Plate heat exchangers

Is there really a problem with the plate heat exchanger, or something that just looks like it? Ravenheat's technical service and training manager, John Wilson, explains the possibilities and how you can identify them.
Please note; the temperatures in this video are only used as an example. A working plate heat exchanger should be around 70 degrees in and 50 degrees out, with a 20 degree differential.

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

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.

Presentation is genius.

[@KevinJones-lx5ol]

👏👏👏

[@dzmalekvali1110]

Thanks, that was helpful

[@gregorydavison3421]

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!

[@mgomez8864]

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
