Given the changes this country has endured in the past 10 years, I would not trust that things could not get ugly quickly, as far as regs are concerned. I love Kentucky, and I have said what u say for years. People down there will not stand for meddling in their business. My entended family is from arkansas. They don't care much for regs either. My observations were based on the uproar in the NE states and proposed legislation that would require replacement in a particular timeframe. Heck, they are trying to regulate dust in Iowa. Lots of things have changed here very quickly. For the record, I have a downdraft unit and do not find it to be complicated at all. Maybe some are, with lots of electronics and such. I find that I am intrigued by my unit and monitor and log the temps, wood used, cleanouts, etc. more than is required. I fill/check it twice a day. Seems to give the best burn. Been laid up the last week , so son has been stuffing full, and getting a much longer burn, but sometimes more smoke on start. So it all boils down to proper use. Anybody who opts for an OWB has got to commit to its proper operation or we all may pay in the long run. My decision was made by the tax incentive. Unit was same price as regular unit, but is phase 2 cert.
