Add the warmth and glow of a real fire with this Costway 23-inch electric fireplace insert, an electric heater that combines genuine heat with year-round ambiance. With two power settings – 750W and 1500W – it heats rooms up to 37m² (400 sq ft), and an adjustable thermostat holds your chosen temperature anywhere from 18°C to 28°C. On the full 1500W setting it costs around 39p per hour at 26p/kWh, and roughly half that on 750W, with the thermostat trimming cost further once the room is warm. Because it's a 100% efficient electric heater, every unit of electricity becomes heat – useful for zone heating a single living room without firing up central heating. The flame effect comes in 3 colours and adjustable brightness levels, and quiet operation means it won't intrude while you read or watch TV. Safety is covered by UKCA certification and built-in overheat protection. A user-friendly remote lets you adjust heat, flame and temperature from the sofa. At just 9kg and 58.4 x 12.9 x 43.4cm, it slots neatly into media units and mantels. In the box: the electric fireplace, remote control and instruction manual.

23” Electric Fireplace 750W/1500W Fireplace Insert — FAQs
How much does the 23" Electric Fireplace cost to run per hour?
On the full 1500W setting it costs around 39p per hour at 26p/kWh, roughly halving to about 20p on the 750W setting, with the thermostat reducing cost further once the room is warm.
What size room does the 23" Electric Fireplace heat?
It heats spaces up to 37m² (400 sq ft), making it suitable as a primary heat source for a typical living room or as zone heating elsewhere.
Is the 23" Electric Fireplace cheap to run compared with central heating?
As a 100% efficient electric heater, it turns all the electricity it draws into heat, so heating one room directly can cost less than running central heating for the whole home.
Can I use the flame effect without the heat?
Yes. The 3 flame colours and brightness levels can be enjoyed for ambiance, and the thermostat and 1500W/750W settings let you add heat only when needed.
What's in the box and is it safe?
You get the fireplace, remote control and instruction manual. It's UKCA certified with overheat protection and an adjustable thermostat from 18°C to 28°C.
