I"m in Iowa, I've just been tossing the idea around somewhat, but I'm not spending anything like the 41k, let alone the 71k, most of those boilers are over a million or two btu's and far larger than my needs, was just wondering if the concept worked and how efficient they are. I've talked to several salesmen and they claim production for that 500,000-800-000 btu units production can't meet demand and customers wanting them can't get those units, one claimed he had over a 40 people on a waiting list for top loaders right now and is getting one or two more each week. Not sure if its sales hype or not, but I've talked to a couple people in my area who are wondering the same thing I am, do they work, how efficient are they and what's the long term durability of them.
I could save having to split 90 percent of what I currently split, and save a lot of chainsaw work just to fit the stuff in managable size to hand feed a boiler, the outcome would be the same, heating builidings, but the labor savings would amount to a lot over a decade or more, not yet sure if its worth the cost, but asking many questions.
The models and makes woodbutcher posted I can't find any information on anywhere, have seen several other makers units in video's or on their websites, but none in person.
