It’s really a multifuel burner (an Aarrow Becton 7). We ran it on smokeless fuel last winter.We were thinking of replacing it with a gas fire last winter but we decided to keep it for another year and run it on logs.
Smokeless fuel is usually dearer than logs per Kg but has a higher heat output. But it takes quite a time for the burner to start giving out heat after lighting and quite a time for it to die down. And it leaves the ashpan full which has to be emptied every day.
Logs start burning hard within minutes, and at the end of the night the fire goes out quickly, and there is very little ash. The ashpan only needs emptying once a week.
