Bis wann dürfen Kaminöfen betrieben werden?

The first Federal Immission Protection Regulation (1st BImSchV) deals with provisions for the use of small and medium-sized furnaces in the private, domestic area and in small commercial companies. The said combustion plants also include stoves, tiled stoves, stoves and ovens.

The requirements for the co-and fine dust values ​​of the systems have been increased and the approved limits are gradually reduced. For many owners of stoves, this raises the question of how long they may still operate their heating stove and which retrofits are needed if necessary.

First Federal Immission Protection Regulation (1st BImSchV)

In 2010, the 1st BImSchV was revised to respond to the increase in pollutant emissions in private households and to effect emission reduction. The focus of the regulation is small firing systems for solid fuels, pollutant limits and approved fuels. For example, new fireplaces have to comply with the following limit values ​​since January 2015:

  • Carbon monoxide: 1.25 grams / cubic meter exhaust
  • Fine dust: 0.04 grams / cubic meter exhaust gas
  • Efficiency: 73%

Which limit values ​​apply to old stoves?

However, from the regulation on small and medium-sized combustion plants, old stoves are affected. The limit values ​​are a bit higher here and the requirements thus slightly lower than new chimneys. Specifically, a stove that has been put into operation before 22.03.2010 must comply with the following limit values:

  • Carbon monoxide: 4 grams / cubic meter exhaust
  • Fine dust: 0.15 grams / cubic meter exhaust

How can compliance with the limits can be detected?

Compliance with the values ​​must be detectable. For this reason, it is important to ensure that the compliance with the required emission limits from the manufacturer are already considered when buying a firing plant. For older chimneys or loss of the certificate, a single measurement can be carried out by a chimney sweep alternatively.

When are the emission limit values?

How long an old heater may now be operated before requiring retrofitting or decommissioning depends on the age of the device. § 26 The BIMSCHV sets the following regulations in this regard:

  • Commissioning before 31.12.1974: The new limits apply to 31.12.2014
  • Commissioning from 01.01.1975: The new limits apply to 31.12.2017
  • Commissioning from 01.01.1985: The new limits apply to 31.12.2020
  • Commissioning between 01.01.1995 and 21.03.2010: The new limits apply to 31.12.2024

For heating systems which are put into operation from the 22.03.2010, the already mentioned, stricter limits apply. If the age of the system can not be determined, the 31.12.2014 already applies as the deadline for compliance with emission limits.

What happens if the limit values ​​do not comply?

If the stove does not hold the specified emission limit values, he must be taken out of service for the deadline. Alternatives are usually expensive, for example, the chimney can be retrofitted with a fine dust filter. Passive fine dust filters also offer a way to continue to use the fireplace, but must be respected here to the regular change of filter cassettes. According to corresponding retrofits, the fireplace must be removed again by the chimney sweep. Consumers who disregard the regulations of the Regulation can be imposed on fines of up to 50,000 euros.

Conclusion

The innovations of the first Federal Immission Protection Regulation raises the question, especially for owners of older stoves, how long they may still be operated. The respective key date depends on the age of the heater. Until this date, the stove must comply either by retrofitting the specified emission limit values ​​or be taken out of service. If you buy a stove after 2010, compliance with the limit values ​​should be accompanied by the manufacturer.
