Modern fireplace is known for its energy-efficiency. They use a recyclable and environmental-friendly fuel usually from wood scraps compressed using pressure and biomass gasses. They burn clean also therefore helping in the improvement of the quality of air. They produce less volume of ash decreasing the amount of waste. In addition, they can be operated easily by pressing a button or the thermostat, a device used for controlling and regulating the temperature of a system. Moreover, this model occupies less space compared to other fireplace technologies. It also uses ventilation which is less expensive than that of the chimneys.
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.
