I came across that a while back, I really like it. As someone said, I might be 'choking' my flame covering it with wood. I'll try to be more deliberate getting it lit quickly to generate heat and no smoke initially.Well talk about teaching old dogs new tricks,. I've been lighting fires of one sort or another for 70 years and heared about this method which I didn't really believe.
Just a big leaky Victorian house But is the idea I want to 'seal' the room temporarily to stop the air circulation down the flue? I could try to shut the door and put a draught excluder across it to see if it helps.It could be a bathroom or kitchen fan causing it. Try a candle in there to warm it up...
A candle or something is interesting to test as well. Thanks.
