3.4 Calculating the Floor Surface Temperature

10 of 40
1. Locate desired output (from Radiant Wizard or other source) on left
vertical axis.
2. Follow to the right until you reach the curve.
3. Then move down to the horizontal axis and read the ∆T between the
room temperature and the floor surface temperature.
4. Add the room temperature and the ∆T to get the floor surface
temperature.
Example:
Output needed: 25 BTU/h/ft
Room temperature: 68°F
Temperature ∆T (from chart): ~ 12°F
Floor surface temperature: 68°F + 12°F = 80°F
The floor surface temperature will be 80°F with 25 BTU/h/ft
68°F room temperature.
This chart shows the relation between room temperature and floor surface
temperature for floor heating systems.
