Multifuel stoves have a riddling grate on the base that has air gaps that can be shut off or opened, the ash falls to an ash pan below that can be removed to empty.   Logs should be burnt on a bed of ash; this will help them burn efficiently. Smokeless fuel can be purchased from most garages / garden centres.   Smokeless fuel burns slower and hotter.

Log burner – logs burn better from the top so the base of the log burner is normally flat with no holes. You’ll need to use a shovel and brush to clear out the base.
