Ceramic heaters emit medium wave radiant energy that passes through the air with minimal losses and is converted to warmth when absorbed by a solid body. They deliver 100% of their output almost instantly and are widely used in applications where the light output of a halogen heater is not acceptable. These include community halls, zoos, kennels, and warehouses. They are best suited to buildings with relatively low ceilings.

Heat Requirements
Use Table 1 to determine the total kW output required. The W/m² applicable to the type of activity and the nature of the building should be multiplied by the total area in m². The 'spot heating' figure should be used when heating a section of an otherwise unheated building.
The ouput, position and mounting height of the heaters can be determined using Table 2. We suggest that the areas covered by individual heaters are allowed to overlap by 10% to 15% to ensure coverage.
Spot Heating
As an additional guide to spot heating, we would also recommend heating from two directions, to cover the area from opposite sides. This will ensure an overall feeling of comfort and warmth. A heat loading of 250-300 W/m² can be considered as a guide for this type of area.
