Overview
- Active enforcement since January 2025 means stoves lacking required documentation can be officially shut down and owners referred to authorities.
- Appliances installed from 1995 to 2010 needed proof by December 31, 2024, units approved after March 21, 2010 already meet current standards, and many pre-1995 devices are either past deadlines or classed as historic.
- Owners can verify compliance via the HKI database or manufacturer certificates, or through a measurement by the chimney sweep, after which operation can resume if the unit meets limits.
- If limits are missed, options include retrofitting particle filters—roughly €600 for ceramic with maintenance needs or about €3,000 for electrostatic—or replacing the unit, with state subsidies reported up to about 70% in some cases.
- Exceptions apply for certain installations, including pre-1950 historic stoves, sole heating sources, hand-built storage stoves, and open fireplaces under limited use; fines for unlawful operation can reach up to €50,000.
