Here is a shot of my new 2005 Harman XXV. You may notice I am a real firebug, having a pellet stove right by my 1987 BIS (Built In Stove) made by Security Chimneys. Last Year I burned a Harman Accentra and have now traded for the XXV. Last year we heated the whole house with pellets, never turning the LP furnace on one time! I didn't keep good track of how many pellets I burned last year but will have an accurate count by end of the season. We switched to pellet last year because my wife went to work full time and it was not convenient to keep the BIS going. How would I compare the XXV to the Accentra? Wow, they are both great. I think the Accentra was a little quieter than XXV by a little bit. I like the bigger glass of the XXV and the one way glass. You can not see into the stove when its not on, thereby not seeing the dirty burn pot. The Accentra glass seemed to stay a little cleaner but being some smaller may be why. I have fallen in love with the new XXV's styling. That's the real reason why we changed. All in all, I think they are both equal in quality and both do what they say what they will do. The XXV is a real heater!
