SWD heaters are suitable for maintaining background heat or comfort heat in industrial buildings including damp and corrosive environments.  The heaters operate by natural convection and are therefore not well suited to buildings with a high roof.

In simple terms the output of the SWD 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 loss 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.

Having established the minimum kW output required, select the minimum number of heaters needed to meet the kW requirement.

The use of SWG safety guards is always recommended where personnel can access the heaters.
