What to look for if I go to check out? Supposed to be lightly used at lake home. Whats the stove worth? when did Harman make the Accentra 12volt backup or am I just getting a 12 volt exaust fan? We really like the small fire that its capable of for the cool spot in the kitchen dining area that the main Harman is close to making comfortable but is just short of with winter in its full wrath and use in shouldering.
