RP Radiant Ceiling Panel

RP Radiant Ceiling Panel

  • RP radiant ceiling panels provide an economic means of heating a commercial space without producing noise or draughts
  • Typical applications include care homes, offices and meeting rooms
  • High mounting position means that it is impossible for people to accidently come into contact with the source of heat.  For this reason RP radiant ceiling panels are an ideal heating system for care homes.
  • RP radiant ceiling panels are designed to fit snuggly into a suspended ceiling grid but can just as easily be fitted to a conventional ceiling using the low-profile bracket supplied

Features & Benefits

Energy Saving Features

RP radiant ceiling panels provide an extremely economic means  of heating commercial spaces.  Savings of up to 30% can be made when compared to conventional convection based heating systems.

Feature Benefit

No significant 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 ceiling panels is 0.3°C.  Therefore in a 3m high office, the air temperature at high level would be more than 6°C lower when using energy saving radiant ceiling panels.

Radiant effect

In a building heated with energy saving radiant ceiling panels the experienced temperature can be as much as 4°C warmer than the actual air temperature.  This means that the thermostat can set up to 4°C lower than with a conventional heating system whilst still maintaining a comfortable temperature.

Quick Warm Up

RP radiant ceiling panels will warm a space considerably more quickly than a conventional heating system.  It is therefore possible to reduce the warm up period to an absolute minimum.

Other features

Feature Benefit

Choice of Mounting Options

RP radiant ceiling panels are designed to fit into 600 x 600 or 1200 x 600 suspended ceiling grids or to be fixed to a conventional ceiling using the brackets provided.  It is therefore possible to install RP radiant ceiling panels in virtually any room.

Factory installed Insulation

The RP radiant ceiling panel’s robust steel case is packed with insulation material to prevent heat loss through the top of the panel.   This feature ensures that virtually all the panel’s output is directed downwards.

High Mounting Position

RP radiant ceiling panels are ideally mounted at heights between 2.4m and 3.5m leaving wall and floor space completely free and not interfering with activities.  It also means that casual access to the heaters is impossible, an important consideration in schools, care homes and public areas.

No moving parts

Apart from periodic cleaning, an RP radiant ceiling panel is maintenance free and is designed to provide trouble-free service for many years.

Silent and draught free

RP radiant ceiling panels do not give rise to any air movement whatsoever and are totally silent.  These features make the radiant ceiling panels particularly suited to meeting rooms and day rooms in care homes

Unobtrusive appearance

Whether installed in a suspended ceiling grid or onto a conventional ceiling, RP radiant ceiling panels provide an almost invisible source of gentle radiant heat.

 

How it Works

RP radiant ceiling panels are designed to heat commercial premises such as care homes and offices and schools.

RP radiant ceiling panels are designed to fit into 600 x 600 or 1200 x 600 suspended ceiling grids or to be fixed to a conventional ceiling using the brackets provided. They are generally arranged in a grid formation to give good area coverage.  Once switched on, the Energy Saving Radiant Panels emit long wave radiant energy which is the quickest means of heating a space. 

RP radiant ceiling panels offer an extremely economic means of heating a commercial space. Savings of up to 30% can be made when compared to conventional convection based heating systems.  There are two reasons for this.

  1. Temperature Gradient.  When using fan heaters to heat a large space a typically temperature gradient of 2.5°C per metre would be expected.  The equivalent figure for a building heated with energy saving radiant ceiling panels is 0.3°C
  2. Radiant effect.  In a building heated with energy saving radiant ceiling panels, the experienced temperature can be as much as 4°C warmer than the actual air temperature.  This means that the thermostat can set up to 4°C lower than with a conventional heating system whilst still maintaining a comfortable temperature.

Control concepts

Detailed control options are detailed elsewhere however we would like to stress that ESP radiant cassettes should always be thermostatically controlled.  These are the most commonly used methods of control.

Wall mounted thermostat.  Depending on the application select a standard commercial grade thermostat or a robust industrial grade thermostat for public areas.  A thermostat with a set-back facility will allow the heating system to provide frost protection as well as comfort heating.

Timer control.  A programmable timer used in conjunction with thermostatic control can significantly improve economy.  The timer can be used either to switch between ‘on’ and ‘off’ or ‘set-back’ and ‘comfort’ depending on the thermostat selected. 

Controls

RP radiant ceiling panels should generally be thermostatically controlled.  Normally the thermostat will be wall-mounted at approximately 1.5m above floor level.  Where the combined installed load exceeds the switching capacity of the thermostat, a suitably rated contactor will be required.

Here is a summary of the most common control components.

Adjustable wall-mounted thermostat (commercial grade)

RST-IN Commercial Room Thermostat

RST-IN

Model: RST-IN

RST-IN, BN Thermic’s standard, commercial grade thermostats provide accurate control and allow easy adjustment of temperature set-point. 

RST-IN:  +5°C to +30°C

 

Tamperproof wall-mounted thermostat (commercial grade)

RST-TP Tamperproof Thermostat

RST-TP

Model: RST-TP

To prevent wilful or casual adjustment of temperature set point, we recommend the RST-TP tamperproof thermostat.  The set-point adjustment knob is concealed under the thermostat’s cover and optional ‘shear-off’ fixing screws are provided for complete security.

Model: HC-ST2

A Hard Case thermostat is available with all the features of the standard model but with two set-points: high (comfort) and low (set-back).  Typically this device would be used to provide comfort heating when a building is occupied and frost protection at other times.  There are two means of switching between comfort and set-back.

 

Operation Mode One

Use the side mounted button to activate the built-in, programmable timer.  The Hard Case thermostat will then control at the ‘comfort’ set-point until the pre-programmed time period has elapsed at which point it will revert to the default ‘set-back’ temperature.

Operation Mode Two

Use a remote timer (see below) to switch between ‘comfort’ and ‘set-back’ to match the building’s pattern of use.

Selection

If you would like the experts at BN Thermic to select a suitable heating for your application, please click here to access our enquiry form.  Simply provide as much information as you have available and we will respond with a detailed proposal.

ENQUIRY FORM

For maximum economy and performance your selection needs to meet two requirements:

  1. Sufficient kW output
  2. Correct panel distribution

Estimating kW Output

In simple terms the output of the installed RP ceiling panels 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

HEAT CALCULATOR

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 Panel Distribution

Having established the minimum kW requirement, select the minimum number of panels (from the following list) whilst ensuring that the distance between individual panels does not exceed the distance between the panels and the floor.  When installing the panels into a suspended ceiling the choice of model will be dictated by the dimensions of the ceiling grid.

Model kW Dimensions

RP-06  0.6 1200 x 600

 

Radiant ceiling panels, ceiling mounted so that the distance between the panels (dimensions A+B) is no greater than the distance between the panels and the floor (dimension C).
