Like some contemporary fireplaces, the electric fireplace is also portable, meaning it can be move from one place to another. If you are cold in your room, you can transfer the fireplace in your room or in any desired place. It doesn't demand wide-ranging refashioning to be set up and use.
Aside from keeping the warm air from escaping, the doors act to keep the hearth clean just as a fireplace screen used to do in the olden days. With the doors closed, ashes and embers don't scatter about the room, keeping the carpet or rug clean and scorch-free. The doors also have built in devices that divert air towards the bottom of the fireplace. These vents make the fire burn brighter and easier to light.
