Anthracite is a naturally occurring smokeless fuel. It is very shiny, hard and dense. It's extremely slow burning with a very high heat output.
Most quality anthracite is produced by Celtic Energy Ltd in South Wales, but there are also several private anthracite producers who supply fuel for the domestic market.
Various sizes of anthracite are available and the correct size should be selected for your appliance. A summary is provided below, but please check with your Approved Coal Merchant before ordering.
