What is the longest non-cat burning stove on the market today that you can buy?? I currently own a Wonderwood circulator wood stove which does not do bad, but I am only getting around 4-5 hours of burn time. I would like to find a wood stove that can get somewhere around 7-8 hours at least so I don't have to get up every morning around 2-3AM to put more wood on the fire to keep it going. I know the cat stoves will burn much longer, but I don't want to worry about the maintenance and I have heard the cat stoves can have issues with creosote building up. Any input is much appreciated!
