The Fia clay core electric radiator is a UK-designed, Wi-Fi enabled heater built around a high-silica aluminium clay core with heating elements fully embedded inside. Rather than blasting hot air like a convector, the clay core absorbs heat and releases it gradually, giving a balanced mix of radiant and convected warmth that continues after the element has finished drawing power. A slimline 78mm profile keeps the fluted white panel unobtrusive whether it is wall mounted or free-standing on optional feet.
Every radiator pairs with a dedicated Wi-Fi thermostat offering 24/7 scheduling, Amazon Alexa and Google Assistant voice control, geo-location, and room-by-room zoning, plus a child lock and open window detection to avoid wasted heating. Choose from the Standard range for most rooms, the Low Profile range for under windows and conservatories, or the space-saving Tall Vertical range for hallways.

Radiator Warranty
Dry Rooms Only
This radiator carries an IPX0 ingress protection rating and is not suitable for bathrooms or any location with a risk of water splash. Install in dry living spaces such as bedrooms, living rooms, hallways, and offices only.
Two Warranty Periods Apply
The main radiator body and clay heat tablets are covered for 10 years, while the controller and other electronic parts carry a separate 3-year warranty.
High-Silica Clay Core
Heat elements are fully embedded in solid clay tablets, which store warmth and continue releasing it without drawing further power once the set temperature is reached.
0-100% Modulating Control
An advanced PCB smoothly reduces power as the room nears its set point rather than switching fully on or off, improving comfort and cutting energy use.
Wi-Fi Thermostat & Voice Control
The dedicated Fia-Stat thermostat offers 24/7 multi-schedule programming, geo-location, and Amazon Alexa or Google Assistant voice control from the free app.
Zoned, Room-by-Room Heating
Group radiators into zones so different rooms can run their own independent heating schedule based on how they're actually used.
Open Window Detection
The thermostat automatically switches off heating when it identifies a sudden temperature drop from an open window, preventing wasted energy.
Child Lock
A screen lock function secures the controls against accidental changes, useful for children's bedrooms or holiday lets.

Can the Fia radiator be installed in a bathroom?
No. The Fia clay core radiator has an IPX0 ingress protection rating and is not suitable for bathrooms or any room with a risk of water splash. It should be installed in dry living spaces only.
Do I need to buy a separate thermostat?
Each radiator is supplied with its dedicated Fia-Stat Wi-Fi thermostat, which handles 24/7 scheduling, temperature control, geo-location, and voice assistant integration out of the box.
Which range should I choose: Standard, Low Profile, or Tall Vertical?
The Standard range (615mm height) suits most rooms and wall spaces. The Low Profile range (385mm height) is designed to fit under windows or in conservatories where wall height is limited. The Tall Vertical range (1215mm height) is a space-saving option for narrow areas such as hallways.
What is the difference between the two warranty periods?
The main radiator body and clay heat tablets carry a 10-year warranty, while the Fia-Stat controller and other electronic parts are covered for 3 years.
Can the radiator be free-standing instead of wall-mounted?
Yes. Each model can be wall mounted using the supplied fixing system, or used free-standing with optional feet, giving flexibility for rentals or rooms where drilling isn't practical.
