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.
In order to spread warmth throughout a room, these electric fireplaces use a "fan forced heater". Large metal coils are heated within the fireplace, using electricity. A fan is then used to direct heat from the coils outwards, thereby heating the room. These fan forced heaters are silent and very energetic and efficient, allowing the heat to spread over a large area. As soon as an electric fireplace is turned on, the heat is provided instantly with no delay for heating elements to warm up.
