Compact and keenly priced, this Costway 20-inch recessed electric fireplace is an electric heater that brings flame-effect cosiness to smaller living spaces. Two power settings – 750W and 1500W – heat rooms up to 37m² (400 sq ft), and it runs quietly so it won't distract while you watch TV or read. On 1500W it costs around 39p per hour at 26p/kWh, falling to roughly 20p on 750W; as a 100% efficient electric heater it's a sensible way to zone-heat one room without running central heating. Choose from 3 flame colours and 5 brightness levels, all of which can run without heat, so the fireplace doubles as decoration through the warmer months. A generous 9-hour timer is the longest in this fireplace range, and the included remote adjusts temperature, flame settings and the timer from up to 6m away. The smokeless recessed design slots neatly into walls and media units, and at just 8kg with a 50.46 x 14.1 x 45.79cm footprint it's easy to fit. UKCA certified with built-in overheat protection for safe everyday use. In the box: the electric fireplace insert, remote control and instruction manual.
