Under floor heating is in now way a new concept, it was first used by the Romans many, many years ago, but things have progressed considerably since then.
Under floor heating works by pumping warm water from the boiler or other heat source through tubing that is embedded in the floor.  Because the area being heated is large, enough warmth is provided even on the coldest of winter days.
Under floor heating is invisible and maintenance free and because the whole floor area is being heated, there are no cold spots and the room maintains and even temperature.
