They are quite different. They 1800 and 2000 model seem to be well received without a lot of problems. They are more picky about the draft and dry wood then the NC-30 put perform well otherwise. The 2400 is in a category by itself . While a great looking ,clean burning large stove with a huge viewing glass it has door issues. If choosing this stove, ck it carefully for door and stove body warpage before you buy. Has a tendency to leak air around the door if you get a bad one.Those of you who have a Summer's Heat by England's Wood Stove: Do you like it? How would it be different from the other Englander models?
