I have almost finished the kitchen refurbishment in a property I am
renovating and it will soon be time to have central heating installed
including a new combi boiler in the kitchen.

I would be grateful for any ideas regarding pipe routing for the boiler
before having a heating engineer down to look. See below for details.

Space has been left at the end of the wall unit run for the boiler and
directly above that space I made a large void above a section of recently
lowered ceiling ( needed to be lowered at that place for other reasons so
presented itself as an ideal place for the boiler and piping ) to
accommodate wet piping to the rest of the property. This gives near access
to the notched joists that were used in the previous central heating system
and subsequent access to the rest of the house for piping.
Joist positions in the void would not obstruct piping rising up the wall on
which the boiler will be mounted.

Unfortunately there is no viable option but to receive the gas supply for
the boiler from below despite my dislike of pipes emerging from a kitchen
worktop surface.
The worktop in that place will remain removable until this has been
completed.

Using the combi boiler in our house as an example, I see that pipes usually
emerge from the bottom of the combi as that is where the unions are.

What I want to avoid on the renovation, if possible, is a bigish and
intrusive pipe 'boxing in' situation below and to the right of the boiler
where the wet pipes do an extended U turn and shift to the right ( to avoid
the position where the boiler is actually mounted ) to make their way to the
ceiling and the void.

My thoughts are these

1/. Is it permissible to mount the boiler on, say, 3" x 2" timbers,
correctly spaced for the boiler mountings, fixed vertically to the wall to
allow the wet pipes to pass behind the boiler and thus only needing a small
U turn under the boiler avoiding any wide boxing in of pipes below and to
the right of the boiler. ( Takes a breath ...... ).
Obviously some diversion of pipes would be needed to avoid the flue.
I could extend the 3 x 2 's to the ceiling to box in above the boiler - that
would be OK and look much better than big boxing below.

2/. Do all wall mounted boilers only have pipe terminations at the bottom of
the boiler.
Is there such a thing as 'pipe U turn kit' to address the problem.

The property is a renovation for rental so I'm going to be looking for a
budgetish boiler - not necessarily the lowest price though as eventually it
is for my daughter.

How have you overcome a similar problem?
Just want ideas to offer to the heating engineer.

Thanks - Jd

The WB 28i Greenstar Si, i junior and i System boilers have a boiler
support frame which is fitted before the boiler and contains the five
pipes which leave vertically.

You could also take the gas pipe outside for a short run and bring it
back in just below the boiler.

Er, no: they have a mounting frame which, by some heroically precise
pipe-bending, one might allegedly run the pipes through. The stand-off
frame doesn't actually contain the pipes to make a vertical adaptation.
I've managed to run 15mm hot & cold water pipes through without too much
difficulty, but would baulk at trying to fit 22mm flow and return pipes
into the space as well. Actually ISTR W-B doing a pre-piped vertical piping
assembly for some of their range so you may be able to get something
ready-made.

I would have thought that the Vertical Pre-Piping Assembly 7 716 192 570
would be useful even for professionals if it is not too expensive.

I wish that I had known about it before I fitted mine. I was grateful
for the advice about the charging link which saved a lot of time.

That sounds like the thing. There was a picture of it made up somewhere.

There is a diagram about half way down the page on

http://www.worcester-bosch.co.uk/ins...ior-literature

I am still curious about the cost, if anyone has recently bought one. I
could not find a website which lists the assembly.

Ah, yes - I did have a copy already, just forgot where I'd put it :-)

It does look like a virtuoso bit of pipe bending - not something you'd
want to do by hand an a hurry!

Me neither :-(
