Our usual coal merchant stopped selling the one we usually got (Ovoids - smokeless) and this year we got 3 sacks of something called Newburn and it's absolutely crap. Usually with Ovoids the stove can make most of the house warm but this Newburn stuff was a massive waste of £90, unless you stand directly in front of the stove there is just no heat in it whatsoever, even with two fans on top. DH has asked me to find a better one but I don't know where to even ask or look!
