Fortunately, with the right measures – a Spark arrester, regularly chimney sweeping and correct heating behavior – enjoy your wood stove safely and be well insured.

  • 👷 Approved company: ASPB member or certified chimney sweep

The fire brigade recommends this method for cleaner combustion with less smoke and creosote:

1
Air supply Open

Open the air valve fully for good oxygen

2
Thick Blocks Below

Place large logs parallel on the bottom

3
Cross Stacking

Place smaller blocks crosswise on top

4
Light From Above

Light on top with a fire starter

✓ White/transparent smoke = clean combustion | ✗ Black/gray smoke = incomplete combustion

🪵 Storing Tips for Safe Use

  • Dry wood: Dried for at least 2-3 years, less than 20% moisture (measure with moisture meter)
  • Unprocessed wood: No painted, varnished or impregnated wood
  • Zero waste: Never burn paper, cardboard or household waste
  • Do not smother: Do not pinch off the air for slow burning
  • Allow to burn out: Do not smolder, close air supply
  • Cleaning up ash: Carefully in a metal container, never in a plastic bag
  • Dry periods: DO NOT heat during prolonged drought
