Thanks Derek
When I watch your videos it’s look like I’m in my own class.u explain same like my gas instructor.i love to watch your videos.always helpful

Absolutely right on doing a tightness test on a service. A proper good job!

Excellent service explanation and demonstration. 10/10 buddy.👍👍👍

Had a company ask me to do some services for them. The usual thing " we look after loads of properties in your area"  They wanted 12 to 14 services done in a day. I told them that  there was not enough hours in a day to do it correctly and they said they wanted them doing as per manufacturers requirement and I again said that could not be done but they CLAIMED that all their other engineers did not have a problem doing that many. Well needless to say I did not accept and there is no way they are being done correctly at the prices and time scale they were asking. This is a major area of concern as corners must be being cut. Even BG I have seen go into a boiler and just test flue gases only and if they are ok do no more and on occasion not even removed the cover if the flue gases are ok. I could not sleep because even a pass today could be a crumbling seal that perished the next day.

Corrrrrr look at that cooker! Thank you for this, many notes taken. :)

Quality work Derek, great stuff! 💪💪💪💪💪💪💪

Great video Derek love it😊
I love when some companies ask you to do 12 services a day unreal….

Thank you so much, you have helped me a lot. A gas technician from Greece

Thanks, Derek I enjoyed the full procedure. Very educational and enjoyable

Excellent as always.

Thanks for this video. Just had my first ever gas safe safety audit. (Previously been in companies up till now) This video was invaluable as I was examined for domestic and most of my past has been commercial. Passed no problem. We all have our wobbles in life. Confidence can go up and down and I know from your recent video you have had your training questioned. I mention your videos. The two gas safe assessors knew all about you and didn't have a bad word to say. FYI. They assess two guys a day. Kind of tells you a proper service check should take as long as it takes and that isn't an hour ! Or 15 mins like a British company have been accused of taking ! By the way Gas Safe specifically asked for tightness test checks

Great video. I would probably check flow and return temps before FGA.

Thanks…

Nice video. The copper grease is a high temperature grease. Sometimes nuts can seize when they get hot for long periods. Use then on car brake pads and exhaust manifold bolts 😇

Hi Derek it’s like copper grease and it stops the burner/ heat exchanger from creaking :)

Nothing like creating an expensive annual service !

copper grease and 7nm for the burner nuts, great post sir. and no i doubt many will cover everything you showed. So basically the new service is the pretty much the same as commissioning the boiler. Just to ad the flow temps adjust the condensing time of the boiler, so anything with a return of 55*c and below will condense but if the flow was 65 -70 it would just heat the room quicker and turn off the boiler quicker and still give 20*c difference on larger systems but not on a smaller 8 rad system. With a 50* flow i doubt your rads that are last in line will be optimum temp.

" It was working before you touched it".

grease stops the tapping sound when it is working

that flue terminal looked awfully close to the 300mm  boundary measurement
