Baxi Main Hydro Explained. Dr pipe 

To take this amount of time to share this information especially to the younger inexperienced amongst is really soul uplifting... I don't know how you and Heating Geek have the time to do it... Keep up the good work.

Love the content buddy, thanks a bunch. Keep them videos coming

Thank you sir, i knew the sequence, but never to the depth you are talking about. A truly heartfelt thanks for your time and knowledge!!!

I am just starting out and these videos are exceptional thank you.

Nice! All brass - just as it should be. WB and Viessmann, please note. Thanks for another quality movie, Dr P.

Am so happy i found your channel very well explained thanks

Trying your best. And you are very much successful. Thank you for time, effort and resources for sharing this with us. I, very confidently can say that your videos of the hydraulic system of boilers are the best on the internet. Manufacturers should be very grateful for you as we are.

i'm new to the channel , but these are really clear and informative videos. many thanks and keep up the good work

Really enjoyed the video had to change my first diverted valve this week wish I had watched couple your videos first love the content only just found the page tonight will keep watching

Your a life saver glad I found you doing my course just now excellent content

Great video always wondered how the pump proving switch was made

Brilliant explanation

Well explained. Thanks

Good work 👍

THANKS boss, that is helpful indeed.

truly excellent explanation!

Great video

very good video

very informative thank you

Great video 👍

Great video! Really has helped me. Called out to a breakdown where both pins are rising when there is a hot water demand i have changed the diverter valve. Do you think it could be the filter on the hydro block on the right??

Nice video

Very informative video. I've got Baxi 80E. Replaced diaphragm but hot water is only at high flow rates which is frustrating when doing dishes. What else should I check?

It’s not a check valve. It’s a Venturi to give you the push pull motion on the diaphragm

👌👍

thank u for your video, very well explained. I got Baxi duo tec 28 DHW problem. I have changed Diverter, motor is working, Heat exchanger is cleaned, C/heating working, DHW is fine with C/heating But without CH not getting hot water. Can u advise me on this problem. Dev

Genius

If the bypass check valve had broken would that stop the pump prooving sw pin rising? What issues would cause a pin tgat didn't fully lift apart from diaphragm

Can you do a video on the sequence of a boiler and what parts do what? And any tips in general? Thanks

Very helpful video well explained,just like to ask how much water loss to expect when cold water in isolation tap turned off and both gauze filters removed for service cleaning.

Thanks again .Any videos of your tools coming up

Thanks for a very informative video. On our Main Combi 30 HE boiler, which looks to have the identical components here, during hot water demand, water is escaping to the heating circuit giving intermittent hot and cold water at the taps. On observing the diverter valve during operation, both the hot water pin and heating pin are pushed out but the heating pin stays out even when there is no heating demand, only hot water demand. Does this mean the components in the diverter valve heating portion are at fault or is it another component inside? The boiler and central heating has been power flushed less than a year ago and all else seems fine. The diaphragm in the front hot water portion of the diverter assembly has been checked and is in good condition. A couple of engineers have visited giving different opinions including change the diverter valve, change the diverter valve and the secondary heat exchanger and of course, change the whole boiler. Another said the plate heat exchanger was blocked. Appreciate any advice.

Dr Pipe! Visited a potterton today with this set up, will be going back again...it’s had replaced the div valve diaphragm & the section behind it, the push rod still barely wants to come out to make dhw switch...is this an issue with something at the rear of the valve or the pressure in the 2 thin copper pipes? Any help much appreciated for a vulnerable customer! Cheers

I believe that design of flow turbine is actually a plunger that rises as the flow it made.

Excellent videos' new subscriber. any chance you could do one o a vaillaint vuw 242e. Thanks

Been having an issue with my 105he that I needed to turn two hot taps on for the boiler to recognise the call for heat. 2 local plumbers came out both have said it’s the diaphragm. So got it replaced and the fault stayed. After educating myself I found the plastic cap (you unscrewed) on the non return valve broken off causing equal pressure to the change over diaphragm. Flow circuit non return valve (you said check valve it’s actually a non return valve) was the issue all along! £13.50 and all sorted. Super simple mechanical system. Fucking brain dead plumbers all just want a digital screen telling them an error code.

I changed diverter valve but wen I run hot water, left pipe heat up heating flow heats up

Main 24 HE filling loop is closed, but pressure gauge is over 2.5 to 3 bar upon which the PRV is releasing water outside. Would the culprit be the plate heat exchanger?

Can the CH water ever mix with the drinking water through the heat exchanger or anywhere else. On the boiler?

HI i have a Potterton combi that has a problem with intermittent hot water. some times it will work ok but will take some time to get hot other times it will not give me hot water then after some time will start to give hot water then it will go cold again then it will go hot and it will run OK but some times it will get very hot . some times it will run cold and not give hot water at all till you turn the hot tap off and then on again . what could be the problem ? the only time i checked the divert valve it had operated the micro switch and the hot water was working. it would be great if some one could give me some advice on what could be the problem ?as it is a bit frustrating
