    I read BrowningBAR post below and he actually reported his stove top temp and side wall temps. Ive been curious about other stoves Top vs Side temperatures for a while now.

    I know stoves now adays are designed for tighter tolerance installs, but in applications where you dont need tighter installs, increased side wall temps in my opinion may provide better effeciency ( in regards to getting heat inside the stove transferred to the room).

    Ive been running my Osburn 2400 for a few seasons now, and the stove burns well, keeps the house warm, but It doesnt seem like I get any/much heat off the sides. I measured it tonight and with a crusing stove top of ~600F my side temps measured ~300F.

    Im really curious if other stoves have this type of top to side temperature difference.

    If any Jotul F600, VC Defiant, Englader 30, Blaze king and SoapStone owners could post their stove Top Vs side temps or observations, it would be helpful and interesting to compare.

    thanks again to this site and all its knowledge.

    Mine runs very close to each other in temp.

    My free standing Century stove was 567F on top and 375F on the sides - as shot with the Centech IR gun.

    In all the stoves I've run, the top and front glass are the hottest (not sure how accurate glass temps are, but there is no mistaking the glass throws a lot of heat at times). I'm also running a Defiant and an Encore. On a high burn, the stove top on the Defiant can be 650-700 on the griddle, 500-650 on the top casting around the griddle, 650-750 on the glass, and the sides of the stove will be 400-500. This is about the same for the Encore.

    I haven't run the 30 enough to know if the side temps on a high burn at this point are consistent, but when I have had the stove top at 700-750 the sides seem to be in the 500-550 range.

    The Hearthstone Heritage would be 600 on the top center stone, but as low as 400 on the stones to either side of the top center stone. The side of the stove would be 300-450 during that point, depending upon where you are taking the temp.

    The Vigilant, when it was in down draft mode, would have its one side panel nearly as hot as the top casting at times since a lot of heat passed by that side casting. The opposite side would be less hot.

    All temps were taken with the same IR gun, a Kintrex.

    thanks for the responses guys.

    I was bit suprised by Coreys response on his magnolia. A steel box stove that radiates off the sides well.

    sorry I hit the repost too quick.

    I guess the magnolia behaves like that because it doesnt have side sheilds? (from the images that I have seen)
    Looks like the defiant is similar and very uniform over the entire stove, Is this the design orthe cast iron effect?
    The other box stove comments seem to be on track wiht mine, but the top to side difeences ar dictated by the amount os side shielding ( makes sense)

    I was supprised by the soap stone, I would have thought that to be much more uniform. It seems like my stove has a similar hot spot in the center and tails off to the edges and sides.

    Ive been thinking about swaping out my stove with a F600 or defiant, but havent been sure if its worth the hassel and if I would see/feel a noticable difference.

    Any Jotul F600 or Blazeking guys want to chime in?

    Besides the side shields on the outside of my stove, Blaze Kings have shields on the inside as well. I've never burned mine without the outside shields, but I'm sure side temps are significantly lower. The wood in the rack 18-20" away doesn't feel any warmer than room temp.

    There aren't any side shields on the 30.

    On my Super27 (with side shields), I can actually touch the sides with the top at 500° (not for long, however;))

    Does it have half shields on the sides or is that an option?

    My Napoleon side temps were much lower then the top, the Englander 30 as BrowningBar says is about the same side as the top which for my application is working a whole lot better. Our living room where we spend most of our time is off on the side of the stove.

    I've watched my side vs top temps quite a bit for much of the same reasons that the OP shared - I figure the whole stove being hot will heat the room more than just the top.

    At any rate, with the FV I found that during the primary burn when the cat was most active the top would clearly be significantly higher with the sides often times only 250-300 (or lower even). However once down to coals if I pump the air up a bit the box would be much hotter as the coals would burn and radiate more but the cat really had little to do. And as has been shared in other posts, with the FV you can get more overall heat sometimes by adjusting the air to get some flame in the box while still feeding the cat well enough (vs a dark 'cat only' burn).

    What I've found interesting about the PH is that the sides seem to remain more inline with the top temps. Mind you I havn'e yet mastered really long burns so perhaps it is excessive flame in the box causing this situation.

    The way I look at it, hot sides do not translate into more efficient heat transfer per se. It's just the difference between a convective and a radiant design. If you burn 20,000 BTU of wood, then what doesn't go up the chimney is going into the room somehow, whether it's predominantly radiant heat or convective (heating the air). And that's a matter of preference and need. Some folks love the radiant intensity, others the softer radiant feel, such as from stone or cast, and others a balance of radiance and convection. Of course, there is the clearance issue as well.

    Just from the website, That Osburn looks like a nice, balanced, convective/radiant design.
