The EPA was the driving force behind the changeover. In 1989 wood stoves that did not meet EPA standards could not be sold in the USA.
It is also illegal to sell a used non EPA wood stove.
Is it illegal to sell a non epa stove used?
One other thing ppl forget with OWBs is they are doing the entire heating structure,and hot water in most cases,where wood stoves inside are usually supplimental heat,heating 60-90% of the houses space,and do not do the domestic hot water .OWBs are also heating the outside air a little bit as well.I know there are gains ot be had in OWB efficiency,but they will never burn as little wood as an indoor unit.
