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.
Fireplace blowers help to heat your home by forcing the warm air from the fireplace around the room. This should help many people keep their heating costs down during the cold months. There are different styles of blowers available. Some are designed to be attached to your fireplace, while others are meant to sit in a doorway and blow the warm air throughout the home.
