What temperature does it take for us to feel comfortable?
Do you know that if your feet are at warm and your head is at cool, you will feel perfectly comfortable?
If you look at forced air heat, we are heating our living space from the ceiling down to the floor because warm air rises. This means to get our feet moderately comfortable, the temperature at the ceiling may wind up very high. It takes a significant amount of energy to create and maintain that comfortable temperature at our feet in a forced air system.
With radiant heat, we switch that temperature profile around. The entire floor becomes the radiator. The temperature at the floor level is at that comfortable range while the temperature at our head is lower but still at a very comfortable temperature. The heat radiates up from the floor, warming all the objects in the room. Everything in the room will gain a nice, warm, comfortable feel to it. Even your bare feet propped up on the table will be comfortable from the warmed coffee table surface. The amount of energy required to create and maintain this comfortable temperature at our feet is significantly less than compared to forced air.
What makes Radiant Floor Heating so comfortable?
With Radiant Floor Heating, heat is kept where it is needed – at the floor. This keeps you more comfortable (even at a lower temperature setting) because when your feet are warm, you feel warmer. Also Radiant Floor Heating reduces thermal discomforts due to drafts. The heat distribution in a room is optimal when the temperature is higher at the feet than at the head level.
