A lot depends on the  level of insulation in the house.  If the house is well insulated  the floor only needs to be  a couple of degrees warmer than the required room temperature so the heat transfer method doesn't have to be very efficient.  Using 100mm spacing should largely compensate for the insulating effect of the timber floor.   

Underfloor heating doesn't heat the air in a room very much so  sometimes the  floor can stay heating  because the room thermostat doesn't think the room is warm enough but because of the warm floor it feels comfortable for occupants.      You can control this by  adjusting time and temperature settings.
