Dust Collector FAQs: Does the type of chimney matter when installing an electrostatic dust collector?

In principle, any type of chimney suitable for a wood-burning stove can be fitted with a dust collector, whether it is made of metal, concrete or brick. It is important that the chimney is in good condition and structurally suitable for the installation or construction of a dust collector. In some cases, a chimney renovation […]

Dust Collector FAQs: How much does an electrostatic precipitator cost?

It is difficult to give a general answer as the installation of the collector is very individual. For example, the total cost depends on where the collector is installed, how accessible the installation site is, and whether other work is required, such as a chimney renovation (which is usually overdue anyway) or the installation of […]

Dust Collector FAQs: How does an electrostatic filter work?

The principle is similar to rubbing a balloon against your sweater. This creates an electric field that can make your hair stand on end. The electrostatic filter also creates a magnetic field with voltage, which it uses to charge the dust particles. The charged particles then stick to the wall of the chimney and clump […]

Frequently Asked Questions: Where can I buy an electrostatic filter?

You can buy an electrostatic filter from a stove builder, stove dealer or specialist dealer. The addresses of stove builders can be found on the Gesamtverband Ofenbau e.V. GVOB website at https://www.kachelofenwelt.de/service/kachelofenbauer-adressen/. It is important that the dealer also offers advice or carries out the installation. The more specialised a dealer is in fireplaces and […]

Dust Collector FAQs: What are the legal benefits of installing an electrostatic precipitator?

The Federal Immission Control Act and the 1st BImSchV Ordinance for stoves and tiled stoves stipulate that appliances tested between 1 January 1995 and 21 March 2010 must emit a maximum of 4 grams of carbon monoxide per cubic metre of flue gas and a maximum of 0.15 grams of particulate matter per cubic metre […]

Dust extractor FAQs: Does the dust extractor need to be inspected by a chimney sweep?

Yes, because it is a modification to the flue system. The chimney sweep will take into account whether the chimney cross-section is changed, the distance to combustible materials and whether other building regulations are complied with. It is advisable to consult the chimney sweep before installation.

Dust Collector FAQs: What approvals should a dust collector have?

The German Institute for Building Technology (DIBt) issues building approval on the basis of test reports from independent testing institutes. The approval or test specifications include technical details such as the degree of separation (efficiency), the area of application (e.g. pellets and/or logs) for the separator and the corresponding accessories. The electronic control unit must […]

Dust Collector FAQs: Is the electrostatic precipitator mandatory in Germany?

No, neither electrostatic precipitators nor catalytic converters or passive filters are mandatory in Germany. However, it is conceivable that future legislation will set lower limits for wood-burning stoves and fireplaces. A particulate filter would then be the most efficient way to effectively reduce particulate matter (from 2024).
