I’ve fitted a few 111w and they are very good storage combis.
Only need 15mm cold in and 15mm DHW out. The flue is not central and is offset to the left so bare that in mind for flue termination.
Only problem with Viessmann’s is the crunchy rubber hose so system needs to be really clean...
Hey Tom,
Why don’t you look at the Baxi 228 or 428 (2 or 5 year warranty). Get them from Williams and Co. Cheap price, easy to install and decent boiler.
Same as me Jay, never stop learning.
Try ringing CIPHE tech like I did, they will provide a definite answer and they deal with cases like this in court as they are expert plumbing witness’s, if you want I can post up their telephone number?
They can also explain better than I can on a keyboard :D
I think your having trouble interpreting the regs Shaun, so you just carry on as you are. If you need clarification from people more intelligent than me and who can explain better than me then please ring CIPHE tech for assistance ;)
Tried to help by doing some proper research so I hope it can...

With building control I have to disagree with you, the...
Hi Guys,
Update for anyone that is still interested, or has the will to live!
I’ve spoke to one of the tech advisers at the CIPHE and he’s said G3 regs only cover the potable water discharges into D1 & D2, and not the discharges from central heating. Therefore you shouldn’t combine them.
I...
Check valves do fail Jay and let by.
I know that the set-up you have done will be fine, but i was just querying whether it was done to standard, as when I did my first G3 it was a no-no.
As said I will look up info or speak to CIPHE and post back.
Happy to be proved wrong :)
That’s why I said Hypothetical, worst case etc :D
Imagine if it was blocked, can you see what i’m trying to say about backflow, x-contamination etc?
Remember the water regs about disconnecting filling loops after topping up systems to prevent backflow.
Which i’m sure we all disconnect ;)
