RE: Underfloor heating...

["Hawes,Timothy Edward (GEG)" <haweste@xxxxxxx>]

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.
