One of the best videos on flues. Thanks alot Derek.

Another excellent and informative video, no matter how much you think you know, always watch. There is always something you don’t. 👍👍👍🇬🇧

Absolutely brilliant video. Well explained. Thank you very much Derek 👍😀

Another excellent video from yourself Derek, some rough flues connected to the boilers, shocking 😭😭. Its a very good video for us trainees with excellent information. 👍👍😀

Your videos really bring clarity, can only imagine the work you put in to ensure everything is covered. But big thanks

Big man thanks Very cool and comfortable version of ways to share information with multi family of gas industry

Great video as always, thank you for all your efforts in filming this video👍👍👍

Legend! Been waiting on videos on flues and here it is. Great work.

Jon-Paul Ward. Great video Derek! Some shocking flue installations on there. It’s harder to find a selection of different sized bricks to sit the flue on than it is to install the proprietary brackets! What are people thinking?!🙈

Another quality vid, getting better everytime 👌🏽👌🏽🔥

First rate video thanks very informative and good demonstration's showing bad practice and how it should be correctly done. Thanks.

very useful video with clear examples and explanations.

Another cracking video pal. Very very informative 👍

What a great informative video, I will now look for poor fitting flues whe I am out walking. To my mind they should all be inspected and signed off by regulations.

Great video I was making notes in our training manual when watching the video many thanks derek

Top video always clear and easy to watch 👍

Another good tutorial video from mr derek thank you

These are really useful. Many thanks.

Very useful video, its help a lot , thank you Derek Mohamed Hassan

Your the man keep them coming

Excellent, Humorous, Entertaining

Great video. Great Chanel keep waffling Del 👍👌

Very insightful, thanks

Excellent video Thanks

Fantastic video!

Very good video and information's thank you

Thank you for this video. I have had a problem with my Worcester flue leaking into the boiler housing every time it rains and your point here about taping telescopic flues may be the problem.

Brilliant video 👍

Spot on mate 👌

You are the best 🌹🌹🌹👍👍👍

Top quality 😊👍

Great video pal 👍

10 out of 10 👌🏻

Such clear talk & beautiful explanations. I love this channel 📺 ♥️ 😊😁🧰🔧👍🏾

Thank you

Top notch..👍👍...

I'm Not a gas boiler engineer but I'm a Aerospace Defence Hardware verification qualification test engineer, it's always good to know what's right ✅ in the Gas trade & what's wrong an good indication when looking say for a new home 🏡 The only thing I've changed is a water flow switch for a combination boiler of my own, & thermocouple for an old Central Heating & Hot Water boiler 30 years ago, in the end on that boiler it was found that water was coming from the old dicast heat exchanger onto the pilot light, then a Gas engineer was called out to give the old cast iron boiler a good service 👍, They don't make them like that anymore 😅, before that was installed 40 years ago we had the very old cast iron radiators, those were I'm sure recycled by the installer, those would be well sort after including the very wide cast piping that was taken out, Interesting to look at all the systems, I still really like the Viessmann 200W 13 years old still going very well 👍 I see installation errors using 15mm gas pipe but its not far from the Gas meter, & I was informed by Viessmann I would be better to have 22 to 28mm on flow return except near the radiators, they used 22mm to a block then microbore 10mm plastic to radiators, I'm picking up all the best information for the next installation in a new home 🏡 later on

Great video! 👍🏻Dave T.

Derek great video very informative can I ask the section with the flue too near the door opening can this be made vertical and taken 300mm away vertically and be accepted looking to get my boiler moved with extension being built and best place is next to a door but it would be 200mm away horizontally. Thanks keep up the good work 👍🏻👍🏻

Great vid Derek just watched. Aaron trainee

Ideal boilers book shows a fall back to boiler even a standard length flue

Surprised at how much there is to know about these type of flues. A very informative and interesting video. When checking if there is more than 10ppm CO coming back into the room, do you stand at the door with the analyser probe *OR* is there a certain distance from the door you would stand with the probe? Hope this question makes sense. Thanks Derek 👍🏻 Asian Jon. Training.

👍 Sue Warrington

Very informative. How would you get around with building a pergola (with a roof)on top of the exhaust? It will be a 2.5meters length. The gas exhaust is in the middle:(

I wish i could post a pic on here to ask my question ... ive just noticed my flue on my wall sticks out a good 30 cm out and has huge space around the cirlce that was cut out for it and not sealed in ... which i think it should be ?

👍👍

You said cant use the a flue extender kit to go through a conservatory if the exhaust and inlet are in different places. but can i run both up through the conservator roof on a 90 up then a 90 to level it above the roof so that the inlet and exhaust are both extended to the same place? (using manufacturer lengths and distances etc) Cheers

👍🏾

I've learned more from you Derek than I did at my covid affected course last year!! :) Good lad PS any chance ya could do a air/gas ratio adjustment video with faults, analyser readings, correct tools and process please? Would really help, ta :)

Can you do a video of poor installs of vertical flues please. And correct way to instal. I’ve seen so many with no clips. Screws and really poor designs thanks

at 06:36 the flue is less than 300mm from a window. But that window looks like it is boarded up & so is not an opening window. Does the 300mm have to be applied if the widow is non opening - either boarded up or simply a non opening design?

How long does it take to fit a gas boiler flue which needs to go through to the outside wall and remove old one

great vids We undertake several extensions where the boiler flue needs to be extended. The existing pipe will be returned up the wall and out through the roof. Any chance of a vid on this installation because it must be more and more common

Learnt a lot in such a short space. I will say, you do come across as a know it all. I know there are some rough engineers out there but sending content out slating lad's, when the majority (In my opinion) care about there jobs, end result and their customers, is a bit counter productive. Should be helping each other, not slaying each other. There ain't many out there atm and less good ones, so hopefully your next video is less cocky and more helpful. All being said great content 👍

On my Worcester 25i combi boiler My inlet sticks out about 10 inches, the outlet (centre pipe) sticks out about 1.5ft, it's all plastic and I get rain leaking in whenever it rains, how could this be fixed, I wish I still lived in Droylsden I'd be calling you in

If a flue goes straight up through a roof space, say a porch roof would this also need clips To hold it in place ?

Thanks for tge informative video Derek. I have a ideal he18 bolier. On very windy/wet days I get water being driven in through the flue. Is there a guard /cover or anything that can be used to prevent this?

All these rules are useless unless enforced. I've complained to Gas Safe in the past, and they've basically fobbed me off!

Hiya. Can you help please, when windy outside the boiler makes a rumbling noise and my sure it’s when the wind blows over the flue outlet. Can I attach something like a 45 degree bend on the end or is there something else you can use. Thanks

Hi could you tell what test is before connecting open flue appliance to flue. Please

Hi Derek, I have a question on flue gaurds if a flue is under the 2 metres and hasn't got a gaurd is it AR?

👍🤓👍

My neighbors gas flue was emitting flames so I rushed round and found she wasn’t in I turned her gas of at meter, to be safe haven’t heard if it was a blockage or what could be the consequences of this?

If the white section of the flue is plastic and UV resistant, other than being not as visually appealing are there any other risks if there is a small section showing?

Quick question what about when the flue is up high and has to go past the eves. Which is does have to. , The white part will be sticking out to far. What’s your take on that. Because mi say it must go past

Plumber installed a gas pipe 100 mm next to the flue Is this OK, thanks

Good stuff 👍

16.44 600mm if it is adjacent to an opening, from the side!

19:50 That looks like something you would see in the r/crappydesign subreddit.

The 10ppm reading that changes things from AR to ID sounds strange, wouldn't it change from day to day depending on weather conditions? Also is that test done with the door closed or open? Thanks

is it normal for water to drip/spit out the flue when the boiler is active? If not does it need immediate attention?

My boiler shows error during rain...is there any way to manage?

If a boiler is already installed in compliance with then current manufacturers instructions (2020), then later the manufacturers instructions change (2023), does the installation become wrong? Is this reportable? The Worcester Bosch 2000 installation instructions changed do we need to report this as at risk for not being as per MI's?

CH👍

9:52 ideal flue 10:44 that is a anothor vokera 12:52 the botton one is a baxi 15:49 that is a balcony but still an ideal 16:33 that's a vokera 19:08 they are both baxis

Great training video 👌 I know your focusing on flues, however 13. 35 mins in, the discharge pipe terminates above the flue below which will cause water ingress into the below flue ID flag straight away 🤔 In the years I've been doing this job 28yrs on fact you have to have eyes of a sh_t house rat, To all the begginers in this job " Never get complacent"!!! 28 years in folks and I never think I'm dogs doo daa. REMEMBER the golden rule LAST COMPETENT PERSON 🤔

Water getting into the top of my boiler blowing up 2 fans. any idea?

Do Worcester allow you to show white outside?

Thought if I'd and customer not allowing to cap off you wher to phone transporter to come and disconnect

chris taylor

My flue making a whistling noise it’s driving me bonkers 😩

Marc crowther

Can mice enter the house by flues?

Is there any time that this man is going to say how to do it, instead of showing photo after photo on how not to do it Totally dreadful video
