great post! lets see how YUKON furnaces interact with this via CRAPPIEKEITH.
Keith can answer also, but I'd like to weigh in, as an owner of a yukon. I will try to be non-biased, but I do this knowing that like a lot of us on here, I want to defend the decisions I have made for a furnace.
First of all, I like the energy king (ek), it has a window (or so they say, I still haven't see the window model in pics, except the one photoshopped with a fire in the widow
photoshoped pic ) on the front door, I wish my Yukon had a window. I also like the way they create the secondary burn better than the yukon (I'm not sure why I like it better, not a scientific reason, maybe because it is more like all of those wood stoves with secondary burn tubes. But I'm guessing that the secondary burn tubes on the ek will need to be replaced about every 7 years or so, the warranty is for 6 years, do the math). If my yukon had a front window, then I'd say that I had the perfect furnace.
That said, the yukon is a tank, lots of steal, and built to last 30 years or longer (that is the warranty). I heated a 4800 sq ft house to 74 degrees (who said they wanted some numbers?), on 4 to 5 cords of not well seasoned wood (mostly elm, some hedge when it got really cold). I got burn times of 8 hours (by the end of the season, took me all season to learn how to do that), but it sits in an uninsulated garage (I bought drywall and insulation this week, any volunteers?), so I lost a lot of heat to heating the garage.
The yukon has a great design, and (I can't find the figures on either web sight, so this is opinion) more surface area, and better design on the secondary heat exchanger.
.06 draft (ek) would burn through more wood then .03 (yukon), just by the amount of air you are allowing through the furnace and up the chimney.
However, If I were yukon, I would be figuring out how to qualify for the tax credit, if all it takes is changing the secondary burn path and a window in the front door, then I would make those changes.
So if I were buying today, I would go with the yukon for the warranty (30 years vs 6), but I would have a hard time passing on the 1500 tax credit this year. If the warranties were both 30 years, I'd buy the ek for the window, I'd like to see my secondary burn.
