How a flueless fire works
Most people, when they think of a beautiful crackling fire, think of a fireplace that uses wood as fuel – in other words, a traditional wood fire. The flue gases and excess heat produced are fed outside and into the air via a chimney or flue.
In contrast to a traditional wood-burning fireplace, a flueless fireplace does not burn wood, but rather pure denatured bioethanol, i.e. pure alcohol. No smoke, soot or ash is produced by bioethanol during the combustion process, unlike wood. Put simply, when burned bioethanol produces carbon dioxide (CO2) and water vapour (H2O) in similar amounts to those present in air exhaled by an adult. For that reason, no chimney, flue or additional ventilation is necessary.
The heat produced goes straight into the room that the fireplace is in. Vauni fireplaces have a maximum heat output of 2-3 kW. The heat is immediate and directed and can thus serve as a complement to existing heating systems. Most people usually find that a Vauni produces just the right amount of heat for normal comfort heating.
When you choose a bioethanol fireplace from Vauni, you are choosing modern comfort heating technology. The energy supplied goes straight into the room in the form of heat, instead of being lost up the chimney. This makes the fireplace highly efficient and so you only consume the energy you actually need. As the bioethanol fuel is produced from renewable sources, in net terms no CO2 is added to the atmosphere.
