just saw the e-classic yesterday at a power show. this is the cb gasification outside boiler. downdraft gasification don't know about heat exchangers inside for outside use like the owb looks big holds like 400gal water can be duel fuel if needed all other features same as there owb. price 8500 for wood only, 8900 duel fuel this boiler has the only epa orange tag on the market so far. this is for owb emissions and this is only because they must have beat other owb manf. to it. the salespeople of course didn't know anything about it and i knew more about gasifiers than them which isn't hard. they just kept saying this is knew technology and i kept telling them no its not. i wanted to tear into it and trust me i tried but they kept saying we cant take all the panels off since they are still factory screwed together from shipping. i wanted to see the heat exchange area and ash pan area but no luck. all in all it looked like a solid boiler and a lower price than i thought it would be for a 500 btu rating which is way to big for my needs or a small towns needs. i asked about the smaller boiler that is suppose to come out but he said they prob wont make that one for some reason. dont think this is on my list since so new and cb dont know gasifiers that well yet.
