An electric fireplace runs on electricity, which is less expensive as compared to fuel and gas both. The heat is adjustable and can be set accordingly. This benefit was never available in traditional style as there was little control over how the fire looks. The fireplace is not heated up after usage, which reduces the chances of getting burnt accidentally. Especially with small children and pets, this is a significant advantage.
A fireplace glass door is installed on a fireplace to keep the room warm longer when the flames die down. Whether a wood burning fireplace or a gas burning fireplace, heat radiated into the room escapes through the chimney. One does not notice this while the fire is burning brightly, because of the heat from the flames that radiates into the room. However, when the fire starts to die down, the hearth becomes cold quickly as the heat escapes through the fireplace opening. To stop this from happening, a fireplace glass doors blocks the opening, keeping the warm air from leaving the room.
