Insurance wont allow a free standing stove. I would like to install a zero clearance wood insert but can not find anything that comes close to blaze king Princess insert. Blaze King currently has no zero clearance models. Installing masonry would cost close to 10k so out of budget. So with my research I found two models with up to 12 hour burn time, the Fireplace Extraordinaire Apex 42 and Lopi Hybrid Fyre large flush wood model. Can these actually get 12 hours out of them? any first hand experience? any other model out there to consider?
