Boiler "Gas Rate" & "Gas Pipe" test is easy, I show you how

Every time a new boiler or any gas appliance is installed the "GAS PIPE SIZE" has to be calculated to make sure it's correct and safe. If the boiler stays ON for long periods it could be UNDER gassed thus high fuel bill will follow. We must also test the "GAS FLOW RATE" to the manufacturer requirements to prove 100% efficiency (often not done) thus not safe and expensive. Only a Gas Safe Regist...

A Cold rad fault is either AIR or a faulty TRV. Version 2: 24 01
My Danfoss HW/CH controller is located in a quite awkward position (low in airing cupboard) which makes it difficult for me to bend down to and see it. I like to put HW on as and when I need it, so I need to regularly access the controller. I want to relocate the controller a few feet outside the cupboard to a much more convenient position. Before anyone asks, no, me hiring a professional to do the job is not an option due to cost. Basically, I need to (safely) extend the wiring (making sure each channel wire-extension goes to the right place in the controller, yes? What's the proper stuff (wire and connectors) I need for the job....Anybody?
Hi David, thanks for asking, controls wiring is not for DIY because you are messing with 230vAC which is dangerous. Please trying find someone who has a certificate of attending a course, shop around there not all expensive maybe pay by instalments. I have seen your installation too many times, (I used to charge £200 to rewire now its £300+) 1st power OFF to remove the cover take lots of fotos which terminal has which colour wire, do the same with any junction boxes, Start with the easiest PUMP wire where does that go? Make a drawing, Cylinder / room stats do the same, Look at my VIDs on wiring a room stat Y / S Plans, have the book or get the APP. Big danger is BLUE neutral wire are they being used with voltage, if so that MUST be rewired, not allowed and dangerous. If the programmer is over 8 years consider 2 channel RF, see my VID. that is easy and will save you money more controllable HW & CH.good luck, George Staszak 😀👍
@@mrcombiBedford I know how and why to cut the power. never mind
@@davidadiwego4608 No problem👍
There is another fault. I wonder if anyone else can figure it out.
No please tell us😗
Hello, great video, but can you show testing the voltage going to the gas valve, as on some boilers I find it almost impossible to get the probes of my multi meter to make a good contact. Thanks, Adam
Hi Adam, thanks for that and you are correct too many boiler parts are fitted badly making testing very difficult or even worse difficult to replace, but no one listens to me. What I did was to order new meter leads with very thin probes (BG engineers have them) shop around, shorten the metal probes to 10mm just enough to fit on the PCB connection which is where I did all the testing not on the component, much easier and faster. Hope that helps, may do a video on this.🤩👍
@@mrcombiBedford Thank you - yes it does help and I’ll follow your advice. Btw I came and did your fault finding and wiring courses quite a few years ago when I first started - both very good - I might come and do the fault finding one again sometime as I think I’d get more out of it now I know a bit more. All the best, Adam

Cześć Kamil, thanks for the comment glad you liked it, the Krakow video is due next week, please subscribe for notifications, all the best. Jerzy 🤩👍
sir I have a question, this aqua signal ignites the gas boiler but is it a continous signal or just a one time ? the reason i am asking this is , i am doing a project and i have connected a electric heater to heat water but i dont want to run both heaters at same time and want to save my gas money so i figured if i just block this aqua signal , i can stop gas boiler from igniting ! so please if you reply it will be a huge help ! thanks in advance!!
Hi, thanks for asking, All combies have 2 switches 1 for HW and 1 CH which are NO (normal open) dead, until a tap is turned ON. There are only 2 ways to start ignition 1 sensor (Ohms) the PCB see's a change and starts up, or 2 a switch is activated from NO the NC (normally closed) and the boiler starts up until the tap is turned OFF then back to NO shuts down. I don't understand why you want to connect an ELX heater as it's 3 times more expensive than Gas? You can just unplug the aqua sensor from the PCB and enjoy big bills. If you want at add HW cylinder see my video on add 2 zones to a combi or any boiler. hope the helps, George 🤩👍
Without a doubt it is an excellent app, it helps me a lot.
and how do you feel in an era of 'Smart TRV's' - eg the HIVE / Honeywell digital ones
Hi again, Smart TRVs are very expensive Amazon £274.00 for 5 heads is completely unnecessary because the payback cost will never happen, EVERY rad needs one, just like Air source / Solar and EVs 👍 Smart controls 100% save money balancing TRVs, Heat loss of the home / lounge 60c flow is the way to save money. Why some people spend 1000's to save what? When I added what I paid into my pension I have to be 117 before I make £1.00 profit. I paid for their big building and bonus. Hope the helps, George 😀👍😤
@@mrcombiBedford okay. lastly one more question. if you have smart thermostat in hallway and radiator, you said it should be fitted with a trv. i was under the impression area with thermostat shouldnt be fitted with trv. otherwise both will compete, and also there is no 'bypass' for the boiler incase other smart trv's are off when the heating might be commanded
@@mohitl1697 Hi Again, no problem, as always every rad needs a TRV if the stat is in the hall a TRV must still be there, in a ROOM not allowed both. Ignore what is in the boiler has fitted, as I say many times the rules and Codes of Practice and CONTROLS firms demand an external auto by pass on EVERY system. It's the CONTROLS firms demand an external by pass NOT the boiler manufacturer. Installers wrongly keep thinking it's a boiler requirement when it's not. take care, George 🤩👍
What about Sentinel X1000?
Hi, thanks for asking, the X100 or Fernox F1 are very good inhibitors I highly recommend refilling with them if the system has been correctly. If not X200 or F2 are a more for problem solving, eg. noise or blockages pump problems which is often the case. Hope that helps, George 🤩
2:47 Shame I can't see numbers 4 to 9 as they're covered by a thumbnail for the next video. 🤦♂
Hi, Jaffa, we all live and learn, thanks for the comment, George 🤩
Short circuit test... Shouldn't the reading be over 20 ohms 🤔 If under 20 ohms, then there may be a fault on a component...like fan or Pump 🤔😉
Hi 33, thanks for asking, over because we have to have a HIGH resistance to stop fuses blowing, 100 Ohms is the standard value that we work to. It should be O.L. (over 1 million) but some firms don't use the PCB the same way. Hope that helps, George 🤩👍
@@mrcombiBedford thankyou
If it's that good no more heating engineers
Hi Nick, thanks for comment, because of a shortage of engineers who get richer and richer this will only get worse for customers. No one wants to do this job, shame. all the best, George 😍
Hertz.....I don't understand either
Hi Dickie, thanks for asking, Hz is not just used as a radio or TV frequency but it's the best way to measure a pump / fan or anything that moves. I found Vaillant publish lots of data in Hz. A pump can be 2K revs but we can't measure revs. but we can in Hz. which is 100% accurate. Most will use Ohms and volts which is OK but Hz is faster and more accurate . Hope the helps, take care George 🤩👍
This is a horrible idea.
Hi Derick, thanks for your comment, take care George 👍
13kw not enough for a house ? Enlighten me please ?
Hi Michael, just going to have lunch, a mid Poz. valve has a gap of about 18mm to the heating side, that only allows 13kw of rads, its recommended only 10kw because the big double K rads at the front of the house will not reach max temp 75C the result will be the boiler stays on much longer and high fuel bills. Remember it's the boiler RETURN stat that switches OFF the boiler. It's better to over size the rads with a LOWER return temp. use my "Heat loss App" and you will amazed at how many rooms have under sized rads 22mm Zone valve can have about 20kw of rads recommended max 18 better to split the system to 2 or more zones to lessen the boiler stress and much cheaper to run. Thanks for asking, Marmite crumpets are go! 🤩👍

Thanks for liking, take care, George 🤩
Mr Combi, great channel with sound information thanks. Can you help me with a solar thermal tank project. I have a Valiant Ecotec which is a cracking boiler, I am fitting a thermal solar tank. Now some boilers can take the preheated water in and top the temp up and others can't. A blend valve to limit the input temperature is suggested on some installations. Now can I feed my boiler from the tank or can I tie into the hot water pipes via a diverter that favours the solar if hot enough. Thanks for any info and thanks for you straightforward presentation.. Best.
Dear Woffy, Thanks for the kind words, not an expert in that field I would go to Vaillant for advice. Don't like air source or EV's I would never take any advice about heating or cars from a politician. All the best, George 🤩👍
Hi I have just bought the fault finding app from Apple app store and none of the videos play. How can I get a refund please. I have try emailing you from the app and the email was returned saying couldn’t find address
Is the fault finding book the same as the fault finding app because I use a tablet when I’m out on the job. Plus a few people have commented on the videos not working on the app has this now been fixed. Great content by the way
Thanks for the question, the book has a lot more information we always advice have both books and all the APPs. if you are an installer or breakdown engineer. The APP has 21 "How to" chapters the book has flow charts, No ignition and so on. The 2 video APPs are being updated hope to be finished in a couple of weeks, (the icons are amazing) Don't download until done, the other 6 will be next. All the best George Staszak 🤩👍

I wish you showed how to replace that old thermostat to the new o, and if we have to connect the same wiring, 2 live 1 neutral plus sensor.
Dear Gixxer, thanks for asking, I cannot show you how to wire a digital stat because each firm has different terminals, you would not change to the same type, 2L +N, all digital. have COM and SW.Live same goes for Open Therm. some will be 230vAC or 24vDC or Volt Free it depends on the one you buy, as in other Vids. if your boiler has O.T. that's the lowest running cost after that VF then 24vDC avoid 230vAC. hope that explains. Our Wiring book and APP has more info. take care, George Staszak 👍

Hi George. Just sidetracking slightly but I have a customer who upgraded their Landis & Gyr roomstat to an RF EPH stat but didn't want the old stat removed. The installer set the old stat to max and told them not to use it but use new RF stat. This is correct as far as I'm aware but I think they have been moving stat probably due to habit. So, going to link wires behind stat just wanted to confirm which ones to link out. Thanks
Dear Gas NW, Thanks for asking, yes you are correct the old stat MUST be disconnected, I understand they don't want to remove the old one before decorating. Power OFF and remove the wires from the boiler end and make safe (don't cut them OFF, someone may want to reconnect them later). Hope that helps, George Staszak 🤩👍
@@mrcombiBedford Hi George. Many thanks for the information. Its an old heat only boiler so will I need to put a link back in on the boiler end so that the EPH twin channel programmer controls the switch live to the boiler? Thanks
@@gasservenw1369 Glad to help, it's only the feed to the old stat that needs removing at the boiler end as you say.👍
I feel my radiator nearest the boiler get slightly warm when running a hot bath. Is this normal for a combi? I think it's done it since I moved in 12 years ago
I think I replied earlier, but its the diverter letting by. thanks for asking, George

that's vaillant off my list then. my ideal has a preheat button which you press once and it puts preheat mode on - none of this press triangle square and x, hold left joystick down, count to ten, turn round and touch your toes nonsense.
Tinnitus, have had this for fifty years and it is my annoying friend !. Very important you don't focus on it, accept that it is there and get on with life. Mr Combi has given some good suggestions and I use these techniques to keep the tubes clear. The Eustachian tube is normally closed but opens when we swallow, yawn or chew. This allows air to get into the middle ear and any mucus to get out. This keeps the air pressure equal on either side of the eardrum. Having equal air pressure on each side of the eardrum - and the middle ear free of mucus - helps the eardrum to vibrate. This vibration is needed for us to hear properly. My analysis of some forms of. Tinnitus can be the reproduction of a tone which you have had long exposure to including something like a computer fan, for example you hear a constant tone in a space from something, the brain counters that like noise cancelling earphones and turns down the gain for that frequency. When you leave the space the brain no longer hears the tone and but is still cancelling the tone but as it is not there you hear what the brain is producing. Don't Focus on it and do speak with your Doctor about your hearing. Good luck I am taking my friend for a walk..... Good advice Mr Combi
Well done . Best explanation so far

Hi what causes gas rate to be too high and over what manufacturer states
Hi Jez thanks for asking, its the gas valve, after a few years it get out of settings and often does not close promptly thus sues more gas. sometimes it just shuts down, dead. Often it's replaced with a different model same as PCBs, that's why I say after 4 years check the firm for updates. take care, George Staszak 🤩
@@mrcombiBedfordHi George, I’ve literally been noticing this issue with Ideal Combi2 boilers. Mainly with the C24 model which when running gas rate checks seem to be sometimes about 3KW - 4KW overgassed. Maybe they have a gas valve issue with this model as these are relatively new. Also would a faulty PCB cause a higher gas rate?Thanks, Dan.
@@DanielGreen_690 Morning Daniel, not the PCB, 1st. call the firm to report the issue feed back is vital to them and ask for guidance.

Thanks for this helpful video but in the places (8 mins 35 seconds onwards) where you talk about the blue wire, we can't see the wiring mistake you are referring to in the video and the discussion about the blue wire is not clear. Could you please show the wiring of the old thermostat that has been done incorrectly and the new correct way for a digital thermostat. I have just installed a digital one(Siemens RDH100) and I used only the yellow and red cable because those were used in the old Honeywell I was replacing. The blue wire was already cut off but not sleeved or taped up. I replaced the Honeywell because I was suspicious that it was not turning the heating off in time. So potentially overshooting and strangely it was also not turning on the heating early enough either.
Dear AR, thanks for asking, I have lots of drawings in other vids APPs and book, that shows what you are asking. The old 230vAC room stat has to have 3 wires, the neutral we don't need in digital stats so we make it safe and use the other two as they are Com and SW.L. Hope that helps, George 👍
@@mrcombiBedford Thank you very much George. I managed to get the thermostat installed using the 2 wires. I am experiencing that under the stairs location problem though. Even in June, the temperature under the stairs is dropping to 18 degrees, causing the heating to turn on. I think I need to configure it for a 2 degree differential so that it only switches the heating on when there is a 2 degrees difference. Thanks again.
Thanks for asking the blue wire is with the black wire that’s wrong All the blue wires should be together and never with others Hope that explains George
شكرا جزيلا لك
Dear Mjido, please translate to English, all the best, George
Hi George, If you don’t mind me asking, how come you don’t the in-person courses anymore? Could you recommend where I could go? I’ve just finished my MLP and while your books and apps are very helpful, I need some hands on experience. Many thanks

@@mrcombiBedford Hi George. Many thanks for getting back to me. I’ve got the apps and have just ordered the books. I will hopefully be attending the manufacturers courses as you have advised once my ACS comes through. Drayton and Honeywell only do online from what I’ve seen. Many thanks
@@IncredibleMet Unfortunately that's the norm, it is very expensive to invite 12+ engineers and feed them etc. and a lots just don't turn up because the cost is too low. One firm told me of the 12 booked 3 came, a lot of food was wasted plus 2 Reps hotel bills. This is why they stopped. Take care, George
@@mrcombiBedford Hi George, I’m having issues with the apps. I’ve emailed the app support email. Would appreciate it if that can get sorted quickly so I can start learning! Many thanks
@@IncredibleMet Dear Met, We are still trying to find which code has been deleted, We have a plan B and I will get in get in touch. Thanks for waiting Sales 👍
Thank you very much, for a very kind explanation.
Dear Muwafak, thanks for the kind words, glad to help, take care, George Staszak 🤩👍
Hi, my hot water pump is constantly on even though the hot water and CH is off. I changed the motorised valve but the issue remains. Any idea? Thank you
Dear kr173sh, Thanks for asking, who told you to change the diverter and how did you test it? If the pump runs in HW the stat is still calling, see my videos on HW and Diverter faults and how to test parts. 🤩👍
@@mrcombiBedford the plumber said the micro switch was sticking and to change the valve. It worked for 2 weeks but can to square one.
Very good, excellent, now call him back to fix it, he is very good👍@@kr173sh
@@mrcombiBedford should the water pump be on when you turn on hot water on the tap? (with the central heating off )
@@aixalexander5257 Hi Aix, I am not understanding your question "water pump" combies do not have water pumps. 🤔
how about, pump makes litteraly 0 noise? and still not working, not even the pipe hot water aint working which i supose does not relly on pump... wtf is wrong with that stupid thing... It starts burning, it starts heating water, then you can hear the switch and immediately shuts it down, and the 'sand clock' diode keeps blinking
Hi Nikola, Pumps and heating systems must NOT be tested in HW mode only in Heating, because it tests the diverter valve has moved and many boilers do not use the pump in HW. If the heating is OK then the FLOW pipe gets hotter, if not either call a breakdown engineer or factory Tech. Dept. All the best, George Staszak 👍
