Low profile design

Allows maximum use of wall space

Robust steel construction

Suitable for a rugged industrial environment

Metal sheathed finned heating element

Exceptional element life when compared with open coil elements

Automatically resetting over-temperature protection device covering the entire length of the heating element

The heater will automatically be switched off should the flow of air become obstructed at any point along its length

Centrally positioned longitudinal baffle Encourages convection currents for vastly improved heat transfer.

 

How it Works

BLS 110V low level convector heaters are wall mounted at skirting level.  Fixing is through the pre-punch holes in the heaters steel case.

The BLS is a space heater designed to raise the air temperature within a confined area.

Once energised the metal sheathed heating elements will quickly reach their optimum temperature causing warm air to rise from the aperture above the central baffle plate.  At the same time cooler air will be pulled into the heater through the aperture below the central baffle plate completing the convection cycle and ensuring a quick warm up.

 

Temperature control is by means of a built-in thermostat with a front mounted knob for temperature set-point adjustment.

 

Automatically resetting over-temperature protection device is fitted which covers the entire length of the heating element.  This device will switch off the heater should the air way become obstructed.

Controls

The BLS 110V convector heater is fitted with a built-in thermostat.  Temperature set-point adjustment is by means of a front mounted knob.

No additional temperature control is required.

Selection

The BLS 110V low level convector heater is specifically designed for a 110V 1ph supply.  Please check that this supply is available before selecting this model.

ENQURY FORM

In simple terms the output of the installed BLS 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.

Once the target kW has been estimated, select the minimum quantity of heater required to provide that output. 

Heat Calculator

Stage 1 of 5 » Building dimensions

This calculator is provided as a quick and easy means of estimating heat loss from a building. This is a key step in determining the kW output required from a heating system.

Heat losses to an adjoining room or building are usually lower than to the outside world. To allow the calculator to take this into account we have requested the minimum expected air temperatures of an adjoining room. For a stand-along building just leave this field blank.

Stage 3 of 5 » Construction material

U values (W/m²/°c) are a means of determining how well construction material can contain hear. For example a very well insulated wall will have a much lower U value than an un-insulated wall.

All applicable U Values must be completed (refer to guide for assistance)

Input the areas for inside walls, doors and windows if applicable otherwise leave these fields blank.
