KIUAS projects

Sauna stoves have the highest emissions out of all fireplaces. Approximately half of Finland’s fine particle emissions originate from wood burning in households, and sauna stoves account for a significant share of these emissions. The KIUAS projects aims to reduce the emissions from wood-burning sauna stoves.

The KIUAS project (2017−2019) measured the emissions of the most common wood-burning sauna stoves. The project developed a measuring concept that can be used to measure and compare the emissions of sauna stoves in real-world conditions. At the same time, residents were provided with information on how to use the sauna while keeping the emissions as low as possible, thereby improving the air quality in their own residential area.

The KIUAS2 project (2019−2023) continues the work started on sauna stoves, focusing on stove development. In addition, the criteria for the voluntary environmental label proposed in the KIUAS project will be assessed and, if necessary, further developed for possible introduction.

The parties to the research project are: the University of Eastern Finland, Harvia Finland Oy, Narvi Oy, Teuvan Keitintehdas Oy, Misa Oy, Muko Oy, Premec Oy, IKI-Kiuas Oy, Metallitekniikka Hannu Laaja, Ministry of Social Affairs and Health, Ministry of the Environment, Helsinki Region Environmental Services Authority HSY, City of Helsinki, City of Kuopio, City of Turku, City of Tampere, City of Lahti, City of Vantaa, City of Espoo, and the Finnish Home Owners’ Association.
