Advantages of Radiant Cassettes
Radiant cassettes offer several advantages over traditional convection based heating systems.
- High level mounting allows flexible use of space
- Gentle radiant effect means that the experienced temperature is somewhat warmer than the actual air temperature. Operating costs are correspondingly lower
- The temperature gradient is very slight which means that the temperature at floor level is virtually the same as at ceiling level
- Radiant heating systems do not rely on air movement and thus avoid the draughts and noise associated with convection based systems

Black Heat Radiant Cassettes
Application
ESN cassettes are an ideal way of providing space heating in both industrial and commercial buildings. They are generally ceiling mounted but can be suspended from drop-rods or chains. The 0.9kW and 1.2kW models can also be wall mounted using the optional wall mounting bracket. Typical applications include shops, showrooms, sports halls and auditoria.
When an even distribution of heat is required, ensure that the distance between the cassettes is not greater than the distance between the cassettes and floor level. Radiant cassettes are designed to raised the air temperature in a confined space. They are not ideal for use as 'spot' heaters.
Energy saving features
- Gentle radiant effect means that the 'experienced temperature' is a few degrees warmer than the actual air temperature. Operating costs are correspondingly lower.
- The temperature gradient from floor to ceiling is very slight. Typically the air temperature will increase 0.3°C per metre. This figure compares with a typical 2.5°C per metre for fan assisted heaters.
Other features
- 5 year warranty
- High level mounting allows for flexible use of floors and walls
- Brackets for ceiling mounting supplied as standard
- Specially treated aluminium heat emitter
- Robust steel case with white epoxy finish
- Ingress protection to IP44
- A radiant heating system does not rely on air movement and thus avoids the noise and draughts associated with fan assisted systems.

A Typical ESN Heating Scheme
6 x 3.6kW cassettes are suspended at 6m above floor level. Note that the distance between the cassettes is less than the distance between the cassettes and the floor. This ensures even heat distribution.
Control options
- HARD CASE controls - ENERGY SAVING, robust, tamper-proof thermostats. Ideal for industrial and public area applications. Ref. HC
- Contactors for switching larger single phase and three phase leads. Ref. CON
- Programmable timer with optional push button for temporary boost. Ref. TIM
Other options
- Wall mounting bracket for 0.9 and 1.2kW models. The brackets allow the heaters to be angled at 45°. Ref. ESN-WB
