Found out about Eshland back in the early 80's with a ES 250 Gassification boiler in a mountaintop location in NH. The beast heated 7000sq ft easily and NO creosote. I knew nothing of gassification at that time, but later saw an ES 180 gasification boiler in the 10,000 sq ft Nichols Hardware Bldg in Lyme, NH. It is still there, hooked up, used when needed.
By the way, Nichol's is Tarm USA and one of the oldest wood, coal, gas stove and boiler distributors in the East. They now have a Tarm Pellet boiler heating the building, not because anything is wrong with the 180, just a new demo product.
Anyway, from there I looked over the multifuel AHS boiler and was favorably impressed again. Then I looked at an AHS 130 and a 260 and liked what I saw. I called AHS directly just to ask a few questions and was greeted by the President of the company who was extremely helpful and invited me to visit when in the area. Can you teach an 'old dawg' new tricks? Yup.
I think AHS could use the motto: "Change occurs when someone sees the next step." They saw it, did something about it and run their business 'straight up'. What you see is what you get, no BS, no hog-tails, no phony delivery dates and they update their products without notice, not to make it cheaper, but to make it better. Would I buy one? I just did two weeks ago.
