Hello, this is my first post...so here it goes.I have a Harman Accentra, and an Enviro Empress, the other day I tried these pellets, and they are dark and are not premium pellets, but they put out a lot of heat, and the Harman is a bottom-fed appliance, so it the semi-hard ash was pushed right out the way.The reason why I am bringing this up, is because I have seen an intrest in these here, and also, on the bag it states these pellets work best on bottom-fed stoves...Thanks
