You’re a legend, sitting home for 2 days without heating and waiting for technician, the issue was heating valve, sorted under few minutes and heating it’s back woohoo 🥳 👍👍👍
Some OK tips but I would add a few more amendments.
Firstly the pump wouldn't be turning or have power to it (in most instances) if one of motorised valves was not opening/faulty.
So I'd recommend checking timer, roomstat, valves then pump in that order.
Secondly, the Lever on the side of the valves (particularly the honeywell ones in this video) are metal. This means they are conductive.
A large portion of valves fail due to an internal water leak which can result in these metal casing components of the valve becoming electrically live. This could put you at risk of an electric shock if you were to make contact with these components.
So if following the tips in this video just exercise a bit of caution.
Thanks Gas

Roger Bisby national treasure!
Funny how Roger and Robin both got sheared at the same time, I think they cut each others hair!
Roger, Robin and the rest of the team went to the barbers together, we got a crew cut.
Great advice and video Roger. Cheers.
Thanks for that! Followed your video and it turned out to be the motorised valve was stuck - now sorted, so much appreciated!
Excellent!
I get a bit nervous about people with no experience repressuring combi boilers, we know it's simple,but it's just so easy for them to not leave the filling loop open for far to long ,and then the prv start running outside hopefully,Another excellent video,am i worrying to much ,maybe ,but that's me ,
It is a consumer device and there is no reason it should be a problem. You might as well say the same about a tap
Terrible diction, very poor grammar but most of all, you cannot finish a comment with a Commer!
Putting the heating on now? No, no, no that's my Xmas gift to the wife.
Don't spoil her Al
Good video but a bit quick showing how to spin the pump with a screwdriver. For those who know, easy to follow but if you don't?
Should have shown the cover screw removed and the a camera shot of the small screw connected to the impela
Now your into the dark side of the game, where fitting a new boiler is all they know or are interested in. I fixed one the other week where 7 guys had tried to find a fault, but didn't, all being paid of course for the callout some coming back but didn't. The 8th guy talked them into a new boiler which was fitted. He got paid for the boiler a Ideal Logic 30 combi and nothing else. The water side did a power shower and one basin in the loft as it was a old system with a hot water cylinder plus tanked cold water, so running the bath did not affect anything else. This had 2 / 5 wire zone valves, both going back to the volt free link in the boiler. Took these two wires out and put a link back in, which was a temporary paper clip. and it fired right away on heating which was the same feed for the zone valve for the hot water cylinder as being volt free it didn't matter where it got it's feed from but operated whichever zone valve was calling. , one on a room stat the other on a cylinder stat. No problem firing on hot water from the combi side at all. Both Zone valves were working but neither was operating the internal micro switch. Fitted 2 new 5 wire heads, job done and probably was the problem all along. young kids these day don't understand systems or finding systems faults which is now a fact of life even with their Gas Safe tickets. 2 heads I had in the van £30 each plus 2 hours labour, where the customer had paid out around 10 grand in 3 months with no one finding the fault or even looking for it. Sad the game is down to this, but it is getting more some haven't a clue.
Give it a Fonzarelli tap and it's Happy Days.
Great video and another sharp barnet cut 😀
Great tips my man , hey do you have any tips on oil ? and servicing them ?
Or the 3 o'clock at Cheltenham.....
Looks like you have the Danfoss programmer. Mine went faulty after last week's 5-hour power outage (December 2023). When the power eventually came back on, the Danfoss display screen is blank and both LEDs are on. I tried resetting it with the recessed reset button, but it didn't work. Then I switched off the circuit breaker (in the consumer unit) for the programmer, then switching it back on. That didn't work either. Both LEDs are still on permanently and the display screen is blank. This is not the first time the Danfoss programmer has failed after a power outage. The usual fix is to call the heating engineer who fits a new programmer. I've had three go faulty like this over several years. Any comments from professional plumbers or electricians?
legend. I just tapped the pump with a hammer to get it going. saved me a plumber. thank u
What plunge saw did you use for that hair cut?
He used the Braun with 5mm cut depth 😉
Happy hair cut 👍
Awesome. Tap of the punp and all is good.
Boss man Rodger going to make plumbers tear their hair out. Fair play mate.
Well explained Thankyou
Only a few bolts to spin the pump head round, shouldn't be on the bottom..
My central heating was okay for 20 years until I was persuaded to fit a new boiler.
A bunch of cowboys fitted it and now every winter, it won't start.
Would cost me £150 every winter to get someone out.
I'm going to drain the lot down and get shut of the CH altogether.
I've used electric oil filled radiators for last three years and saved a bloody fortune.
thank you for good tips
Thank you Roger. you’re a legend ❤
Top advice rodge 👍👍👍. An idiot could sort simple problems out if they listen to your advice. Not that any of us are idiots 😉😉
Can you do a video on sizing a boiler
"My heating wont work"
Have you credited your pre-payment meter?
"Oh, does it work on gas?"
I kid you not.
😂
😃"my gas hob stays lit after I've turned the switch on the wall off" amazing tenants
Very helpful guy. Thanks
👍❤🙏，I followed your method and it worked.🙏🙏🙏Big thanks. God bless you
Absolute legend, thank you
Combi boilers are great but unlike an old system, if your not gas safe you can’t do that much to them.
Just like old cars I used to work on, nice and easy but these days I can’t do a lot with them 😅
Have a fight with a lawnmower Rog?
Thank you so much it worked
My 2 rads down stairs are still freezing, the pump is working & the thermostat is working. This is with log burner , but when we put the heating oil on the rads heat up, any help would be grateful
Got to 19 secs . Why would the customers be phoning up to say I've turned my heating off but there's nothing coming through my radiators? Do you not mean turned them on ?
yes, a slip of the brain
my central heating works , buy ONLY when have the hot water switched on ???
There's some very CUTTING remarks about your hair Roger🤣
How to cut hair is coming soon!
It is only hair so I don't care. Those were my very words to the landscape gardener
Good guy. 👍
First thing you should do. But not everyone realize it obvious. Check on on off switch, make sure it's not off.
No, check you're in the right house....
Belt it man!, till it leaks ;
All the green stuff around those pipes, is that normal?
I got a steam furnace, some pipes, especially by the joints, have some green stuff. Also the pipe that comes out of the furnace, drain to the drain spigot, is all green.
I also have a hot water pipe, which is green, and have some white stuff. The white stuff looks like small pieces of popcorn. It on the hot water, and about 5 feet from the water heater. But there's like 2 or 3 t's between this pipe, and those are OK.
But that joint would be easy to fix, it's just screws in.
It's not normal and there are several things that need fixing in this plant room, I think I'll be back somehow.
Dot and dab "when your tiles fail"
How do I make contact with you guys directly?
Any ideas as to why my dads sits at 3bar. Even after bleeding completely it goes right back up
Taken out of context that comment would confuse the heck out of people lol
Hi Roger
I have a cold towel rail in the bathroom and it’s only warm at the bottom. Any ideas ????

Try bleeding your towel rail
Nice haircut Roger
😎
0.16 = “ive turned my htg off, and nothing come to the radiators” that’s fine mate 😅
I've turned the radiator "OFF" but there's NOTHING coming thru the radiator's, YOUR words, NOT mine !!!!!
YES Jerry, we GET your POINT
@@SkillBuilder GLAD to HEAR it roger OLD chap .
I do enjoy YOUR videos roger dearest, they're VERY informative and educational
@@t5jerry Thanks Jerry, we appreciate your support
@@SkillBuilder when you say "we" is 1 referring to the royal "we" , 1 didn't know 1 was related to royalty, perhaps you could answer a long standing question, as one's related to royalty, perhaps 1 could answer wherether the royal "wee" is different to common "we" or does 1think ones taking the "urine" ???? 🤔🤔🤔
Hey Roger, your pump isolator valves are shot 🇬🇧😉
You are not wrong, although it's not my plant room or my installation. Just here to fix things.
Looks like they have got softened water running through that system. Nice way to damage your system. The pump is also installed wrong.water all over the electrical bits.
Interesting comments. Are you a plumber?
I would love to know how you can see softened water inside the pipes. The leak around the pump valves is lime scale which is common in the London area and is the opposite of soft water.
The pump is going in the right direction for the flow. Ideally the pump would be vertical to self vent but there are plenty of instances where a horizontal orientation is permissible. The electrical connections are sealed in a box with rubber gaskets.
Grundfos say : Where pumps can only be installed in horizontal pipework, it is imperative that the pump shaft is horizontal, or slightly higher at the vent plug end. The shaft must not fall below the horizontal plane, even by a few degrees, as this causes premature wear of the top bearing and shaft.
Pumps should not be installed with the shaft in a vertical plane, as this may lead to dry running of the top bearing, noise and possible pump failure.
Skill Builder hiya yea it’s my job. The pump just needs the 4 Bolts undoing and turning around so the electrics are not at the bottom it will still pump the same direction, I know there’s a gasket but it’s not ideal and if you read the manual it’s says not to do it that way.
Lime scale in central heating systems isn’t normally a problem on sealed systems as there’s not a an endless supply of limescale being pumped in if there was a leak or something, it would be evident there’s a leak the pressure will keep dropping and get fixed (hopefully). It tends to be iron oxide a posh word for rust , it doesn’t look like that on the out side of a sealed valve. Iron oxide lines the inside of pumps and pipes etc.
I live in a hard water area and there are lots of softeners around here. For some reason the sodium in the water reacts with the brass fittings in the central heating and looks as it is in the video. It looks like the brass starts flowering and becoming a bit of a mess getting also getting little marks just popping out of the sides of brass fittings where no join is. Worcester bosch boilers for some reason Especially get affected by softeners.
They may not have a softener but it would indicate the water is not neutral with a valve in that state. Would be interesting to see if they have a softener.
Don’t put soft water in your heating it doesn’t do it any good. Thanks for responding.
Ignore what they say about your hair Roger. Those in the know are aware it's only for work.
3 things you should try;
Get in the woods
Build a log cabin
Learn coppicing
Have you read Walden by Henry David Thoreau? Very good book.
Skill Builder No I haven't read that book, I certainly will though thank you for the insight. I'm currently reading a book called Living Water, by Olof Alexandersson - it's an awesome read and also looking into the research of Viktor Schauberger. 👍🏻
@@tanja8907 That looks interesting, I'll add it to my reading list. We could start a Skill Builder book club.
no chance of my heating working, boiler is stuffed, has been for years, somehow i have managed without it. problem is that i have not found anyone that i trust to replace it, everyone wants to charge way too much, over £2500 and they say it will take a day, that is about £800 for the boiler and £1700 for a days labour. is that too much or am i being a tight arse?
I bought my combi boiler for a grand the same model I ad in before so pipework lay out was the same. Could I get a plumber to plum it in no one wanted the job cause they didn't want me to no what a set of greedy bastards they are they want to get boiler and say you after pay for service e every year and charge you 2 and a half grand for boiler and a days work
Just remember that you do not pay just for their time. You pay for their experience, getting it right the first time, doing it safely, leaving it safe and maintaining your safety with the annual services. You will also get an extended warranty period when you use an accredited engineer who pays for the additional training etc.
@@ChristianBHough but I dont agree you should earn as much as a consultant surgeon!
@Stu we all have to pay for going to the job and coming back! We all have to pay for our vehicles but you can claim tax relief on your interest on the finance, car road fund, insurance, repairs, service and MOT, we cant! The time you spend in merchants should be accounted for in your price. Some firms only pay statutory sick pay. You can take out insyrance AND get rax relief on the premium.
Dont think holiday pay is an extra on top of our salary, its not! If I earn 30k a year, its for 52 weeks. If 6 are holidays I still get 30k. I dont get 30k PLUS 6 weeks more, when on holiday. Whatever you earn, when on holiday youre not, "not earning", youre on holiday, the same as us, but you still recieve your income over the year.
Why do the self employed think we get it as some sort of extra?
In addition you'll get use of home as office allowance, depreciation on vehicle, tools etc. We dont. We pay 12% NI on what we earn, you only pay on the profit you make. Not enough profit you pay voluntary toward your pension, which is buttons in comparison. You get money on your scrap.
Then theres the cash jobs and charging for materials already paid for, left overs from other jobs.
We know youre not as hard done to as made out, which is why we object to a grand a day!
@@cliveramsbotty6077 i have replaced all the pipework and radiators ready to go, just need to get boiler replaced, my house is tiny, only 4 rads and 2 sinks.
Do I need a priest for the exorcism?
No you can do it yourself provided you have a handbook on the occult.
