Infrared mirror heating panels
What are mirror panels?
Infrared mirror panels are heating panels with a mirrored front, so they double as a full-length or vanity mirror while warming the room. Because the glass surface stays warm, the mirror resists misting up — which is why they are popular in bathrooms and bedrooms. In a bathroom they must be IP-rated and installed in the correct zone by a qualified electrician.
At a glance
- Best for
- Bathrooms, en-suites, bedrooms and hallways where a mirror is wanted and wall space is limited.
- Mounting
- Wall-mounted at normal mirror height; in bathrooms sited to the correct IP zone.
- Sizing rule of thumb
- Around 80–100 W/m² of floor area; mirror models come in fewer sizes, so pair two for larger rooms.
A heater and a mirror in one
A mirror panel puts the heating element behind a mirrored glass front, so a single fitting does two jobs and takes no extra wall space. In compact bathrooms and en-suites — where there is rarely room for both a mirror and a heater — that dual function is the main appeal.
Because the glass is gently warmed whenever the panel runs, its surface stays above the dew point, so it resists the misting that plagues ordinary bathroom mirrors after a shower.
Safety and IP ratings
Bathrooms are split into electrical zones, and any heater must carry the right IP (ingress protection) rating for its zone and be installed by a qualified electrician. A mirror panel warming the room also helps lift surface temperatures above dew point, which reduces the condensation that feeds bathroom mould.
