Coverage for Spot Heating Applications
The area heated by a Quartz Halogen Heater depends on the height and the angle at
which the heater is mounted.
For 30° Heater Mounting Angle:
Area Covered = (Height)² x 2.66
Average Width of Beam = Height x 2.0
Throw of Beam = Height x 1.33
For 45° Heater Mounting Angle:
Area Covered = (Height)² x 5.72
Average Width of Beam = Height x 2.2
Throw of Beam = Height x 2.6

NOTE: 1. Intensity is average intensity in W/m² based on Wattage of heater and
area covered and measured on a horizontal plane 1m above the floor level.
2. Heater mounting heights are in metres and are above floor level. Those
marked '*' are minimum mounting heights for the particular heater model.
3. Throw and spread figures are in metres.
