Sunslim radiant heaters

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.

Table 1 - Sunslim heating index

0.3	Sunslim - Minimum
	mounting distances	Applications	Heating Index
	(metres)	Offices, canteens,	10-14
	0.5	waiting rooms, entrance
		halls, dressing rooms
0.1
	2.0	Shops, meeting halls,	12-16
2.0		recreation rooms, clubs
		workshops, garages,	14-18
		public buildings
		Warehouses, loading bays,	16-20
		hangars
		Churches	18-20

H = mounting height (determined by on-site requirements)			L = length of the heated area	W = width of the heated area

Sunquartz radiant heaters

Use the following procedure when planning a Sunquartz heating installation for buildings having a floor area of up to 500m2.

•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 m2, 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
