The Best Fuels to Burn in a Chimenea

Ash
Beech
Birch
Avoid burning freshly cut or wet wood as it produces excessive smoke.
Charcoal
Charcoal is another popular option when deciding what to burn in a chimenea.
Advantages include:

Produces less smoke
Ideal for cooking in chimeneas with grills
Charcoal is commonly used when the chimenea is being used as a garden cooker or BBQ.
Smokeless Fuels
Some chimeneas, particularly cast iron or steel models, can burn smokeless fuels such as:
Manufactured smokeless coal
Briquettes
These fuels can burn for longer periods and provide consistent heat.
Fuels You Should Not Burn in a Chimenea
Although chimeneas can burn different materials, some fuels should never be used.
Avoid burning:
Treated or painted wood
Construction timber
Plastic or rubbish
Coal in clay chimeneas (too hot)
These materials can release harmful fumes and may damage your chimenea.

Firewood
Kindling
They should avoid extremely high-temperature fuels like coal.
Cast Iron or Steel Chimeneas
Metal chimeneas are more durable and can burn:

Charcoal
Some smokeless fuels
These chimeneas are often better suited for cooking and long burns.
