I live in California and am looking at units like the Montecito Estate or NZ6000 as I would like a fireplace capable of heating but my wife would like one that can be more like a traditional fireplace (at times) by operating with the doors open. Also weather is mild compared to Canada. Any recommendations on a unit that will fit both our needs. One dealer told me the high efficient units as I mentioned above really emit a lot of smoke with open door wood burning. Thanks
