A cake slice also works to clean between the heat transfer coils. I personally use a garden sprayer to clean the hex's. Also if you're replace the burner gasket. It's a good idea to use this cardboard packaging to protect the rear insulation panel. Excellent tutorial Derek 👍
I tried one of those brushes - unfortunately it's impregnated with Silicon Carbide grit. Luckily I noticed it was scratching the stainless steel and promptly stopped using it. Interestingly Viessmann sell a metal brush to clean in between the coils only. I now have this tool.
Good video for new recruits and to all those who only probe. If a Manufacturer is asking you to only probe then is that correct? You still have to take the burner out to check the flame and ignition probe and check the condition of insulation so why not clean the H.E.
Hi Derek, great video do you have a link to the brush and drill extension,or advice on where to buy them. I have searched on Google but unfortunatlt not found any
If the heat insulation panel is cracked or damaged is it an absolute nightmare to replace ie full heat exchanger out and everything else infront of it? Or does it just pop straight out and a new one in.
Please don’t use drill attached brushes to clean the stainless steel heat exchanger, it really gets to me and I cannot stand it, I work for a manufacturer and it says nothing about that in the MI’s so I have no idea where people are getting this from. Infact rather than cleaning the hex you are actually destroying it by removing the heat treated coating which contains chronium which is the element that stops the ferrous iron rusting through. When people do this it accelerates intergranular corrosion and the ferrous iron balls build up and the outside of the heat exchanger which have leach out of the stainless steel. Which I turn destroys the hex and turns the trap orange. Sorry about the rant.
Yep , Its no no on Viessmann boilers to use brushes at all . Vacuuming and clearing the path between the coils makes sense only with the correct tool , why do you want a shiny exchanger it is not improving performance.
Viessmann 100-W " Please note Scratches to the surfaces of the heat exchanger that come into contact with hot gas can result in corrosion damage. Brushing can cause deposits to become lodged in the gaps between the coils. Never use brushes to clean the heating surfaces. " &" Note Discolouration on the heat exchanger surface is a normal sign of use. It has no bearing on the function and service life of the heat exchanger. The use of chemical cleaning agents is not required. "
You did a fantastic job considering you only spent a couple of minutes. Are most heat exchangers stainless steel? Also, I guess you’d refer to manufacturers instructions regardless before cleaning any heat exchanger? Thanks Derek👍🏻. Top video. Asian Jon. Training.
There are two levels of service, the legal minimum where engineers clean the condensate and take a flue analysis, if its good, they are good, if its not good then they will do what is termed a full strip down service.
Typically, the plastic is just the carrier for the same grains as in normal sandpaper. So, you just sanding down the surface , removing the protective oxide layer
Derek, people like You, makes RUclips Great!

Good call 👍🏻
Put a bit of pipe on the shaft (extension) to give you a non-rotating grip on the shaft.
Good shout 👍🏻
Fantastic. Another good tip for gas engineers. Thank you very much Derek. 😀👌
Great video. Links would be good to the items Derek. Keep up the great videos

Muy interesante tu vídeo donde puedo comprar el cepillo que utilizas con el taladro. Gracias un saludo desde 🇪🇦

Hi,Where can you get a drill extension like that please?
Thanks as always
I got it from Amazon 👍🏻
@@tomkatgastraining got a link
Another brilliant vid.. Just some links to the tools mentioned pls
Brilliant video, thanks Derek👍👍👍
Thanks Derek.
Thomas Bradwell
Thanks Derek
Where did you get the cleaning brush
EBay I think

Old out new in
Thanks Derek great video 🙏👍

This only cleans the 20% you can see, it certainly looks nice afterwards but the scale will be on all exterior parts of the heat exchanger.
20% clean is better than 100% dirty
Brilliant vid 👌🏽👏🏽

Hello, I'm following you from Turkey, can you turn on the Turkish subtitle feature?
I will try
@@tomkatgastraining I want to watch it with Turkish subtitles, I don't know English
@@tomkatgastraining hello, i don't know english, can you choose the option with turkish subtitles?

@@mehmetaliciftci3495 I have no idea but I will find out how to do it
British gas have serviced my boiler for years and never done this.

Great one from great person
Great video Derek, can you do one for Worcester boiler, kebab style and other. Thanks 🙏
On the to do list mate 👍🏻
@@tomkatgastraining look forward to it
I find a nail brush works well.
Marcin Masalski 👍
I wish more engineers would do this and not probe n go.
👍👍👍
👍🤓👍
Should have a mask on cleaning that shxt off Derek but nice video anyway 👍
Yeh should but doesn’t make good video. The sacrifice I do to make a video 😜👍🏻

Scratching a stainless heat exchanger is bad. Will cause premature failure.
That’s why I used a plastic brush not a metal one
