Comfort is the prime factor.
The human body uses the feet and head to dispose of excess heat. Because of this, warming the floor is not only physically pleasing, but the room will feel warmer than it actually is, allowing for lower temperature settings and fuel conservation. The downside to radiant for fuel conservation is slow recovery. With lower water temperatures in the tubing, setting the thermostat back at night or when the house is vacant for short periods is not possible, unless one wants to live with the discomfort while the temperature slowly rises. Radiant heat can be installed in the ceiling when no alternatives are available, but the comfort factor and efficiency are compromised.
