Low voltage
Low voltage heating films are also suitable for installation on walls to provide radiant heating. These films can include surface finishes designed to take plaster coatings directly onto the installed film. Due to the low voltage, they are completely electric shock safe when damaged due to nails, screws or when other fittings are put directly through the film. Breaks in the resistive film will affect the power output and metal bridges could cause excessive localised heating due to increased current flow and should not be made across breaks in the film. Breaks in the busbars would also cause functional issues.
