Just started researching here and though I would try and get some info from you here. I was ready to pull the trigger on a Heatilator eco insert $1200, then I found a used Lopi at a fireplace store for $950 he says it works great has blower 1998-2000 model, the fire box is around 1.8'. My house is about 1100sf on the main level which is what I'm trying to heat with this unit alone, will this get the job done? 50,000-60,000 BTU?
