I'm extending my kitchen into both my dining room and the hall and
want to tileand ptentially underfloor heat the kitchen floor.
The current kitchen floor is suspended wood, but the kitchen is 2"
strips of wood whereas the other rooms are 5" planed floor boards.
My original plan was to replace the kitchen boards with new floor
boards teh same as the rest of the house, but i've been reading you
have to ply on top of floor boards to tile.
Can i replace the current floorboards with one or more layers of ply
and then underfloor heat and tile striaght to that? If possible it
would mean i don't raise the level of the floor too much compared
with the adjoining rooms.
