Look at what the low heat BTU rating is. A unit which is too big may only be able to scale down to 12,000 or so. 8000 btu will heat the apartment very nice once the area is up to temp. I carry The Regency Greenfire, which is theexact same stove as the Enviro Meridian and the Vista Flame VS100. Any of these three is great, you may also want to check out The quadra-fire Sante Fe, Enviro MINI and Empress, The Harman XXV, the Hudson River Saratoga, BOSCA Spirit (nice ;-) )...if you need more choices you'll never decide on anything.
Some here on the forum may know how I feel about dealer service....I wouldn't rely on it as a total deciding factor, there are there are other options out there,
...besides, you have us here in the forum.
