    Wet underfloor heating system

    My underfloor heating is set at 21 on the stat but the floor area feels cold to touch. I was expecting to feel a little warmth from it. I have since discovered that my builder has laid a 30sqm pack over a 50sqm area. Is this as bad as it sounds? Thanks in advance
