They share the same listed dimensions, so I thought I would ask.

The fire box is bigger on the MKIII IIRC, yes 3 grates.

Dimensions are different, from what I can find -- the Mark III is deeper front to back to accommodate an additional grate, and stove weight is 80 pounds more. See here -- older web link: http://www.noutilitybills.com/heaters/c ... ation.html

The Harman web site seems to have dropped references to the Mark II. Only Mark I and Mark III are shown now. The install and owners manuals available from the Harman web site only describe the 1 and 3, even though their title still includes 2. Is the Mark II no longer made? :?: :?: :?:

That's because they no longer make the Mkll. All 3 of the MK stoves are basically the same stove just upsized.

I don't have the fire box sizes commited to memory but I believe they are 48k, 72K and 96K. The MkI has two grates as does the MkII. The MkII is wider than the mkI. The MkIII has 3 grates.

Ah, I see now where I missed the depth difference when I was comparing them on the Harman website.

well that's all that matters then...who cares what the grates look like ? It could have no grates, if the BTU is 24K higher, it's higher. That's more heat.

Along with dumping the Mark II, I believe they are only
offering top flue models as well.

It almost seems as if Harman is weening itself away from coal. Their parent company, 'HNI', located in Muscatine, IA (and not in China as some have suggested) seems to be focusing on pellet stoves.

Yeah all 3 stoves look identical, but they get progressively bigger. Each one going up to the Mark III has more firebrick and a bigger firebox than the other, and as stated an additional grate in the Mark III.

If top vent was all that was available when I bought either stove, I'd have passed and looked for something else. The design of the rear vent seems better for efficiency, IMO.

Won't be buying any Harman products again anyway. Already got what I need, and thankfully before they got bought out by that company that I'm not too thrilled with thus far ...

If you look at the prices of the good pellet stoves there more then the coal stoker stoves because there "green" and right now if its green it costs lots of green(as in $$$) so the profit for them is very good and the market for coal stoves I'm sure isn't real high.Keepaeyeonit

I agreed that Harman is "weening itself away from coal." Northern VA actually has a Harman dealer but that dealer no longer offers coal stoves on the floor. Oh, they will support my stove but everything has to be ordered. Lisa
