The specific distance between the heating cable and the enclosing constructions, appliances and other parts of electrical grid is stipulated by the standard DBN V.2.5-24: 2012. The distance from the wall can be 3 to 10 centimetres. This is necessary to avoid damage to the heater itself when installing skirting boards, etc., and to optimize the useful area of ​​heating, as nobody, unnecessarily, goes right up to the wall.
