The cables can be applied in many a different ways:
Bed of sand with a surface covering of for example concrete slabs or asphalt.
On concrete which is then provided of for example covering of asphalt.
In concrete, when the construction is out of concrete and is cast in one step, the heating cables are applied in the concrete by lashing the cable in the upper part of the armouring.
Power required: Depending on the geographical position of the application and the construction of the building the power required could vary between 200 – 400 Watt/m². There are some things you have to think of when deciding the power required, for example how fast the melting off is going to start, to what extent the surface is exposed to falling snow and cold and if vast quantities of snow are coming down from the adjacent areas.
In the previous chapters we have described the design and the installation of heating cables in beds of sand and in asphalt. What now remains is to describe how to apply heating cables on concrete.
