Hi,
If you are laying a laminate over a wet system then the subfloor is probably concrete. If this is the case then you should use a 1.5-2.5mm foam underlay with a plastic DPM sheet included.
Manufacturers will always require a DPM laid between any concrete floor and a wood floor.
With the thin foam underlay you should get heat transference through the floor. If you have a timber subfloor then the pipe work is usually laid in trays under the floorboards or in to specially designed trays that go on top of the floorboard. There is usually another layer of thin board laid over the trays to protect the pipe work. In both of these cases you will be best off with a basic polyfoam underlay and then the laminate over the top of the polyfoam underlay.
