RE: Underfloor heating...

["Clive Dilley" <clive.dilley@xxxxxxx>]

I used a Danish system from WICKES (it comes in two sizes - 400W &
800W)for
my bathroom and will install in my conservatory (when we get the
tiles).

For the bathroom, I pre-layed Aquapanel (again from Wickes or B&Q)
which is
a concrete covered board that is only about 9mm thick. The instructions
said
this was critical to ensure no movement from the wooden floor below.

Typically with a wet system the pipes are clipped *underneath* the floor
and
aluminium diffusers fitted to spread the heat. You obviously need access
to
underneath the floor to fit this :-)

Also, think carefully about where you'd site the manifold and control
valves
for a wet system. They can be bulky and also get hot (~30-40degC).

In some circumstances electric UFH vendors recommend covering a wooden
floor
with ply (or hardboard I can't actually remember :-(  ) and then
fitting the
mat etc. on top of that. It can reduce movement / flex and help prevent
cracking of the adhesive / grout.

FYI, my bathroom floor was 8'x2', 18mm chipboard sheets.

Cheers,

Tim H.
