I don't know how many of you have actually measured your fireboxes to compare to other stoves or to the specs but I did for the first time last night and was a bit surprised to see that my Hearthstone Heritage which is spec'd out to be 2.3 cubic feet only measures 21" wide, 10" deep, and 12" tall to the center of the sloped roof. That gives me a whopping 1.5 CF of firebox volume. Only 65% of what Hearthstone says it should be. What brought this up for me was when Todd measured his new Keystone at somewhere around 1.4CF with a half rack of MGD easily slipped into it. I thought to myself that I couldn't get much more in mine so I checked. Perhaps the tiny woodstocks aren't so tiny after all. Perhaps the mainstream brands have been using some trickery to make their stoves appear larger.
