Halogen Heaters
SELECTION
Selection of the appropriate loading for Halogen Heater installations
depends on a number of
factors, namely design temperatures, air movement, clothing
and activity of the occupants and
the direction of the beam. These factors are taken into account
by applying the values given in Tables 1 and 2.
- Calculate area to be heated. (A sq. m.).
- Ascertain Power Loading for Type of installation. (P W/sq.m.).
- Select (from Table 2) the appropriate mounting height
to reach halfway across the area. Space out the units on
both sides of the area to be heated, ideally the distance
between units should coincide with the total width of the
beam.
- The number of units (N) is then given by :-
N = |
AxP

Example
A warehouse is to be heated with Halogen Heaters.
Dimenions are 15m x 6m x 4m to the eaves.
- Area to be heated A = 15 x 6 = 90 sq.m.
- From Table 1, Power loading P = 135 W/sq.m.
- Units to be mounted on longest walls. Half way across
area is 3m. Thus from Table 2 suitable mounting height is
2.5m. Total width at 2.5m height is 7.3m thus for best heat
distribution units should not be more than 7.3m apart.
-
Number of units = |
AxP |
= |
90x135 |
= |
8 units. |

1500 |
Taking into account windows, doors etc. mount 8 x 1500 units
at 2.5m high, 4 units evenly spaced down each side of the
building. ie. 3.75m between heaters and 1.875m from the end
walls.
An alternative with fewer units but less even heat distribution
would be 4 x 1503
units at 3.0m high, 2 per side with 5m between heaters and
2.5m from the end
walls.
