The ThermoSphere Flat Glass Panel Heater in white pairs a minimal toughened-glass fascia with a 2-stage heating element that combines convection and radiant heat. Rather than a single fixed output, the TSGFR-2000-W runs at a lower and higher power setting (1000W / 2000W), giving finer control over running cost and room temperature than a single-output heater.
Control is via the touch LED display on the unit, the included remote control, or the ThermoSphere smartphone app over Wi-Fi (iOS and Android). It is supplied with both a wall-mounting kit and aluminium feet for free-standing use where wall mounting isn't practical.

Good to Know
This heater includes an electronic thermostat with LCD/LED touch display, 7-day programmable heating schedule, Eco mode (50% energy use), a Protection mode, and open window detection with optimum start as standard.
Important Safety Information
This heater is supplied with a 1m UK plug cable and must be plugged into a standard socket outlet — it is not designed for hard-wiring into a fused spur. It carries an IP24 protection rating and Class I construction; always confirm the permitted bathroom zone against BS 7671 Section 701 before installing near water, and never connect via an extension lead.
2-Stage Heating Element
The TSGFR-2000-W runs at a lower or higher wattage setting (1000W / 2000W), letting the heater deliver full power for a quick warm-up, then drop to the lower stage to hold temperature more efficiently.
Wi-Fi App, Remote & Touch Display
Control the heater from the ThermoSphere smartphone app over Wi-Fi, the supplied remote control, or the touch LED display built into the glass fascia — the display is hidden from view when the heater is switched off.
Eco and Protection Modes
Eco mode reduces energy use to around 50% for lower-cost background heating, while Protection mode maintains a minimum frost-safe temperature when a room is unoccupied for extended periods.
Wall-Mount or Free-Standing
Supplied with both a wall-mounting kit and aluminium feet for free-standing use, giving flexibility in rooms where wall space is limited or unavailable.
Child Lock & Tip-Over Protection
A child lock prevents accidental changes to the settings, while tip-over protection automatically cuts power if the unit is knocked over when used free-standing.
Ultra-Flat Silent Design
At just 105mm deep, the glass panel sits close to the wall with no moving parts or fan, giving silent operation suited to bedrooms and living spaces.

Can I hard-wire this heater instead of using the plug?
No. This model is supplied as a 1m UK plug cable, Class I appliance designed for a standard socket outlet, not for hard-wiring into a fused spur.
Can this be installed in a bathroom?
It carries an IP24 protection rating, but always confirm the exact permitted zone against BS 7671 Section 701 before installing near a bath, shower or other water source.
What's the difference between the two output stages?
This model runs at either 1000W or 2000W. Use the higher stage for a fast initial warm-up, then the lower stage to maintain temperature more efficiently once the room is warm.
Do I need Wi-Fi to use this heater?
No. Wi-Fi and the ThermoSphere smartphone app are optional extras — the heater can be fully controlled using the on-unit touch display or the supplied remote control without any internet connection.
Can it be used free-standing instead of wall-mounted?
Yes. The unit is supplied with aluminium feet for free-standing use as well as a wall-mounting kit, and includes tip-over protection for safety in free-standing use.
What is the warranty on this heater?
This unit carries a 2-year warranty from Thermogroup Ltd, subject to correct installation in accordance with the ThermoSphere instructions.
