I just purchased a Hearthstone Heritage 8024 to replace a Waterford Trinity that heated my house well for many years. The Heritage claims up to 60,000 BTU vs. Trinitys 55,000, so I thought I was all set. Only later did I note in the owner manual (but not in any sales material!) that the EPA listed max BTUs for Heritage are less than the Trinity, 35,845 vs 43,800. Anyone with any experience think I may have a problem? Shouldn't Hearthstone put these EPA numbers in their sales material?
