When we say underfloor heating, we usually mean undertile warming, this is because most houses already have a primary heating source - i.e. Central Heating. What most people want is not to be shocked awake in the middle of the night when walking into the Bathroom or Kitchen.
Undertile warming is a gentle low wattage system (low running costs), generally only a couple of degrees warmer than body temperature, because heat rises you will find you turn the radiator down where you have "underfloor heating" fitted.
