Protect your family from the silent killer. Learn how to safely operate your wood burner and prevent carbon monoxide poisoning.
The invisible threat that claims lives every year
Carbon monoxide (CO) is a colourless, odourless, and tasteless gas produced when fuels like wood, gas, oil, or coal don't burn completely. It's often called the "silent killer" because you can't see, smell, or taste it.
Wood burners produce CO if there's insufficient oxygen for complete combustion, or if the chimney is blocked or leaking. Improperly installed or maintained stoves significantly increase the risk.
UK deaths annually from accidental CO poisoning
NHS hospital admissions yearly
Incidents linked to solid fuel appliances
Know the warning signs and act fast
Important: Symptoms often improve when leaving the property and return upon returning - this is a key indicator of CO poisoning.
Essential safety measures for every wood burner owner
Fit an audible CO alarm in every room with a fuel-burning appliance. Test monthly and replace batteries yearly.
Have your chimney swept at least once a year by a HETAS certified professional to prevent blockages.
Burn only dry, seasoned hardwood with moisture content below 20%. Wet wood produces more CO.
Never block air vents or airbricks. Proper airflow is essential for complete combustion.
Check flues, pipes, and seals regularly for damage, cracks, or disconnections.
Always use a registered engineer for installation. Register your appliance with HETAS.
Always choose a CO alarm that meets British Standards BS EN 50291-1 and carries the British Kitemark.
