Purchased a gasser this spring. Upon arrival inspection it became apparent it was crude (real crude), very poor welding and just crappy workmanship. Talked to dealer, he agreed to take back, and he asked if I would consider Vigas. He had never sold one, just starting in them but thought the workmanship was pretty good. Long story short I talked to Mark at AHONA, read everything I could, called him again etc. Bought a Vigas 60 with Lambda, draft inducer and chimney temp probe. Been in operation now for 3 weeks. (once every day or two to heat 1200 gal. storage). Took a few days to understand the computer controls and what they were doing, but after that just light wait 15 min. load up with amount of wood needed and leave. I have burnt Pine splits 24" long and 8%, cut up pallets, some Cottonwood, Aspen (dry) then some Poplar and Aspen a bit wetter (around 20% or a bit more) a whole bunch of dimension lumber and some old logs laying in the grass. Burned the whole works clean. Rarely do I buy anything and have it perform above expectations or as advertised. As you may guess I am happy. Anything at all to complain about, well maybe. The manual is so - so. Translated and not quite enough info. The inducer fan works great for lighting fire and helps smoke control, but it does smoke if door opened wide. I can see a hood in my future. Thats my two bits worth.
