Controls
Typically, primary comfort heat control is provided by a wall-mounted programmable thermostat. Depending on the quantity and type of cassettes installed and the voltage supply, the thermostat can switch a group of heaters directly or via a suitably rated contactor. For larger installations see our PC radiant heater control box. (The control box is designed to make multi-heater installs quicker and easier with all heaters controlled from a single point)

How it Works
ESP Radiant Cassettes are designed to heat commercial and industrial spaces and are especially suited to buildings with high ceilings such as sports halls.
The cassettes are generally ceiling-mounted or suspended at a high level in a grid formation to give good area coverage. Alternatively, they can be wall-mounted using the optional wall bracket. Once switched on, the radiant cassettes emit long-wave radiant energy providing the quickest means of heating a space.
ESP radiant cassettes are the most economical means of heating larger spaces. Savings of up to 30% can be made when compared to conventional convection-based heating systems. There are two reasons for this:
- Temperature Gradient. When using fan heaters to heat a large space a typical temperature gradient of 2.5°C per metre would be expected. The equivalent figure for a building heated with energy-saving radiant cassettes is 0.3°C. Therefore in a 5m sports hall, the air temperature at a high level would be almost 15°C lower when using energy-saving radiant cassettes.
- Radiant effect. In a building heated with energy-saving Radiant Panels, the experienced temperature can be as much as 4°C warmer than the actual air temperature. This means that the thermostat can be set up to 4°C lower than with a conventional heating system whilst still maintaining a comfortable temperature.
Selection
If you would like the experts at BN Thermic to select a suitable heating for your application, please click below to access our enquiry form. Simply provide as much information as you have available and we will respond with a detailed proposal.
For maximum economy and performance, your selection needs to meet two requirements:
- Sufficient kW output
- Correct cassette distribution
Estimating kW Output
In simple terms, the output of the installed ESP radiant cassettes must be greater than the heat losses from the building during periods of cold weather. A small amount of heat is lost through the walls, ceilings and floors with more significant losses through windows and doors.
To estimate the heat loss from your building you may like to use our heat calculation tool
The estimated heat loss figure is the absolute minimum kW output that you should consider installing. We would suggest adding approximately 50% to this figure to allow for an acceptable warm-up time in cold conditions as well as making allowances for exceptional weather conditions and possible errors in the original data used in the estimate.
Correct Cassette Distribution
ESP radiant cassettes can be ceiling-mounted or suspended at a high level. For the lowest capital cost, we suggest using the highest practical mounting height, whilst using the minimum possible number of radiant panels needed to achieve the estimated kW requirement. Ensure that the distance between individual cassettes does not exceed the distance between the cassettes and the floor.
