I'll be relocating to Wisconsin in a couple of years and will need to set up a new gasification system. I'm currently running an EKO 60 and think it's a fine boiler, but it looks to be discontinued in this country. I'd think about getting a Biomass, but figure maybe it pays to go top shelf with a lambda system. (Not interested in a Garn, as good as they are, so don't bother trying to convince me to buy one). I haven't really done much research but I see that AHONA sells the Vigas 60 with lambda control, and Tarm sells the lambda Froeling, but only a 20-30 kw model, according to the website. Neither offers prices, so I'm curious about that as well. Also curious about the advantages of the lambda sensor vs no lambda. Any other rigs I should be looking at? I'll be burning very dry oak and locust with 1,500 gallons of pressurized storage. Any and all thoughts and other suggestions are welcome.
