[buckley plumb]

your obviously listening and getting good at this game buckley,your turning into a outstanding engineer

not that good mate that baxi 105 e i pm you on got the better of me thought i fixed it but 2 days on and gone again . dont like things beating me and feel like a failure when cant sort some things but hey i am not a manufacturer and dont carry a van of bits to try if all else fails .

 

[buckley plumb]

Lol pal, you mean Gloworm turned off the cold mains boiler isolation valve, to change some bits and got wet through!

no mate first thing he did was isolate cold to check for mixer passing said he had 6 like this in past 3 months .

 

[buckley plumb]

yep totally agree

learning every day - still shy on worcester boilers they are a nightmare to work on.

Getting more common with cheap showers and brassware no doubt!

definatley - had a megaflow that kept loosing its air bubble and dripping on exp relif valve. only found after changing the exp relif and pres reducer and still did the same .

Yep had this also, too many outlets it could have been, so put a 3 bar PRV above mains stopcock so all outlets and showers where balanced, on the megaflo you can do this on install as long as you record where the PRV is fitted etc, if a complete new build obviously everything would go via the PRV's balanced port.

they used to come with a seperate press reducer and cold exp relif but now seem to be combined

Correct pal, no doubt due to cost! Although the new combined valve is supposed to flow 20% more with the same pressure!

Really!? I wonder if that's true?

Depends if you believe in Santa Claus?
The wording on their site has been updated to" new water inlet controls increase flow rates by up 20%"
Maybe they got challenged over their claims? It now appears further down their marketing bullet points too

I live in SE London area.
The hot water to taps is always better. Maybe something to do with the shower valves ?
Ariston have advised to check the water volume passing through but dont know how to do that.
thanks

its going to be sludge in the dv causing your issue did your plumber remove this and clean it?

I have no ideas; I dont think so as he didnt mention it.
Is it something I can try myself?

**** Update to this thread ******

Got someone from this forum to do work on this boiler.
His effort and commitment can't be faulted dealing with my crap heating system and I appreciate he helped me out valiently at short notice.

Work Done:
1. diverter cleaned; water system drained for this;
2. heat sensor swapped out (sorry, forget exact name).

after this hot water stopped completely / heating was erractic (PANIC STATIONS).
Looked like pilot light sensor firing up but not staying on.

Next Day

1. electrics fully checked (passed)
2. New (2nd ) PCB fitted.
This restored heating and hot water but still have to halve cold water pressure to get hot water and then temp only goes to low 40s.

So have heating and limited hot water still.

Bill now over £1000;
Plumber has reccommended a proper service and also suggested enlarging the gas supply rate as it seems to be operating lower than optiumum.
Also maybe replace both shower valves as they could be contributuinbg to poor hot water flow.

So the saga continues and im finding nearest cliff to jump off.

Sorry but I have no sympathy....the answers are in this thread! Turn off the cold water isolation valve to the boiler will take less than 20 secs.........then open any hot tap, IF water continues to run after a short while you have a shower or mixer tap passing........if not you have elimated everything but the boiler and gas supply!

You could have got WB 25 Si combi with a magnaclean fitted with a 7 year parts and labour warranty from a Worcester accredited installer for around £1600.00 you will be there soon, as said from my 1st humble post "r.i.p. it from wall, its too late now you've spunked all the cash you never had!
