Grace period for old wood fires expires at the end of 2020

Fireplaces and tiled stoves increase the living comfort CO2-neutral in the cold season.Outside of your own four walls, however, the approximately eleven million plants in Germany ensure fine dust in the air.Since 2015, new single room fireplaces have had to meet stricter requirements.Now the transition period for before 1.January 1995 built fireplaces.The dust limit is now 0.15 grams per cubic meter exhaust gas, the carbon monoxide limit is four grams per cubic meter.The legal basis is the ordinance on small and medium -sized combustion plants, which 1.Federal Immission Protection Ordinance (1.BImSchV).For systems built before 1985, the deadline ended on 31.December 2017.

Particle filters do not help against carbon monoxide

"If the fireplace has excessive dust emissions, the installation of a particle filter can reduce the emissions under the demanded threshold," says Frank Hettler from the future old building.“If the emissions of carbon monoxide are too high, however, only a decommissioning of the old oven helps.“The invisible, toxic gas is not removed by any filter.Experts go from 200.000 to two million ovens with excessive emissions.

Whether an oven falls into the age group in question before 1995 can be determined on the basis of the type sign."If the date on the old signs can no longer be determined or the type sign is completely missing, a look at the manufacturer's certificate is also worthwhile, also mentioned test bench measuring certificate," says Jörg Knapp from the Sanitary Heating Climate Baden-Württemberg.If there are no documents for this either, homeowners on the Internet could look at the home, heating and kitchen technology on a database of the industrial association, so briefly.Here is also, but not for all stoves, the height of the emissions.If this does not help either, contact with a specialist in the stove and air heating farming is recommended.If the year of construction or emissions cannot be determined, the fireplace must be replaced.

With Ü25 ovens, an exchange is usually worthwhile

Experts recommend refraining from emission measurement and possible retrofitting in the plants over 25 years old.."In many cases, measurement and retrofitting are more expensive than a complete new oven," explains Knapp.Measurements cost 100 to 300 euros, particle filters for dust including installation up to 1.500 euro.For this amount, homeowners already receive a new device together with installation.

A complete exchange offers further advantages.New wood fires expose up to 85 percent fewer emissions than many old devices and need up to a third less fuel.Due to their higher efficiency, the new systems are more energy -saving.The investment therefore pays off."For this reason alone, the oven exchange should not be pushed onto the long bench," advises Frank Hettler from the future old building.Even with old plants that meet the requirements, homeowners should think about renewal.With them, an exchange will also lead to lower operating costs.

In addition: new stoves meet level two of the 1.BIMSCHV and due to their low -emission technology can also be operated with fine dust alarm on days.For house owners in fine dust -plagued cities like Stuttgart, this is an enormous advantage.

Which ovens fall under the regulation?

All walled fireplaces such as fireplace or tiled stoves with an industrial heating insert and an output of at least four kilowatts fall under the regulation.You must also be lockable with a door.Raumer heaters such as Sweden ovens that do not have a conversion must also be retrofitted.

The regulation does not apply to open fireplaces, craftsmanship and herds of cooking, as well as closed chimneys, which may also be operated in the open state.Historical stoves that have been shown to.January 1950 was also not under the regulation.However, if the owners have implemented the stove in the house or apartment in the course of the company, it is treated as a new system by the legislator.For him ends on 31.December 2020 the grace period.Source: Future old building / pgl
