Reduce smoke from your domestic fire through these energy-efficient practices. Aim to produce little or no smoke from your chimney.

What you can burn

• Burn dry, well-seasoned wood that has been split properly. Dry wood has large cracks at the end of the log.
• Burn low-sulphur coal (0.5 per cent or less by weight). High-sulphur coal produces more smoke, odour and harmful emissions.

• Do not use wet wood.
• Never use green wood.
• Never use treated timber. These generate toxic substances.
• Do not burn rubbish, glossy paper and wrappers. These produce chemicals and odorous smoke.

• Stack wood loosely in the firebox so air can circulate.
• Use enough kindling.
• Start the fire with paper, dry kindling or an approved commercially available fire lighter. Never use accelerants such as petrol.
• Do not put too much firewood in at first.

• Keep the fire burning brightly. The brighter the fire, the less smoke it produces.
• Burn smaller logs rather than trying to burn a single, large log.
• Keep the air control open for at least 30 minutes.
• When you add logs, open up the air control to high for at least 20 to 30 minutes before turning it down.
• Do not keep the fire burning overnight.
• Do not add a full load of wood when there are only a few glowing embers. This causes excessive smoke for long periods.

• Regularly remove ashes from the burner or fireplace.
• Have your woodburner checked if it is smoking excessively.
• Have a professional clean your chimney or flue every year.
• Do not repair your woodburner as this is unsafe.
• If your burner is more than 10 years old, upgrade to an authorised woodburner, heat pump, flued gas or pellet fire.

• Split your logs. Logs dry faster when split, so split wood into pieces about 10cm thick before storing.
• Stack wood loosely off the ground in a criss-cross pattern to let dry air circulate around it.
• Get your wood supply in the summer. Freshly cut wood must be stored for 8-12 months to allow it to dry properly for good burning.
