Heat from traditional radiators rises, meaning that the hottest part of the room is the ceiling. With an underfloor heating system, the heat moves from the ground upward - which means the parts of the room that are the warmest are the first 1.7m - the area we live in. The gentle radiant heat from underfloor heating doesn't dry air in the same way that radiators do, leaving moister air that is kinder to your lungs and to your furniture.
