Thanks for the information, having trouble with my heat exchanger at the moment, you make it far clearer on how heat exchangers work, thanks again , Gas/Domestic appliance engineer.

Brilliant explanation, I now understand what might be the problem..top work.

Excellent video on plate heat exchangers I learnt something new.

Very informative, did take my plate heat exchanger out but put it back as it was pretty clean. Wish i'd have watched this video 2 days ago.

He lost me when he said morning guys. I think I'll just get a new boiler. 😁

thanks for information. very important points

Very helpful. Thank You

I am subscribing to this chanel. Thank you very much for your video

Very good, where do you get that chart from

Thanks, that was helpful

Hi. Most plumbers jump to either a plate heat exchanger, diverter valve, or a thermistor, l hope I've spelt that right, we had hot then lukewarm water and boiler shutting down, it turned out to be a faulty cartridge in a bar mixer shower, isolate mixer taps taps and showers one set at a time and see if you get hot water again, when you do you will have found your pasding cartridge, worth a thought.

Have you got anymore videos John or anymore in the pipeline?

Presentation is genius.

hi john can you send me a copy of that thermister readings sheet

Come back, John !

👏👏👏

no thankyou sir

why are you giving technical advice in a public forum? Surely it should be in a Gas/GSR forum! Hope you have professional indemnity cover. Mores the point teaching the public how to mess with their boilers, which I find leads to all sorts of trouble!

Gregory Davison I don’t I agree with you . Problems who is creating them ??? . I am the public I had engineers servicing my boiler and I never saw one taking out and cleaning the heat exchanger. Now I know what a supposed professional engineer has to do . Very often are rude and do not explain the things they are supposed to do as they don’t do it ... they always advise you to get a new boiler, this is 100 % dishonesty . They just want more money from you. My boiler has been working well and I had a few engineers telling to get a new one . Except the last one I had who told me my boiler was in very good state. X finger still working well. Best regards María
