ditchrider said:I also love watching the flame patterns one my stove. The Earth Stove I had used to just smolder and creosote the chimney when I shut the air down to get a longer burn. I can see in the Hearthstone how effective the air manifolds are. As startup with the air supply wide open, they just shoot flame all over the place, reburning the wood gases. I read other reviews of Woodstock stoves and folks have split opinions about the maintenance of the catalytic converter. Personally, I wasn't excited about that feature. But honestly, I have no firsthand experience with it. But to me, if you get a cleaner burn with the cat stoves but throw away or dispose of through a recycling center, it's a moot point environmentally speaking. Again, just my opinion. Other people reviewing the Hearthstone stoves seemed more pleased not having to deal with it and they also appreciated the fire viewing with the Hearthstones if they were pleased with the stove. I found mixed reviews about most any brand of stove and believe there are a lot of mechanical issues with the draft patterns of different homes that need to be considered when deciding if a stove works well or not.
The cleaner burn isn't the main benefit of a cat stove. All EPA stoves are pretty close in terms of emissions. Longer burns are more of a direct result of a cat stove. My catalytic Encore burns longer and at a higher temp than the Heritage does. The Fireview gets longer burns than the Encore and the Heritage.
There is an additional maintenance cost using a catalytic stove and an additional lever for controls to engage the cat. For some, it is not worth it, but others like the system and the benefits of longer burn times.
