what the best way to change a worcester junior greenstar 24i prv

[arran197]

fit a duotec HEA instead no plastic to perforate and flood the place ,no stupid blue lights or weird burner gaskets,prv changed in 3.5 mins if i am flying

Ever done one with a integral filling loop? Pain! Best removing the loop, although some times you need to change the washers then.

Still not as bad as these gstar ijnr though!

Have to do one of these later, cant lift the boiler off. Drat

i have to cut the return to install an expansion vessel so i can pull that out to give me more room.

can i get the clip off and lever the old one out with a thick screwdriver?

in the past ive just lifted em off 🙁

i seriously don't fancy taking the hydroblock out.
its in poor condition as it is.

I normally cut the cold inlet out and then you can do it, should be ok with the return pipe out the way though.

Flue turret off, isolate boiler, undo the 5 nuts , lift boiler up and pull bottom forward whilst top is still on jig. Should be able to remove then, replace 5 fibre washers and refit.

Or

flue turret off, flue out, undo 5 nuts, lift boiler up and completely off the wall. Remove jig. Replace with another boiler. Smash Worcester boiler up into tiny pieces and recycle into something more worthy.

will the flue turret come off if the flue has been cemented in

Yeah it should do as you can slide in inner flue connection from the boiler down back inside case so it finishes flush to the top so the elbow should slide out, if that makes sense?

I actually had a prv and expansion vessel to do on one a month ago and did it in about 45mins, luckily the flue hadn't been cemented in by the idiot that fitted it so I could just take it out and get the vessel out easily and then got my hand up the back of the boiler and did the prv.

Why can't you take the boiler off Killy?

Believe it or not they have mounted it up in a rather high pitched loft so they didn't need flue extensions. No way am i risking taking it down the ladder or resting it on the jig.....

They put the boiler up there when they had a new roof put on, you'd have to cut a bigger loft hatch to get the boiler out or a new one in!!

i can just imagine people driving past with a boiler just mounted up in the middle of no where.

they weren't even in today, they can wait till monday to get any hot water now.

i'll get photos of it

Had to take a prv out a Greenstar 24i System earlier, same as the combi, but a metal plate instead of the phex, the diverter valve blocked off and then the other cold inlet hot outlet plugged off. Because there was no cold feed pipe, it made it much easier to get the prv out. Was still a pain in the backside though. The installer had put the return almost resting against the prv.

Feck replacing it. Cut it and cap off. Remove return valve, fit a 3/4 iron tee. Thread prv in branch and. 3/4 stud in bottom. Put outlet back on stud and connect return at its Lower position. Connect prv to ex pipe. Bye!

In and out in 30 mins. Looks like it should be in a plant room but loads less stress than messing on in cupboard under boiler!
