Update to prior post. Moved the gasification boiler to my new shop, 1500 sq ft, 14 ft sidewalls, in-floor radiant, and 1000 gallons pressurized storage. After 3 heating seasons in the new shop, I still say that I could not be more satisfied. Burn at most once every other day during the coldest winter (-30F range), 4-6 hour burn time; burn less frequently during mild periods. Aspen and pine are primary fuels. About as effortless as a wood-fired, efficient, nearly smoke-free boiler could be. Now after 6 heating seasons, no repairs, no breakdowns, no replacement parts, just normal cleaning maintenance.
Hard to say that there are any cons when a person understands how the Tarm operates. Need dry stove wood (20% moisture content), relatively small spits (up to about 6"), and I dry the wood in outdoor stacks two full summer seasons. I have about 8-10 cords on hand at the start of each heating season, and burn 4-5 cords each season. I suppose a "con" might be that I brush the firetubes and remove excess ash about 1-2 times/month. This takes about 20 minutes each time. Other "cons" may be that there is a learning curve to achieve near effortless operation, and that storage is essential to realize the full potential and ease of operation this boiler offers.
I had an outdoor wood boiler before (OWB) and burned 2-3 times the wood, generated lots of smoke and lots of ash. This Tarm is so much more efficient and about as easy to operate as the OWB. I have the Tarm and storage installed in my shop, so any heat thrown off by the boiler and stack, plus from the well-insulated storage tank, also heat the shop. Through careful temperature data logging, wood weighing, and calculations, I have determined that efficiency in converting wood btu's into heat is in the mid-80% range, which I regard as excellent.
