I'm trying a few bags of Somersets and have noticed that they seem to be burning at a faster rate than I remember. I've got the feed rate on 3, low burn on 4, main controls on 1 (heat) and 3 (blower). Hasn't been too cold until last night which allowed for an informal test of two bags. Happy with the heat output which is great and ash seems reasonably low. Anyone notice the same thing?
