Brilliant video and Voiceover... Now that I understand my boiler I can now sort out what plumbers haven't managed to do. Huge thanks...

Really handy info about fan running time and sticking bearing plates, thanks Allen!

Great video once again Allen, i never get bored watching your channel. Thanks to both of you.

Great video , very helpful to run your system efficiently. Thank You

Brilliant video. Love watching and learning from your videos Allan .

Thanks Allen and Paul, good info on what can get you perplexed with the codes!!👍👍🍻🥳

Thanks for doing these vids, really interesting and helpful, they are helping me improve my knowledge please keep doing them 👍

Great vid, great tips on the Worcester Keep them coming ALLEN

Great video, although I like many others do installs as well as boiler repairs it is still beneficial especially for those who only do installs to set up the boiler to optimal efficiency.

Very useful video, thanks for posting it.

That was one of the best instructional videos Ive ever seen

Very informative once again. Thank you.

Quality output from you Alan 👍

Hi, you've just saved me from buying a new boiler, the overrun 120 seconds for bearing plate condensation has fixed the problem 👍

Many thanks Allen,for a well informed video

Very useful information, thank you.

Top video keep them coming it well appreciated

Thank you. Very informative 👌

Great video very helpful thanks.

Thanks Alan great vid, I’ll be downloading that manual

They've defo got into you as some of your vids you've hit them hard. Lovely vid al x.

Thank you for sharing... Very useful. 👍👍

Really detailed video, thanks again

Another great video 👍

Well yet another great video

Not keen on Worcester I'm a Baxi man but this video was really helpful for servicing, thanks Allen

Just made the suggested adjustments to my GREENSTAR 30CDi

thankd as always very imformative

Nice one Allen useful video

Brilliant video keep up good work 👍

Another great video! That info is really useful 😀

Great video 👌

Thanks Alan and Paul

Thanks it always useful

Thank you for the information

Great stuff.

thanks a lot Allen

Useful video, thank you. Just wondering how to set the flow rate please?

Nice one Allen

Thank you for information

Helpful mate✔️

Brilliant thanks

Thanks for this

I always think a good visual demonstration is worth a lot more than reading about it . If increasing the fan overrun time dries out the bearing plate why is it not set to this as a factory default?.keep up the good work .

Thanks Paul

Hi Allen Great Video - Any chance you know what the minimum flow rate for these boilers should be? Have a 40CDi Classic feeding one mains pressure hot water circuit off a two port valve and then two rad circuits (top and middle floor) each off their own 2port valves and then two underfloor manifolds, off another two 2port valves. All rads (except bathrooms) fitted with TRVS.... But i am struggling getting the boiler/circuit to manage all the pressure combinations and actually stay fired up when circuits are on/almost up to temp... Boiler keeps going up to 75 degrees (setpoint) and overshooting, turning off, pump continues and finally the boiler comes on again before repeating same. Effectively the boiler is not actually on that much :( I think it is related to flow issues so trying to decide what and how many auto bypass valves to fit (but need boiler flow rate to work this out)

Should the green burner light be lit up when the heating is turned on? My turns on when the hot water is running but not when the heating is on.

It will help me a lot on Worcester breakdown! Thanks Paul and Allen.

Hi Allen, I'm just a consumer. Can you tell me please, does the pilot light need to be on all the time (ours isnt) or is it self ignition? Thanks for your support.

Thanks paul

Thankyou very interesting

Where is the section on connecting to the weather compensation BB ports?

Hi, what are all the other settings for?

Can you let me know which model of CDi boiler is this ?

Very nice video.

Top video

Does it lower the minimum kw ?

After 5b to 120, go to 9d on 2nd level diagnostics. It is the fan speed, turn from 50 to 55 and this also helps to dry the bearing plate. Also, 6d on level 1 diagnostics will show the dhw flow rate.

Great video Allen, any chance of paul doing a video of servicing a greenstar i boiler and sharing a few tips.

Can you range rate a Worcester 24i system boiler ?

Dear Allen I'm a very old commercial heating engineer but have fitted all brands and fuels of domestic postage stamp boilers as well as light commercials in Whitbread pubs 50 mile radius of and including Nottingham etc. I have been looking at and advising a very cleaver electricai designer and his wife our niece, a leak or two on their Worscester CDi 37 combi they have in their loft. It has good access but the system should have a few improvements done by someone qualified, who is very familiar with Worcester Combi's of this type. Please do you know if that boiler has a safety = water low pressure switch that should prevent the sequence , even the pump from rotating in addition to the overheat stat? The pressure gauge on an 8 year old boiler same as usual can stick as this one does so I've advised a new replacement. I said the pressure needs to be known! I managed to turn the plastic top to stop the auto air pressure switch as it was passing again a notorious regular possible fault. I advised due to him being electrical to fit a warning device re the water pressure if it looses pressure an easily seen light or sounder as the boiler is not visible from below. With not being able to see a low water pressure- switch within the boiler Installation instructions, I would think there is not one (shame on Worcester) but it would be most helpful that you may well confirm our thinking that indeed there is the lack of one. Best wishes ( I'm very please I don't now have to sort out these complex hard to work on nightmares of a boiler!) full of plastic components.

Hi I've a Worcester 35cdi I've set the boiler control on no. 4 is that OK or should it be higher for a 3 bed house temp on thermostat is set to 20.5c

Thank you

i have a junker 30kw but i dont know how to adjustit the functions a1a2...can somone explain which is for what and should be standing on those?

Helpful video but no link to the manual. Searching the Worcester web site I can only find the service manual which doesn't cover the service menus. Can anyone point in the right direction?

Are boilers usually wired on a spurred fuse and is this usually fitted by the plumber?

Must you do another Telegan flue anaysis once you finished with the settings changes? I assume range rating is affecting the combustion?

I’m having issues with a new green star Bosch 150. Showers run hot for 5 minutes then it goes Luke warm then gets hot again any ideas

Great tutorial, the only issue as service technician and as a customer it gets very frustrating waiting for parts on on all these new combinations and tankless systems are . Way too many moving parts IMO . Every manufacturer makes these units so it’s kind of a nuisance when you have to wait for tech support , as well .

We have a 30 CDI but we were told on installation that the right hand side rotary control is redundant! This video shows it in use? So, is there a component missing in my boiler?

Does anyone know....How do I get the pilot light back on? Reset many times and still no pilot light..

Tnx

If you use the range rate, does the boiler come down to the same ‘lowest’ rate? Essentially, the boiler will work between a closer band, ie, 6-16kw, rather than 6-30kw.

Hi allen, Is there anyway I can contact Paul? I have a problem with my Bosch CDI Combi boiler. Many people have come and gone but cannot fix it. Thanks

Great Video Allen. Could you advise so I could try and get maximum efficiency please? 1A = was set 100%, reduced to 70% to reduce max firing and cycling. Circa 17kw on DHW cylinder primary coil and estimated circa 20Kw heating required to house. Say allow 20Kw - 20/30 = 67% allow therefore 70%. 2B = Max CH temp currently set at 88C (factory default), could this be dropped to say 70C to allow cooler to touch rads, less cycling and slightly more efficient? Whilst also maintaining 70C to DHW coil (60C DHW set temp / 65C storage temp) I'm assuming the display temp on the boiler is the flow temp - therefore I'm thinking circa 70C out circa 50-60C return to allow maximum efficiency?

How do you turn the boiler on once you have switched it off

We've just had a smart meter fitted and the engineer switched the boiler off. Now the boiler (34CDI Classic) is running pre heat. I've downloaded the manual and read the instructions to deactive it but it doesn't seem to work. It says hold holiday button down but there's no response. No faults showing, just non responsive holiday and eco button

my output for the central heating is 77, will not go above this, going above this well set to back to 29

I have this My hot water is not running How do i get the hot water running again

Can I have the link please

After finishing the adjustments with the chimney sweep function button, do you press the service menu key once or hold for 10 seconds to get out of that menu? Thanks

How do you use the time dial?

Great video how do I turn up water temperature on my worcester cdi classic

Hi, how do you re-ignite the boiler?

I wonder if anyone can help...our reset button flashes and the number on the display gets very low, so we reset and everything gets back to normal -the number goes up to 60ish ,but then the number keeps dropping again... any ideas anyone?

I’m still confused about having my heating on. If I would like my house to be set at 18°c how should I do that… I’m not really understanding 60 kW that makes any sense… 😢

Thanks so much

Why Worcester is so complicated? Who agrees??

How do i setup to have hot water all the time?! It only works sometimes … not sure how was set

The manuals are as clear as mud.

How can I join your group training

Why does Worcester not put a 4inch hole on their templates

👍🏼
