How do bioethanol fireplaces work?
Bioethanol is an alcohol produced from the fermentation of vegetable matter. As it is produced from vegetation rather than fossil fuels (gas and coal), it produces far lower levels of carbon and so, subject to certain limits, it doesn't need to be used in conjunction with a chimney or flue. The bioethanol fuel has a calorific value and so, depending on the amount being burned, is capable of producing heat. In a manual burner, the vapours produced from the fuel are ignited to produce the flame and, by varying the size of the opening of the burner, more or less heat can be produced. By closing the opening of the burner, the flames are starved of oxygen and are immediately extinguished. In the automatic burners produced by Planika, the vapours are piped through to the burner bar from a separate reservoir within the burner and then ignited by means of an ignition coil. The automatic fires have different settings for flame height to control the amount of heat produced. The bigger automatic fires can be linked into electronic building management systems so are particularly suited to bigger domestic and commercial projects.
