I wonder if anyone has any ideas about this. Our wood burner is a mufti fuel and in the winter we keep it going overnight and thro most of the next day with a load of coal, the wee eggs type. This year a new coal supplier has persuaded us to take anthracite
its disastrous!doesnt stay in, turns to clinker and goes out if we put more on top.
what in earth do we do, we have 10 bags of the stricken stuff lying in top of last years which was ok!!
