Wood-burning stoves are in demand; they fulfil operators' wishes for cosy warmth and a feel-good ambience. They are popular because logs are available regionally and can often be cut by the operator himself. Logs offer the ecological advantage that they burn CO2-neutrally and thus do not support the greenhouse effect.
The other side of this coin is that stoves with too large a capacity are often installed in installation rooms that cannot accommodate the large nominal heat output. The too-large fireboxes are loaded with a lot of wood in order to obtain a beautiful flame pattern that fills the entire firebox. Consequently, the installation rooms are quickly overheated. Another operator error is that the combustion chambers that are too large are loaded with only a little wood. Because the stove is too large, the small fire is operated with too much excess air. Due to this user behaviour, stoves are not used properly and they cause excessive soot emissions in the process.
The future trend envisages wood-burning stoves for well-insulated dwellings, the nominal heat output of which will be matched to their intended use, thus enabling efficient heating with lower wood consumption. Thanks to the new catalytic converter technology, which is integrated into the fireboxes of the smaller-dimensioned stoves, required emission limits can be achieved even with small firing capacities.
The company LEDA Werk from Leer in Lower Saxony has already developed a stove with a small output and established it on the market. With a product from the catalytic converter manufacturer Blue Fire GmbH, a stove for low and passive houses has been created that provides a precisely fitting heat output while safely complying with the current emission limits and a wonderful flame pattern. This modern stove is equipped as standard with an easy-to-understand electronic heating aid, which shows the stove operator the "correct way to heat with wood" and at the same time safeguards the function of the catalytic converter.
