SCHG Ceiling Grid Heater

SCH Ceiling Grid Heater
  • Fan heaters for direct mounting into a 600 x 600 ceiling grid
  • Ideal for heating  shops because the heaters do not occupy valuable wall and floor space
  • Supplied complete with egg-crate grille
  • Optional controller for variable output and fan only settings

For multi-heater installations we recommend SystemX

Ceiling Grid Heater

An SCH fan heater provides simple and reliable heating in a car service reception area

Ceiling Grid Heater

Heater specifically designed for integration into a suspended ceiling grid


Each heater can be controlled by one wall-mounted controller and/or one thermostat

Do not use room thermostat with ‘T’ suffix models as these heaters already have a built-in thermostat with ‘open window detection’ feature.

6kW heaters have a built-in relay meaning that the minimum switching capacity of a suitable thermostat is reduced to 10A

Technical Specification

Colour: Exposed surfaces white RAL9016
Other surfaces zinc plated steel
Finish:   Epoxy polyester powder coating
Construction: 0.9mm steel case
Aluminium air diffuser in brilliant white
Fan Assembly: Tangential fan with low noise aluminium fan blades
Shaded pole high performance motor
Factory lubricated bearings (servicing not required)
Heating Element: High quality nickel-chrome resistance wire supported by ceramic plates and fitted with an automatically resetting over-temperature device
Control (models with built-in thermostat)

Temperature control by factory fitted electronic thermostat with panel front adjustment

Default mode – built-in thermostat switches heat and fan.  This can be changed so thermostat switches heat only with fan running continuously.

The built-in thermostat has an ‘open window detection’ feature

Control (models without built-in thermostat)

Temperature control can be provided by a room thermostat

Can be controlled by CS-7 wall mounted controller for on/off/high heat/low heat and fan only settings.  CS-7 can be used in conjunction with a room thermostat

Installation: Designed to rest in the T-bar of a 600 x 600 suspended ceiling grid
Recommended mounting heights 2.5m to 4m above floor level (see table below)
Guarantee: 1 year

In simple terms the output of the SCH heater or heaters 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.

The next step is to select the output of the heater(s) taking into consideration the height of the suspended ceiling.  Use the following table as a guide.

Model kW Built-in Thermostat Recommended mounting height (m)
SCHG-30 3.0 No 2.4 to 3.0
SCHG-30T 3.0 Yes 2.4 to 3.0
SCHG-45 4.5 No 3.0 to 4.0
SCHG-45T 4.5 Yes 3.0 to 4.0
SCHG-60 6.0 No 2.4 to 3.0

Having established the minimum kW output required and the ouput of the individual heater(s), select the minimum number of heaters needed to meet the kW requirement.
