Hi all

My daughter moved into a house a while back, which has had the boiler
replaced with one of these new fangled things that sits on the kitchen
wall,
and has about a thousand pipes going up to it. No problem there - seems to
work ok.

She is now looking at replacing the bathroom suite, and good old dad is
going to get roped in to do it. Over the years, I have done much DIY
plumbing on my own houses, and would not normally have any trouble
shutting
off supplies and draining down as required, to disconnect the old bath,
basin etc. However, all of my experience in plumbing, has been on what was
previously the 'conventional' indirectly heated stored hot water systems.
Now as I understand it, these new style boilers heat the water 'on the
fly'
like an electric shower, or an antique geyser ??

So, my question is, what do I need to do to isolate the hot and cold feeds
to the bathroom, and does anything need to be done after connecting up to
the new suite, other than turning back on, whatever has to be turned off
to
do the job ?

I have a "Part 2" question on this, related to my own installation, but
that
can wait until I sort out what I'm doing here ...

TIA

Hi Arfa,

I take it we're talking about a combi here then? As you say they heat
water straight from the mains on the fly. If you turn off the mains
water at the stopcock you will turn off hot and cold so you can
replumb bath, basin and loo quite happily. When you're done just turn
it back on again. I assume you're not planning any work on the
radiators here? That's when it gets a bit more complicated.

Cheers!

Hi Martin

Yes, I guess we are talking combi. It does the hot water and the CH. The
original storage tank has been removed from the airing cupboard, which is in
the bathroom where the new suite is going to go.

I kind of suspected from my admittedly sketchy understanding of these
boilers, that there would be no issue other than shut it off, do the work,
and turn it back on again, but I just wanted to make sure, so I did not
finish up asking what I had done wrong after doing it, to be greeted by lots
of sharp intakes of breath and "You did *what* !!??" s d;~}
