Electric underfloor heating over a suspended floor with floorboards on top
I am trying to work out if this is possible. I would like underfloor heating in the 1st floor bathroom, it's a suspended floor, the room is about 2.5m square. I have seen plenty of information on fitting electric mats under tiles but nothing on fitting it under floorboards unless it's on a concrete floor.
So this is what I'm thinking, insulated board on top of the new 22mm jointed floor panels, then the heating mats. Then either a thin flexible screed and an adhesive for the boards, or is there some way to use tile adhesive to attach the boards over the mats?
Has anyone seen this done before? Any options i haven't thought about?
The best bet would be to ply the floor 1st and then use a heating mat on top of that with an adhesive. Then you can get a tiler to tile straight on top of this heating mat as long as the tiles are suitable. Note. If they are to be used in a wet room the area to be tiles around the plughole/ waste pipe will need to be bedded down to create a fall for water run so this may create an area that isn't suitable for the electric matting. S.B.S carpentry services, hope this helps
