I have a question that I would like advice on. I have just removed a lovely enamel oil burner from one of my rooms and replaced it with a wood burner. I have another two oil burners I need to replace, however before I do so, can I convert these oil burners to wood burners? Its seems such a waste and they are lovely items but hugely costly to run (and messy). I know I'll need to change the flue size, but I'm not sure if the actual burner itself can be converted. Could anyone advise please?
