Further Info 

Selecting the Correct Sized Heater: Normally the Mirror Demister closest in size, but smaller than the mirror in question should be selected. The area covered will remain condensation free plus an additional margin around the edge of the mirror heater.

Combining Multiple Units: Multiple units can be combined to ensure complete coverage for the mirror in question. When units are combined there must be a 10mm gap between each heater, and they should be wired in parallel.

Coverage: Although a Mirror Demister is usually installed covering the majority of the mirror, there is no requirement for this to be the case and some people prefer the look of a smaller panel in the centre of the mirror to be clear, surrounded by an area of condensation. To obtain this effect, select a mirror heater significantly smaller than your mirror.

Simple Installation: Mirror Demisters have a self-adhesive backing enabling it to be easily attached to the reverse of a mirror. The mirror can then be affixed to the wall and the mirror heater can be covered with mirror adhesive, which must be solvent free. If being used with a safety-backed mirror the backing should be earthed, as should all metal parts surrounding the mirror.

Suitable for Nearly All Mirrors: Glass is a good conductor of heat and Mirror Heat is suitable for all recognised thicknesses of mirror. The thicker the mirror, the longer it will take for the heat to permeate. Care should be taken with mirrors that have cut-outs as the mirror will be weakened in that area. The possibility of weakness will be reduced if the corners of any cut-outs have radii.

Hotel Projects: Mirror Demisters are particularly suitable for use in hotel projects where it can be wired in through either the bathroom lighting system or the key-card operated circuit. Mirror Demisters are specified as standard in most new hotel complexes or refurbishments.

Wiring: Mirror demisters must not be run continuously; they can be wired through the lighting circuit, or to a separate switch if preferred. The circuit must be protected by a 5A fuse or circuit breaker, and the wiring circuit must contain an all pole disconnection. Mirror heaters are not suitable for use with power supplies controlled via a dimmer switch.
