Thank you Allen - think you might have saved me a few quid there. And as a Leeds native living in Glasgow, so great to get the instructions from a Yorkshireman!
Very Helpful. No matter how may times I read the British Gas Help I still wouldn't of twigged the key goes in on the 'unlocked' position as this 'seems' counter intuitive. Watched your video, sorted mine on 5 minutes. Thanks.
Yes! Most definitely! Err on the side of caution! Always! There is a (maybe very slight) possibility of electrocution. Water; electricity, and Humans don't mix. Keep them separate. Leave it switched off for about ten to twenty minutes; so that you get an accurate (room temperature) pressure reading on the pressure gauge when you top-up the water. Go very slowly and don't go too much over 1 - 1.5 bar pressure. There are safety features to prevent electrocution but, when doing any DIY procedure(s); always isolate yourself from any live circuits - i.e. switch it off until you've carried out the procedure(s).
I've got one of these boilers (Which? recommended nine years ago) and it's never worked all that well. If I were to replace it, could you recommend a good make of boiler that is reliable, well made, easy to service and has a simple to use key/valve for re-pressurization? Thanks
Hi Alan, that was really useful thank you. Can I ask, what is the name of the white nozzle on the left? For some reason my boiler hasn't got one. (not the filling key, they other thing)
Should also add that the main reason (apart from refilling/ venting radiators) for system pressure drop is possible leakage from PRV and/or failure of expansion vessel on rear of boiler. Expansion vessel should be checked and re pressurised with annual servicing which will generally prevent problems with PRV failure.
Oh good to know. I have to re fill mine 2 to 4 times a year, every year. I've always had air in the rads or system somewhere and I figured the air was eventually getting to the PRV where the boiler would let it out.
My internal filling key will not turn completely to the right so pressure keeps going down. Can't remove it either. Could a spritz with WD40 help and would it be safe? The key is the original one and was left in the boiler slot at last service. Thanks for your advice.
@@AllenHart999 thanks. After being topped up, and heating on, pressure went to three and half. And after fifteen mins boiler stopped. Few days later when heating is off, the pressure is on two. Same thing happens. It goes high when heating on and after ten fifteen mins switches off. Shall I bleed any heater for air to drop pressure? Many thanks.
Help...my boiler man has left my pressure in the red but reversing your key lock method I cant get it out to bleed water out? Its off at a n angle away from the padlock but I cant pull it out?
On my 24CDI Worcester boiler I do this and there’s a drip from when I take the key out afterwards, the tap takes a lot of strength to turn on and off again, I’ve turned it off right the way but there’s still a drop coming from it every few minutes, if I try to turn it off anymore I think I’m gunna snap it
Why does the dial show green up to 2.5 but you say only pressurise it to 1 ? also another plumber on YT said put it to 1.5 bar, so I find this a little confusing !
@@samlisa3550 Hi, I sorted mine out. Mine was internal, so one of the pipes leading to the boiler may have a valve that you can turn and it will fill the boiler. Hope this helps
Hello Allen. I've got a Worcester Combi-boiler. The pressure gauge is at zero when I just have the hot water on but when I put the central heating on it goes past 2. Why is this?
Roy Carter It’s hard to say without looking at it but it may need a new expansion vessel, Could also just need topping up with air. I would advise on having it serviced 👍
This is because the heated water expands with heat and pressure. The normal pressure reading of 1 bar is when the boiler isn't operating. In use, the pressure gauge will go up, you don't want it going too high (into the higher red measurements) as safety features will kick in and the boiler will cut out (hopefully!?) before any damage is done to the boiler (or you). These are approved safety limits to prevent the boiler from blowing up and scalding. It's like making love to a beautiful woman - Don't rush! Know your limits! Be gentle! 😜
The expansion vessel is knakked. Why? Zilmet purposely made their expansion vessels last only 5-7 tops. Why? Because since the E.U banned all the better boilers for these monoxide and NOx spewing condenser boilers that only last 7-12 tops they needed to keep their sales up! So they made their expansion vessels to match the boiler lifespans.
Or are easily lost? What's the betting that you get the call out to re-pressurise at 12.30 on a Saturday or on a Sunday? When all of the heating spares places are shut? I hate those boilers that have either those crappy little keys or a specific size, shape of removable filling loop specific to the make/model of boiler. They always get lost and carrying a copy for each and every make/model is just infeasible. What is wrong with a standard filling loop assembly with a lever valve and check valve and flexi braided hose oh and a couple of cap offs for both valves just in case (belt n braces)
It's awkward to say the least to remove that key. Again, either the householder will lose it or the attending engineer, likely will not carry one. So much so, it has been rendered redundant. W/B do not make boilers any more with this particular filling/re pressurising method.

There is a (maybe very slight) possibility of electrocution.

I Look after loads of these 24i Juniors and make sure I re pressurise expansion vessels as I know what a B****** the PRV's are to change !! ..LOL
The PRV on this model is awkward to get to, indeed. Good point.
Oh good to know. I have to re fill mine 2 to 4 times a year, every year. I've always had air in the rads or system somewhere and I figured the air was eventually getting to the PRV where the boiler would let it out.

If only one bar required why is the gauge marked in green at two bar
This is because the heated water expands with heat and pressure.
The normal pressure reading of 1 bar is when the boiler isn't operating.
