The Unknown Electric Fireplace from BSTSEL brings realistic flame effects to any room without eating up floor space. Its ultra-slim 3.9-inch profile means it fits neatly into a recessed wall cavity, giving a built-in look without major renovation work.
Flame customisation is a real highlight here. Pick from 12 flame colours and 12 LED fuel-bed colours, with a choice of crystal stones or log kits underneath. Five brightness levels and five flame speed settings let you dial in the exact mood you want, whether that's a subtle glow or a lively display.
On the heating side you get 750W energy-saving and 1500W high-heat modes, covering rooms up to 45㎡. A thermostat between 16°C and 28°C, an 8-hour timer and quiet 45dB running make daily use straightforward and comfortable.
The About This Item section on the listing mentions both recessed and wall-mounted installation as options. However the detailed product specification states installation is recessed mounting only. We'd recommend checking with BSTSEL directly before purchase if wall-mounting is a firm requirement, since the listing itself shows conflicting information on this point.
It has two heating modes: 750W for energy-saving warmth and 1500W for higher heat output. BSTSEL states this is enough to heat spaces up to 45 square metres, or around 484 square feet. That's roughly the size of a large living room or open-plan kitchen-diner.
The unit uses LED lighting behind either crystal stones or log kits to create the flame appearance. You get 12 flame colours and 12 fuel-bed colours to choose from, plus 5 brightness levels and 5 flame speed settings. This level of adjustment lets you fine-tune how realistic or stylised the effect looks.
BSTSEL lists the noise level at 45 decibels or below. For comparison that's about the volume of a quiet library or gentle rainfall. It's designed to run in the background without becoming a distraction while watching television or trying to sleep.
It's ETL certified, which means it's been independently tested against recognised safety standards. It also includes overheating protection with an automatic cut-off, so the unit shuts down power if internal temperatures rise beyond safe limits.
Yes. It comes with a remote control so you can adjust flame colour, brightness, heat mode and timer settings from a distance. There's also a touch-sensitive panel on the unit itself if you prefer manual control.
Yes, there's a built-in timer offering settings from 1 to 8 hours. This lets you set the fireplace to switch off automatically, useful for overnight use or if you're likely to forget to turn it off manually.
The package includes the fireplace unit itself, a log kit, a remote control and a manual. BSTSEL also provides a step-by-step installation guide and a video tutorial to help with setup, which is useful given the recessed installation process.
