom Nagy are really churning out some good stuff!! Having spent years repairing and replacing these on social housing contracts i have to say i have never been totally happy with the new type thermostats..Lots of times the bi-metallic strip gets stuck in the open position which lead to many an emergency call with no hot water. Great point regarding the D.P switch and 16a mcb. How many do we actually find hanging off a fused spur with the 13a fuse welded into the holder..😩😩 Keep the content coming!! 👍🏻

Where has he gone? I miss his videos!

Great video, surprised nobody came running downstairs with all that beeping thinking smoke alarms going off !

01:40 tip for keeping the leads more organised. . . when packing up the tester 1) plug all 3 of the leads into the socket breakout tester 2) hold them up so they're dangling 3) lower the dangly leads into the bag leaving the 3 pins of the socket tester pointing up Now, next time you go to get the leads pick up the socket tester and there they are all dangly and untangled 🙂

Great video cheers

Where are you? Your vids are some of the best. I hope that you are well.

Nice one mate 👍👌

Very interesting video----I recently cleaned up the earth connection on my immersion which had blackened and it has improved heat output quite a bit. Maybe I have a bit more to do as it is not as hot as it used to be originally.

Thanks 👍

Good and clear. Thanks!

Great video. Cheers mate

Hi Luke, keep up the good work 👍 your videos are extremely helpful. Have you considered doing a testing video with regards to a EICR or minor works? 💡

Great info 👍🏼

Mate hope you are doing well we all miss you 😘❤️

Great video. I like to always mention too customer possibility of tank tearing or boss fracturing when changing immersion. Wonder why I started doing this ? 🤣

That’s good learning a lot

Excellent you are a genius thank you so much

Superb! thanks!

I understood the thermal cutout was there to stop the water boiling if the stat failed, not to protect the element in particular. There were cases of cylinders boiling over and plastic dtorage tanks melting in the loft, sending boiling water into kids bedrooms etc. This is why immersions without a cutout must be replaced wherever they are found.

Great video thankyou ...you tested the element with ohms to get Power...would you also check live to neutral using the 500v from the megger to test that it does go faulty under load.... Geoff

Hello Master we have not seen your videos again hope you doing well.

Hi from Israel waiting to see another video

Top Electrician

well done

Great video m8

Hope your ok just wondering when you'll be putting more videos up

Hey Luke good to see you with nick bundy be good to see you back on you tube

Thanks it’s helpful

Thanks for the video. Very informative. I'm not very experienced yet and so have a question. When you got the shock why didn't your other hand also get one as it was holding the element?

Very clear and precise. Watch a lot of your videos as studying L3 at the moment. Do you come across any 3 phase stuff?

Alright mate hope everything good, haven’t watching any your videos in mouths from the first lockdown

Once had an immersion where the overheat stat failed that was attached to the immersion. It had a short to earth. Cut it out of the circuit and tested the element which was good and not shorted to earth. Replaced single thermostat with new thermostat with overheat stat and problem was solved. Saved draining down the cylinder to replace entire immersion as is was in the side at bottom

Waiting on your next video mate. Hope everything is well?

My 3 kw under sink water heater 15 l should I fit a fused switch or un fused

Hey, great video, would you code a 13amp fuse spur as c3 in a eicr?

Thanks boss

Come back!

Any advice for testing 3 phase immersion heater and is it advisable to remove thermostats when performing insulation resistance test?

Hi Luke. When is ur next video coming out? Why haven't you posted anything lately?

Quick question for you if I may please? I saw one of your other videos (really enjoy your vids by the way) where you said its insulting when people who know the colours of cabe and 2.5 vs 1.5 think they can rewire a house. I get that. So my question; if I needed a rewire, but really had to do some of it myself to make the job more affordable, what aspects would you be happy for the (reasonably competent) homeowner to do? Chasing? fixing back boxes? running cables? Where would you personally draw the line? Cheers.

M8, great vid.

Really good video but it is a few years old and nominal Voltage is 230V in the Uk which would give 11.9 amps and 2830 watts so I can see why they would use the fused connection unit but it is close to nuisance tripping over a long time and I have not worked out how long it would take a 13 amp fuse to overheat. so are you saying it cannot be done safely but in practice off course we know some people will or would you always use a 16 amp breaker to a double pole switch for extra safety? thx

Hi,just wondering when your doing the insulation resistant test and use 500v, how can you still hold the element in your hand.I know the current is very low.Thanks

Great video, however at 18:17 when you say about cooling the thermostat to open the circuit shouldn't you be saying to close the circuit ?

Is it the job for the electrician to change the immersion heater or a plumber? Been away from the trade for years now but during my apprenticeship never changed the heater only the thermostat

Hi, Luke, my heating element reading is 46 not in the 20 range, should I be worried and do I have a problem? Kind regards..Kev..

Where have you gone mate

This is brilliant. Just to point out though, you can't overload a fixed load👍

Fareplay to not cutting the 500 v shock out

How are you bro? miss you :)

Why did you calculate at 240V? I thought everything should be calculated at 230V or am I wrong?

Yea that was good...

Thank you Lee

The formula to get resistance is r = V2 devided by the power

I’m an apprentice I just wanted to ask that when you did the calculations you worked the voltage out at 240 why didn’t you use 230

@MyTrustedElectrician

4 жыл бұрын

2 reasons; • The property that the immersion was taken from had a Voltage of 244V and so this would have given me a more accurate power rating. • 240V would provide me with a value closer to failure. Worst case scenario.

@@Jackdaly2000 You'll find average voltage across the UK is closer to 245 volts (used to be 240/415 volts) 230 is the "harmonized EU norm" voltage as the continent runs on 220 volts. Effectively any calculation you learn in college you should change on site to reflect the actual voltage measured on site at the time. If you measure 240 volts use it otherwise you will find inductive/ resistive loads potentially causing heat damage to the cables and terminations.

You can put them where ever you like as its an existing installation. The height for new builds is 450mm but at the end of the day its your house so put them where you want them.

Why no more new vids m8?

Do not bypass this you will make a kettle lol sometimes the most serious comments are the funniest

Inconel coated elements are the best, not stainless.

Cartridge fuses and circuit breakers are designed to run at their full capacity without any thermal effects, so a 13A BS1362 plug top fuse should and will take 12A forever without heating up. Fused spurs burn out because of poor connections, incorrect size cable and cheap makes, not because they are running 12A through them, backed up by a 13A fuse.
