An Easy Guide to Install a Mirror Demister
How to install a Mirror Demister Pad. An easy guide.
Before completing any installation please ensure that the mirror is compatible for use with mirror demister pads. We advise against using demisters on mirrors that feature cut-outs for lights or sockets, as these may compromise the integrity of the mirror.
- To ensure efficient heating, it is recommended to cover a minimum of 70% of the mirror's surface with the demisters.
- To effectively cover larger mirrors, you have the option to combine multiple mirror heater units.
- For optimal results, we suggest maintaining a margin of approximately 50mm from the edge of the heating pad to the edge of the mirror. The minimum margin you should leave is 25mm. We have a calculator to help with selecting the correct demister pad for your mirror.

Installation Steps:
- Position your mirror with the reflective side facing down on a level surface.
- Clean the backside of the mirror to remove any dirt or grease.
- Peel off any safety foil from the backside of the demister.
- Position the Mirror Demister with the adhesive side facing downward onto the desired area on the back of the mirror where you want to prevent condensation. Ensure that there are no air bubbles trapped underneath.
- When using adhesive to attach the mirror, it's important to select a solvent and acrylic-free adhesive and follow the manufacturer's instructions for its application.
- If you plan to secure the mirror using screws, make sure that these screws come with rubber spacers. This design allows only the mirror to make contact with the spacers while allowing for slight movement. Avoid making any additional holes in the mirror, as this could subject it to undue stress and potentially damage it during the heating process.
- If the mirror is going to be fitted inside a frame, the frame should allow for a small amount of movement, and rubber spacers should be used where applicable.
- When installing the mirror within a frame, it's important that the frame design allows for a slight degree of movement. Additionally, consider using rubber spacers where they are relevant to ensure proper installation and prevent any unnecessary stress on the mirror.
- The installation of the mirror should be performed with great care, and the services of a qualified electrician should be used to handle the electrical connection.
- Low Voltage (12V) models installed outside of zone 1 must be supplied using a suitably rated and approved 12V transformer, e.g., a low Voltage lighting transformer. Models installed in zone 1 must be supplied by a SELV isolating transformer, with the source outside zone 1.
- Typically, the Mirror Demister should be connected through a fused spur to the lighting circuit of the room. However, it's important to note that the demister should not be left on for extended periods if it cannot effectively dissipate its heat.
- In situations where the demister will be in continuous use, we strongly recommend installing either a thermostat or a timer switch to prevent overheating and ensure safe operation.
- Just like any other Class II heating device, Mirror Demisters have the potential to induce an electric charge in the metallic foil used in the mirror's construction. If this foil is not grounded, it can result in a capacitance issue where the foil accumulates an electric charge that only dissipates when properly grounded. For installations where there's a risk of contact with the metallic foil within the mirror construction, it's highly advisable to contemplate installing an earth connection to mitigate this concern.
