EPA cert stove will also radiate more heat per cord, than non-EPA...
Which translates to less work/cost for heating.
What would really be helpful is:
~pictures of home,
~layout and dimensions of home,
~insulation specs of said home,
~budget,
~time available to project,
~construction related experience,
~Lifestyle, are you home all day/evening in winter or do you leave for hours on end,
~primary heat source/secondary,
~What is your current heat source (it's rating, typical fuel usage in a season/year)
~Where in your home do you want to place it
~Who will be operating it (children, disabled, ect..) Some stoves are easier on the user than others.
~Can you wake up too a cool house, or do you need a long burn time for sleeping in/going out?...
Basically tell us a little more about you and your situation.
Like buying a car, you're not not just buying it based on MPG, MSRP, HP or any other stat. You want it to fit with your lifestyle. So we'd need to know a little about your lifestyle.
Biggest question: Do you have a maul/axe, chainsaw or woodpile CSS (cut split and stacked) already? I learned the hard way that is the first purchase a wood heater should make.
