Frequently asked questions about fireplace cassettes

The most important questions about fireplaces and heating at a glance.

Sorry, no matching search results were found.

A fireplace cassette is a closed insert that is installed in an open fireplace. It works like a modern fireplace insert: the fire burns behind a glass pane in a closed combustion chamber, which makes combustion more efficient, safer and cleaner. The heat is released into the room in a more targeted manner.

Yes, definitely. A fireplace cassette has several advantages:

  • Less heat loss → more efficiency
  • Fewer emissions → better for the environment and health
  • More safety → no flying sparks, no open flames
  • Legal compliance → meets current requirements (BImSchV & EU Ecodesign Directive)

What's more, you don't have to demolish the old fireplace - the cassette is installed to fit perfectly.

And best of all, the conversion is more sustainable and generally more cost-effective than building a new closed fireplace.

As a rule, you do not need planning permission. However, the installation must be carried out by a specialist company and approved by an authorized chimney sweep. Among other things, the chimney sweep checks the suitability of the chimney and compliance with legal regulations.

The basic requirement is a stable, open fireplace with a functioning flue (chimney). The dimensions also play a role - but even for unusual dimensions, we at Spartherm offer custom-made solutions. Your specialist dealer will advise you individually.

Our fireplace cassettes are designed for logs. The fire experience with wood is authentic, sustainable and CO₂-neutral - provided you use dry, untreated firewood.

 

What you should bear in mind when burning wood

Installation is carried out by experienced specialist dealers. In most cases, the conversion takes less than a day - provided your open fireplace is in good structural condition. It may take a little longer for individual requirements or special dimensions.

Thanks to the closed design, your living room remains soot-free. The pane can be cleaned with a special fireplace glass cleaner. Regular maintenance (at least once a year) by a specialist company ensures long-term operational safety.
