The Atherton is a stylish traditional inset electric fire featuring the innovative Optimyst smoke and flame effects and comes with a coal effect fuel bed, hidden controls, all to create a one of the most realistic electric inset fires available.

Featuring thermostatic controls which mean you can set your fire to produce heat when the room drops to a certain temperature, helping to maintain comfort in your home. The Optimyst technology is fully variable, so you can adjust to create the right level of flame effect you desire and you can even have the flames independent of the separate fan heater to create a year round glow.
