Abstract Biomass combustion systems contribute to the use of renewables, whereby wood log stoves have a high share for domestic heating. Promotion of renewables and efforts for lower air pollution require an improvement of technology. Short‐term effects can be achieved with the help of various retrofit systems. Apart from a survey of available systems, two measurements have been analyzed: additional heat exchange and emission reduction by catalysis. During normal operation of three low‐cost stoves, high levels of carbon monoxide (CO), volatile organic compounds (VOCs), and particulate matter (PM) concentration have been observed, having a major influence of the operator's behavior. The best case scenario with the retrofit systems resulted in a significant efficiency increase and as well a reduction of CO, VOCs, and PM.
