Mirror defoggers are a low cost luxurious edition to a new build bathroom or renovation project. They are ideal for hotel developments or projects with multiple bathrooms. Mirror defoggers or demisters should be controlled by a switch, they can be wired through the lighting circuit to only heat when the bathroom is in use and clear all condensation from showers or baths.

Mirror demisters in various sizes

 

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.

Bespoke mirror heaters

Bespoke units can be manufactured to order as required. Alternative requirements for panel sizes, lengths of coldtail or voltages can be easily accommodated.
