The Herschel Krystal Infrared Panel Heater is a premium microcrystal glass infrared heating panel designed for high-performance, space-saving heating in both commercial and residential environments. Combining advanced COSIX Cell Technology with elegant glass design, Krystal delivers efficient, silent warmth with a strong architectural presence.
If you are new to radiant heating, our Infrared Heating Guide and Infrared Panel Heaters User Guide explain how infrared works, how to size panels correctly, and where they perform best.
Advanced Infrared Heating with COSIX Cell Technology
At the core of the Herschel Krystal is COSIX Cell Technology, a next-generation infrared heating system engineered for fast response times, high radiant efficiency, and long-term reliability.
Unlike traditional electric heaters, COSIX technology ensures heat is delivered evenly across the panel surface, producing comfortable, sun-like warmth that heats people and surfaces directly rather than wasting energy warming the air.
Microcrystal Glass Heater – Design Meets Performance
The Krystal panel is constructed from high-quality microcrystal glass, offering a sleek, contemporary finish that complements modern interiors while delivering outstanding thermal performance. At less than a quarter of the size of many traditional infrared panels — yet with comparable output — Krystal’s key advantages are space-saving design and fast warm-up times.
- Superior Efficiency: COSIX technology is reported to be up to 10% more effective at producing radiant heat than traditional heating solutions. It directs heat specifically at people and surfaces, minimizing wasted energy that often heats the air or the panel casing.
- Rapid Warm-up Times: The technology is designed for fast-acting, on-demand heating, with panels reaching operational temperatures quickly (e.g., within 7–10 minutes).
- Even Heat Distribution: Unlike lower-quality carbon fiber panels that may have "cold spots," COSIX technology ensures a more uniform surface temperature across the entire panel.
- High Performance in Small Form Factor: COSIX enables compact, powerful panels. For instance, the Krystal heater using this technology is less than a quarter of the size of traditional infrared panels while providing similar power outputs (600W/1000W).
Designer Infrared Panel for Modern Spaces
- Smooth glass surface with refined aesthetic
- Ideal for design-led residential and commercial interiors
- Discreet appearance with powerful output
This makes the Krystal a popular choice for designer infrared panels, wellness studios, and modern architectural environments.
Flexible Installation – Wall or Ceiling Mounted
Ceiling Mounted Infrared Panel
The Krystal can be installed as a ceiling mounted infrared panel, making it ideal for:
- Space-saving installations
- Even heat distribution
- Environments where wall space is limited
Wall Mounted Heater Option
When wall-mounted, the panel provides effective directional heat while maintaining a minimal footprint, making it suitable for both compact rooms and open-plan areas.
Suitable for Bathrooms & Humid Environments
With an IP44 rating, the Herschel Krystal is suitable for use in bathrooms and other humid environments when installed in accordance with regulations. The glass surface is easy to clean and moisture-resistant, making it a practical and hygienic heating solution.
For safe heater selection in wet rooms, our Bathroom Heaters User Guide covers sizing, placement and safety zones.
Ideal for Commercial & Residential Use
The Herschel Krystal is designed to perform across a wide range of applications:
- Commercial infrared heating for offices, studios, and retail spaces
- Residential smart heating for modern homes and apartments
- Yoga studio heating where silent radiant warmth is essential
- Space-saving heater for rooms with limited wall space
- Low-maintenance heater for long-term, hassle-free operation
Infrared heating’s ability to create thermal comfort without air movement makes it especially popular in wellness and studio environments.
Energy Efficiency & Smart Control Compatibility
The Krystal infrared panel converts almost all of the electricity it uses into usable heat, making it an eco-friendly heating solution well suited to modern energy-conscious buildings.
When paired with compatible smart controls, it supports:
- Zoned heating
- Reduced energy consumption
- Accurate temperature control
For practical ways to reduce energy use and heat only the spaces you occupy, our Carbon Neutral Heating Guide is a helpful companion read.
Control of the Herschel Krystal infrared panel heater is via hard wiring to one of Herschel’s iQ range of thermostats (purchased separately). Due to its fast warm-up times, Krystal also works exceptionally well with Herschel’s PIR sensor, allowing rooms to remain at lower background temperatures and boost only when occupied.
Please consider your ceiling mounting preference when ordering. Note swivel brackets are supplied; alternative recessed mounting requires additional kits such as the Herschel Krystal white ceiling recess kit.
