|Model||kW||Volts||Built-in Thermostat||List Price|
SMH’s low profile design is only 152mm in height making them very unobtrusive
SMH heaters free up wall space and area ideal for shops with solid ceilings
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.

|Thermostat||Mechanical thermostat – tamperproof 20A||RST-TP||£104.00|
|Timer||Programmable 7-day timer 13A||PROTIM-7||£155.00|
A contactor can be used to enable a thermostat or timer to switch a load larger than its switching capacity.
|Finish:||Epoxy polyester powder coating|
|Construction:||0.9mm steel case|
|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.
Can be controlled by CS-7 wall mounted controller for on/off/high heat/low heat and fan only settings
The built-in thermostat has an ‘open window detection’ feature
|Control (models without built-in 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||Keyhole screw fixing to conventional ceiling or suspension from drop rods (4 x M6 threaded holes provided)
Recommended mounting heights 2.4m to 4m above floor level (see table below)

In simple terms the output of the SMH 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
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.
Having established the minimum kW output, select the minimum number of heaters needed to meet this requirement.

|SHM-45(T)||4.5||230||3.0 to 4.0|
