Hi all,

I'm aware this has been discussed in previous threads, most of which I've
read through at length. However, I'm about to take the plunge and get
started so thought I might pass my plans by the group to see if anyone
notices anything alarming in what I'm proposing....!

We currently have a seperate bathroom and toilet, both too small to be
comfortable, and are proposing to knock through to make one big(ish)
bathroom. The dividing wall is non-structural, built on top of the
floorboards, and should be relatively easy to remove (once cistern and
radiator are removed...). Our intention is to tile the floor in the new
bathroom - currently we have carpet on lino (on 1940s newspaper!) on
floorboards. The boards are mostly in good nick, except for where a previous
central heating installer has attacked them. We want to put underfloor
heating in under the tiles to keep our feet warm in winter, and intend to
use the electric cable & mat route with controller mounter outside the
bathroom. In order to make sure the tiles don't lift, we're going to need to
put chipboard flooring and insulation down - but if we put this over the
floorboards, then add the UFH, then the tile adhesive, then the tiles, we're
going to have a floor that's about an inch higher than the hall. So the plan
is to remove the old floorboards, replace with chipboard, then add thermal
tile backer board, then the UFH, then the tiles.

My main concern is that some of the central heating pipework runs under the
floor (the hw tank is in a cupboard in the bathroom) so we're going to be
making any future access to that pipework well nigh impossible. Having just
been at a friends house where a solder joint gave up last week, I'm a bit
nervous about the same happening at some time in the future under our
tiles... I'm pretty much committed to the route I'm going to take, but if
anyone has any suggestions re. providing access to pipes under floors, or
sees anything in the above plan which rings alarm bells, your input will be
much appreciated!

Many thanks

Tom
