[6] Ethanol fireplaces are a source of fine and ultrafine particles and have a considerable influence on the quality of the indoor air; ventilation reduces the effect.
Automatic ethanol fireplace flames have no direct user contact with fuel.
Fuel is stored in a reservoir and then heated until the alcohol evaporates into the burner.
If the sensors detect any issues — such as an earth quake, low oxygen or excessively high temperatures — they will extinguish the flame.
Free standing or stand-alone ethanol fireplaces are portable, and can be used in any architectural setting.
