Advice on external expansion vessel.

Very dangerous game to presume the system is the same as when it was installed, and was it installed / sized properly in the 1st place ????

and then again has our intrepid Diyer fitted. New loft conversion/ under floor heating in his Wickes conservatory ???

Maybe we will never know

carry on then,after all its not like i have been doing this for 5 minutes

I wasn't having a pop Gasman, but dodgy to presume.
The install, I was working on this week had Artex on the ceilings, big lounge.
The client didn't want overboarding so the ceiling was pva'd twice, a coat of bonding and two sets of multifinish both had pva before each coat.
I was hanging a rad and left the room to get some fittings, all of a sudden 100 kg of plaster fell down, if a small child was underneath it ??


It turns out the Artex was pasted on top of wallpaper, the extra weight of the plaster ripped the paper off!

based on what the op said in post 1,its presumed its the standard set up unless they say differently based on this a 12L would work fine

Based on what customers tell me they get an awful draft through their air vent, so I don't need to check it then ??

Presuming and believing what people say is ???

i dont have a crystal ball,i have not seen it,its based on the op,s first post,if he gets it wrong,negates to tell us the size of the system and undersizes it thats his bad not mine,i based sticking a 12L because this boiler would have has a 10L originally yes it could be different to what they say but frankly as i am not doing the job,and have not seen it i dont care
