Hoping this thread helps some folks. I upgraded from a modified (not by me) old Earth Stove to the Liberty. Backstory: I bought the Earth Stove used almost 20 years ago, with 6' of Metal-Fab double pipe for $150. I bought all the other pieces (more pipe, cap, flashing, ceiling box etc) directly from Metal-Fab. It has served us VERY WELL...Earth Stoves are beasts (2500 feet of sprawling ranch-style house). But it was time to upgrade due to inefficiency and physical failure of the stove (air control no longer working). I was looking at the Liberty and the Green Mountain 80, I went for the Liberty. It was installed today, and I had the pleasure of doing the paint cure burn (it was 75 here, so all windows and doors were open). I spent the day playing with the bypass, the air flow, and loading different size splits in different orientations...I'm so giddy. I'm looking forward to the increased efficiency and ease of a modern stove. Big cold front coming this weekend, I think the electric furnace will be getting a break.
