An ideal heater for both the bedroom and the bathroom.
Product Overview
The Select XLS Mirror Infrared Panel Heater is part of Herschel’s high-performance Select XLS range, designed to deliver energy-efficient infrared warmth with a clean, contemporary look. Unlike traditional heating systems, infrared panels warm people and surfaces directly rather than the air, creating a more even and comfortable temperature with reduced heat loss.
With its reflective mirror surface, this panel is especially well suited to bathrooms and compact spaces, helping maximise wall space without compromising on performance or design.
If you’re new to infrared heating, our Infrared Panel Heaters User Guide explains how radiant heat works, where it performs best, and how to size heaters correctly.

Heating Performance & Efficiency
The Select XLS Mirror uses far infrared technology to gently warm objects, walls, and people directly. This results in faster heat-up times, consistent warmth from floor to ceiling, and no air circulation or dust movement.
Infrared heating is highly efficient, converting almost all electricity into usable heat. For a broader efficiency context, see our Carbon Neutral Heating Guide.
Smart Control & Compatibility
The panel features Herschel SMART-R technology, allowing smart control when paired with compatible XLS thermostats.
Choose from a battery-operated T-BT thermostat for simple installation, or a mains-powered T-MT thermostat with WiFi control via app, Alexa or Google Assistant. These controls enable precise temperature management and zoned heating for improved efficiency.

The heater operates silently with zero light and zero noise, making it ideal for bedrooms and bathrooms.
Bathrooms, Safety & Compliance
The Herschel Select XLS Mirror is suitable for bathroom installation when fitted in accordance with electrical regulations and zone requirements. Infrared heating helps keep walls and surfaces warm and dry, reducing condensation in humid environments.
For placement guidance and sizing advice, see our Bathroom Heaters User Guide.
The heater is fully compliant with Lot 20 energy-saving regulations when used with an XLS thermostat.
Sustainability & Build Quality
Built for long-term performance, the Select XLS Mirror uses durable solid-state components and is designed with sustainability in mind:
- Maintenance-free operation
- Over 95% recyclable at end of life
- Supplied in near-fully recyclable packaging
This makes it a responsible choice for homes and businesses seeking low-carbon heating solutions.
Heating coverage guide: Output assumes a well-insulated room with a ceiling height of approximately 2.4m. Larger spaces or higher ceilings may require additional heating. For tailored advice, contact us.
The Select XLS range also offers an optional extended 5-year warranty, increasing total cover to 10 years for added peace of mind.
Infrared heating can be considered a low-carbon option, especially when paired with smart zoning and renewable electricity. Learn more in our Carbon Neutral Heating Guide.
Planning a Room Upgrade?
Infrared panels can work as a standalone heating solution or alongside electric underfloor heating systems when refurbishing a space.

Frequently Asked Questions
Can I run it on a timer or smart schedule?
Yes. With a compatible XLS thermostat (T-BT or T-MT), you can schedule heating times and run zoned control. See our Thermostats Collection.
Where should I install the mirror heater in a bathroom?
Placement depends on bathroom electrical zones and clearances. Use a qualified electrician and refer to our Bathroom Heaters User Guide for guidance.
