Ceramic heaters
Application
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.
Features
- Built-in protective guard
- Robust aluminium case
- Bracket for wall mounting
- 1m pre-wired cable

Control options
- Wall mounted movement sensor to ensure that heaters are not energised when an area is unoccupied. The device will switch loads of up to 16 amps (3kW 230V). Larger and three phase loads can be controlled via a suitably rated contactor. Ref. WH-402
- Wall mounted switch timer capable of directly switching single phase loads up to 30 amps (6.5kW 230V). Larger and three phase loads can be switched via a suitable contactor. The switch is tamper proof and weatherproof to IP54 making it deal for installation in public areas such as pub gardens. Time delay can be adjusted between 10 and 150 minutes. Ref. TS-1
- Combined dimmer and on/off switch controls loads of up to 13 amps (3kW 230V). This device allows the intensity of a ceramic heater to be manually adjusted to suit prevailing conditions. Ref. VR1
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 output, 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 even coverage.

| Badly insulated/damp | 300 | 300 | 300 |
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.
