Make a statement with this wide Costway 36-inch electric fireplace insert, an electric heater whose broad flame display fills a feature wall while warming rooms up to 37m² (400 sq ft). Two heat settings – 750W and 1500W – cover everyday warmth, with a thermostat adjustable from 18°C to 28°C and an 8-hour timer for hands-off control. On the full 1500W setting it costs around 39p per hour at 26p/kWh, halving to roughly 20p on 750W and less once the thermostat cycles, so zone heating one room stays affordable. As a 100% efficient electric heater, every watt becomes heat. The flame effect spans 3 colours and 5 brightness levels and can run without heat for year-round display, controlled via the remote (flame, heat, temperature and timer) from up to 6m away. At 91.44 x 14.47 x 53.34cm and 15kg, it's built to fit openings of 81.8 x 15 x 50cm, with 30cm clearance recommended below a wall-mounted TV. The metal and tempered-glass construction looks premium in a media wall. UKCA certified with overheat protection. In the box: the electric fireplace insert, remote control and instruction manual.
