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.
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.
