The Costway 25-inch recessed infrared electric fireplace is the most powerful electric heater in this fireplace range, pushing up to 1800W of warmth for rooms up to 37m² (400 sq ft). Power is adjustable from 900W to 1800W, and a thermostat spanning 16°C to 28°C holds your chosen comfort level. On the full 1800W setting it costs around 47p per hour at 26p/kWh, dropping to roughly 23p on 900W and less once the thermostat cycles. As a 100% efficient electric heater, all the electricity it draws becomes heat, making it well suited to warming a main living room quickly. The infrared-style fireplace pairs that heat with 3 flame colours and 4 brightness levels that glow with or without heat, so it works as decoration in any season. The remote controls the flame, heat and a timer of up to 6 hours from 6m away. UKCA certified for indoor use, it runs quietly and includes overheat protection. At 13kg with a 64.25 x 21.64 x 47.75cm footprint, its slightly deeper body houses the larger heating element. In the box: the electric fireplace insert, remote control and instruction manual.
