NH already had banned the sale of new OWBs but they now are banning the sale and installation of used non EPA OWBs http://www.fosters.com/news/20170907/new-law-bans-older-uncertified-outdoor-wood-boilers.
There has been abuse of the prior state law which banned the sale of non certified new OWBs. Folks were buying effectively brand new OWBs usually from out of state being sold as "used" by various sellers. The buyer still has to meet some fairly restrictive rules to legally install them, but the state had elected not to prosecute buyers who may not have understood the rules.
I personally have had issues with a neighbor who installed a used OWB ignoring the rules in place for siting (a minimum of 200 feet from the nearest abutter with a stack discharge above the roof line of the nearest adjacent home within 300 feet). After several complaints to the town he improved the installation by installing a taller stack but it still was an issue. Heating oil was cheap the last couple of winters so he shifted away from using it during shoulder seasons which helped a lot. I expect his spouse and family probably appreciated it also as the low level acrid smoke is pretty unpleasant.
