Installation
The mounting position and spacing of these units will de-
pend on the mounting height and reference should be
made to the technical data to determine the optimum
position. The minimum recommended mounting heights
are as follows:
HE7915
(1.5 kW)
2.5 metres
HE7920
(2.0 kW)
2.7 metres
HE7930
(3.0 kW)
3.0 metres
HE7945
(4.5 kW)
3.3 metres
For wall mounting, a bracket arrangement is supplied as
standard and this is shown in figure 1. With the unit wall
mounted, it is essential that the radiant energy is directed
away from the wall. The minimum clearances from the
ceiling or the adjacent walls are shown in figure 2. For
maximum heating effect on the occupants of the room,
the angle of the front face of the unit to the horizontal
should be about 45
0
.
As well as an efficient conversion of electrical energy into
radiant heat energy, the effectiveness of radiant heaters
depends on efficient absorption of this energy by the
people in the building. Heaters mounted overhead, with
their beams directed straight down, will tend to warm only
shoulders and tops of heads. More efficient absorption is
obtained if the radiant heat is directed from one or both
sides of the person. In any situation, the optimum angle
for the heaters will be with the plane of the reflectors at
about 45
0
to the horizontal. Heating schemes should be
designed such that the area to be heated is effectively
covered by units which are mounted close to this angle.
Control
In control systems, heaters may be switched on and off,
using suitable contactors, linked to the time switches or
thermostats. Temperature control using either air thermo-
stats or black bulb thermometers is possible, but the char-
acteristics of radiant heating make it difficult to achieve
comfort control without very careful choice of the ther-
mostat and its position. Details of suitable circuits and ad-
vice on the correct siting may be obtained from Claudg-
en.
With the HE7945 (4.5 kW) unit, the three lamps are con-
nected to three separate terminals. If the links are re-
moved, as for three phase operation, it is possible to con-
nect these units for up to three levels of radiant heat out-
put.
Details of suitable circuits may be obtained from Claudg-
en.
