Creda Heating Solution - Sizing Guide: Commercial Space Heaters; Sunslim Radiant Heaters Sizing Guide; Sunquartz Radiant Heaters Sizing Guide

When planning a radiant heating
installation, refer to Table 1 to select the
application and type of environment
you wish to heat. Table 2 shows the
area that can be heated by a single
Sunslim radiant heater in 3kW and
2kW variants.
Note: Heating areas can be overlapped
to achieve the necessary heating index.

Use the following procedure when
planning a Sunquartz heating
installation for buildings having a floor
area of up to 500m
2
.
• Make a scaled plan of the area to be
heated, noting possible mounting heights
and positions
• Determine the overall heating requirements
WxYxK = Total kW loading
1000
Key:
W= Length to be heated in metres
Y = Width to be heated in metres
K = Intensity watts per m

, determined
from Heating Index Table 1
• Determine the number of Sunquartz
heaters by dividing the kW rating of the
selected units into the total kW loading
from stage 2
