Of course, like all real flames, biofireplace burners give off real heat! Normally, a liter of bioethanol develops approximately 3 to 4 kW/h depending on the type of burner, from the moment of combustion. Furthermore, a bioethanol fireplace is 100% efficient because there is no heat loss through the flue and all the heat produced remains in the room. How much surface area do bioethanol fireplaces heat? On average, bioethanol fireplaces can distribute heat over an area of approximately 20-30 square meters, depending on the burner capacity and flame intensity. However, it should be noted that bioethanol fireplaces should not be considered the sole source of heating in a home: they are first and foremost a decorative accessory that, by emitting a live flame, also heats the room, in addition to creating a pleasant atmosphere. How much energy do bioethanol fireplaces consume? Bioethanol fireplace consumption figures are approximate, as they depend on the model, the burner capacity, and the flame power (which is adjustable in many models). On average, 1 liter of bioethanol burns for 1 to 3 hours. Is a permit required to use a bioethanol fireplace? No. Like all free-standing fireplaces, it is not subject to any legislation, nor does it require special permits. Do bioethanol fireplaces require a flue? Our bioethanol fireplaces do not require a flue because the combustion of bioethanol does not produce toxic substances, odors, or fumes, which must be vented through the flue. Are bioethanol fireplaces freestanding? They are portable pieces of furniture that can be moved when moving; they do not require fixed connections for either power or exhaust since they do not have a flue. How do you clean a biofireplace? Biofireplaces do not require cleaning of ash, soot, etc. They can be cleaned like any other furniture. Do bioethanol fireplaces require maintenance? Bioethanol fireplaces require no maintenance as there are no valves, fans, or other moving parts that can wear out over time. Please note: Decorative stones or wood may only be placed in the fireplace when the flame is out.
