I work at a dealer in nova scotia where we sell ja roby products including the ultimate, the mystere and that monstrosity of a stove/furnace, the atf 727, and there have been a few issues, if you look inside the ultimate you will notice a steel structure that would resemble a log holder of sorts, this structure draws a tremendous amount of air through, resulting in two instances of this structure completely melting!! this large plume of secondary air has also caused the tubes responsible for the reburn element of the stove to warp and fall into the firebox. JA is excellent in resolving customer issues, but until this issue is resolved id be cautious in purchasing this stove

Thanks for the update robar. Good to know. What are some of the most popular brands that you sell?
 
My firebox is larger than that at about 5 feet cubed. It has a factory 6" flue and performs fine and has for over 30 years. In fact, this stove model is so popular on Cape Cod that multiple shops build them, to this day.

Those currently being built are virtualy identical to the origninal tempwoods, with the exception of a tiny baffle just before the flue outlet.
 
What makes it the "Ultimate"? Anything other than size. I guess they had to come up with a name.
 
There are two versions of the Roby wood furnaces, link below. I have spoken to these people and i am not certain about their intentions, nice furnaces and all but they lack certain information like wood consumption even at the most basic levels. The same can be said for PSG and Drolet all they seem to do is quote the spec sheet and that isn't all the useful and not many people comment on how much wood they use with those furnaces which really isn't all that hard to figure out. Looks like Airstove odf 1500 or 2000 or yukon-eagle superjack are the only real contenders that not only match epa requirements but have controls that limit the burning of the wood so it's not wasted as much.

If you want an indoor/outdoor highly efficient integrated plenum + fan then look at the Hopsco Airstove ODF1500. It's well built and very long burn times for the amount of wood used.

BTW the J.A. Roby & ULTF is not where near as large and efficient as the Enterprise Faucet 8130 which could take 32" X 17" X 17" logs. It's too bad that E-F burnt down a bout two years ago. No parts left either. PSG did have a line of nice wood furnace such as the PSG 4000 and 4500 which had front top exhaust which gave off much more heat than the current MAX Caddy.





Looking for good /bad information on the EPA "ultimate" wood stove model ULT by J.A. ROBY.Any help would be appreciated.

I moved one of those once. It has a unique look. It's really big but kind of expensive for a cheap stove. I would spend a little more to get a good name brand stove.

I'll clear a few things up here, what your saying is completely backwards. Both Yukon and Airstove are EPA exempt, they do NOT meet EPA requirements. Also the other furnaces you listed that were discontinued by PSG because they were also exempt.

For those of us that have upgraded from a basic furnace (exempt) to a EPA certified unit, there's a huge difference.

Also, how can a company tell someone how many cords of wood they will use a year? It's not easy to calculate, considering climate, square footage, insulation, etc. As far as the spec sheets you feel aren't useful, I've done heat loss calculations on our home, and they are inline with the specifications on our furnace.
 
That is incorrect i verified and the gov won't even allow the yukon or airstove cross the border into Canada if it want's certified aka what you call exempt.

I am not going to argue this point. Also the fact of calculating the amount of cords of wood burnt is done in my region constantly and peoples predictions are over 90% accurate year after year furnace after furnace.

Your more than welcome to go to the EPA's website and view current EPA certified units. Yukon's could not be sold in Canada until they were tested for Canada's UL certifications for safety, which has nothing to do with efficiency. There's too many manufacturers on the market boasting on how efficient their units are, just to find out it's quite the opposite. Woodstove's have been cleaned up, and being a user of a woodfurnace, it's nice to see them cleaning up also.
 
6" flue in such a big stove. Is that a first?

I have a pre EPA Johnson Energy stove (furnace) and it has a 6" flue coming off the back of it. 2 feet away from the 6" outlet I have it going into a 7" insulated SS chimney pipe which is 17' long/high. It's worked well for 30+ years.

My firebox will comfortably accept 30" wood. I cut my wood 24" though, because that's the length my splitter will take.

That Roby stove looks like a beauty queen compared to mine, lol. But my big 'ol box has nice red side panels, a red top, and the front has red trim. I love it. More importantly, it heats a little over 2400 sq ft of living area very well.
