Best explanation on you tube regarding combination gas boiler!!!

I'm 20 years as a gas engineer but still enjoyed watching this for a refresher 👍

I thought you were either going to sneeze or burst into tears during the first few words

we need more training with Roy & Allen on this channel

Great video and One of the best explanation of combi boiler that I have ever had. Thank you Sir's, Lord bless you.

Big Roy = Topman! Brilliant trainer, definite more of his vids please. Thanks for all your efforts Allen.

Fantastic, now I know how they work. Roy is very good at explaining every component. Well done mate, if only we had a PM who knew what he was doing.

That video is excellent. Roy is a phenomenal trainer. Top class

That was probably the best well explained video on a combi boiler I have ever seen. Roy’s knowledge is next level I don’t think he took a breath the whole video 😂 looking forward to the next. Thanks both for sharing your knowledge .

This is a fantastic video. 2 years ago I somehow passed my level 3 gas in college but the tuition was absolutely terrible. Since passing I have never had the proper knowledge to do my. Own gas safe so I ended up into the HIU game. Watching these videos breaks everything down and gives me the confidence to take my gas safe exam as its very transferable to HIUs. Thank you Allan, your videos are truly educational. Keep uo the good work and your friend in this video is amazing

As a mature student who is working full time and trying to squeeze my college ACS in plumbing and gas into my busy schedule, your output is hugely beneficial to me...particularly as the college is closed at present. My learning curve is incredible and it’s down to you and people like you. Thanks very much Allen 👍

These vedros are brilliant..far better than some of the courses iv done..

Thank you Allan. Your time spent compiling these videos are a godsend. To the young and old up and coming engineers we salute you. Kind regards Mike.

That's one of the best and most constructive explanations of what all the parts of the boiler do. Excellent lecturer.

Did a course with Roy at Baxi Warrington, absolute top man, top trainer. Would love to have 10% of his knowledge. Great video look forward to the next cheers Allan for providing 👍

Awesome yet again Alan. Many thanks to you and Roy taking the time to make this.

I feel like learning on line . Thank you very much Gentlemen 🍻

Excellent video! Thankyou! Taught me more than my ACS.

Very good. It's a real skill to be as concise as Roy was/is. A big thank you to both Allen and Roy.....would love to see more. Yours Grateful Chris.

Absolutely excellent explanation of the component parts of a Combi. Learnt a lot. Only comment is the term used for the 'small' input connector to the pump. Its a Pulse Width Modulation, not Power Wave Modulation connector. The controller sends a fixed frequency pulse to the motor on that connector. The width of the pulse determines the 'power' the motor develops.The connector also provides feedback to the control circuitry of the pumps condition

Great advice and much appreciated knowing all this. You can never get enough info as things change all the time. Please keep up the good work. I know I really appreciate it.

Hi Excellent presentation! Clear, concise & truly educational. What a bonus - more to come !!! Kind regards

Brilliant! Just Brilliant. Confidence is at high after watching this. Thank you lads, top notch video!

Fantastic video. I've done many boilers before, but mainly diesel and some wood on rural Portugal. It was good times. What I really appreciate about gaz boilers more than any other, is how compact and powerful they can be. It's the sort of simple tech that relies of physics and laws of nature to offer a great deal of comfort in our daily lives and can go by unappreciated. But the best thing about them is how they are the sort of machine that does this wonderful thing but can be so underwhelming to look at its insides when they're opened up. Love it.

Another great video, very knowledgable guy and well explained, one two great tips thrown in as well. Keep them coming Allen

Awesome video!! One of the best ones yet, thank you both for the dedication.

Great video, thanks Roy and Allen. Brilliant efforts all round 🙏

This one of the best video I saw Thank you so much God bless you and your family please and please we need more of this kind of the video to be the engineer and look after our customers, all this because of learning from your experience

👏👏👏 Cheers Allen & Roy... I remember the baxi 600 strip down you done Allen and just like this as Roy done very informative....Great knowledge of boilers.

really enjoyed roy is very good at explaining how it works and sorting our misconceptions thanks alan and roy

Awesome video, straight to the point with the right amount of information. 👍🏻

Fantastic Video its clear and concise for those who new to the industry

Late to the party but absolute cracking Vid, great to see Roy passing on his knowledge to others it can only benefit the industry, guys on the ground though really need to start charging realistic prices respect "their" trade and not become part of a race to the bottom. Looking forward to more, Thanks Alan & Roy for taking the time to make this.

Excellent clear and concise video Alan, future video on extra protective devices such as filters , air separators , auto air vents shock arrestors etc what they do how they work pros and cons etc etc I know you have already done some vids separately.

Absolutely superb

What a clarity.

Great video 👍

Hello, you are giving very good technical information. I wish you would add the description feature with Turkish subtitles, I don't know English. I write this translation as an English translation on Google and throw it away. It would be greatly appreciated if you add the Turkish subtitle option to your videos

Id like a video on how to link out the external controls on a boiler at the pcb. such as the timeclock,room stat etc and how to test with a multimeter if the voltage supplied by the external controls is sufficient. It would be handy on breakdowns to verify its the boiler or the external controls at fault. Brilliant video by the way

Top man is roy! Deffo one of the best trainers in the game! He looks like he has lost alot of weight.

love it thanks

Great video roy and Allan

Excellent video
