I hope you are keeping good and well John.We miss you and the brilliant videos and information you gave us all. I hope you see this and say hello.

Gold dust knowledge thanks for sharing

Good common sense training

Great video

Plastic plugs in unused orifices led to call-outs on two separate occasions due to water spraying out of the plugs. 🙄 Prior to this, Ravenheat were good with their warranty, they changed pretty much every component on my boiler. Now struggling with code E41 which relates to flow and return temperatures being too far apart, potentially some blockage in the pipework. Is anyone familiar with this? Maybe it's time to replace it after just 5 years. The wife has fallen out with it 😢

Could have offered a 60 year guarantee, means jack now they’ve gone bust

Thank you sir.

Im not a plumber or heating engineer, but i loved this guys enthusiasm Great tutor

Come back, John !

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.

Down South East hard to find merchants stocking these. John it looks good and I know you have been working hard on this. Good luck with Ravenheat.

Good trainer, can't beat enthusiasm

John, you are brilliant, very clear explanation, I really wish you keep going with your trainings, Very thanks to you

Thanks the best explanation of testing air pressure switches I've come across. Cheers, mate. Please keep the quality content coming 👊

Great content 👍🏽 Thank you

Hi guys have you a merchant in Northern Ireland.

Superb video

Brilliant , you obviously love what you do with a passion, you just sold another one.

This guy is awesome keep the vids coming great content very clear

We love ya John Keep the videos coming

So glad I watched this.. I had our boiler apart 3 times trying to figure out why the hot water wasn't working. Had replaced the mixer, the diaphragm and was about to replace the diverter.. Turned out it was the thermostat in the upstairs shower was making its own circuit between the cold and hot !!

I've seen this video over and over brilliant 👏

Very clear demonstration. Thank you.

Do I need to be IT expert to get into parameters

Thanks, that was helpful

Very nice....never thought raven heat would be so easy to work on 👏👏👏

👏👏👏

👏👏👏

Quality demonstration of service process for electrodes 👏👏👏

Great video! Thanks :)

great videos - even just for entertainment purposes.... are you still with us John?

Pcbs are bullet proof? Must have never seen a suprima then. A slight breeze let alone a bullet....

Cheers for that really helped! You got any good videos on FGA readings and what is acceptable or not; especially difference between older and newer boilers! Ta

I've had my HE85 for 11 years now. It's broken so many times (darn those capacitors on the fan control board). However, over the years it's become a labour of love. I know everything about it, all the ins and outs. These videos really are the cherry on the cake for me. Thanks John!

I love the look of the compact BUT I cannot find a supplier or fitter in Monmouthshire. I have tried to contact Ravenheat direct with no success. Any ideas

John U r such a great explainer

brilliant - i had used rotary wire brush and sandpaper to clean - useless, take his advice and rag it with a file

No sharp edges that’s a winner straight away. To be fair looks like a decent boiler. It is true there’s a lot of badge snobbery

Why aren't famous Leeds plumbers Allen Hart and Michael Goodall pushing your superior boiler, designed and manufactured in their home city? Their social media channels have been quiet recently on your boilers. If I were you, I'd want to find out what's going on with them, you should address any concerns they have got. Because customers are going to be wondering if there is something you are not telling them. Ravenheat is superior to Viessmann because they use copper pipes, not rubber hoses. Ravenheat are superior to Worcester because they use a brass not composite plastic hydroblock. Ravenheat's single pass stainless steel heat exchanger is equal to Viessmann's. The electronics are located in a plastic unit, protected from any leaking water. So what is not to like? What I have not heard about is the reliability of the electronics and ease of fault finding. I haven't heard about the secondary plate heat exchanger either but I am assuming their waterways are no narrower than other brands.

Point very well made here. Clean the burner!!!

Excellent.

Looks like Vaillant/ Worcester, best of both, top design
