I think I saw a couple of Oakwood owners over on gardenweb.com in the home forums fireplaces section. You might want to enquire there if no response here. It looks like a nice stove and Harman has a good reputation.
i have a harman tl 200 wood stove, what a great unit!! after 3 years it still goes strong, lots of heat great burn time and a good looker with the gold options, the best part is the top loading, no bending down stuffing it full at night!! and yes u can stack it right to the top!
from what i hear the oakwood is a cast iron brother of the tl 200, i think its a top load and also a good looker!
Harman is a great unit, ash door on bottom blower kit, and cooking grates if u wish (great when power goes out)
i would recomend it but most inportant is the top load!
