I am not a batch box expert but I just feel that raising the steel even 3-4” might make a more even temperature on the top of the dome and may also offer other benefits without changing the whole design.

Though it's tough for me to settle knowing what the problem is AND how to fix it lol, my goals were to replace my old wood stove with one that was more efficient, heated the house for longer, while still looking aesthetically interesting. And I've accomplished those Sometimes you can't quite have the ideal, but what you've built does a great job at ticking the boxes and I bet you've enjoyed the learning along the way! |

Had an idea to surround the sides with some rounded pavers to add some more mass. It's working really well! Added a little over 500lbs dry stacked.  The flue next to the tank really helps with draw. Did have to turn the T slightly to accommodate the pavers.  And the new front view: I tried road chalk on the front to make a little Christmas decoration but I started to smell something funny coming from it so had to wipe that off quickly. Unfortunate, but maybe there's another medium out there that will take well to heat and still come off easily. I also found a way to insulate the door in normal use, but it can be taken out easily for viewing.  |

I also found a way to insulate the door in normal use, but it can be taken out easily for viewing. Looking good. Be careful with insulating outer parts of the stove, though, like the top part of the steel bell or the glass in the firebox door. Putting insulation on the outside of those parts will cause them to accumulate a whole lot more heat than they normally would experience, and may get hotter than they’re able to withstand, undamaged. Normally, the steel conducts heat to the surrounding air, (cooling itself off) ..and the door glass allows infrared spectrum / radiant heat to pass through it without accumulating in it. ..just don’t want your steel to deform (or gradually burn through from the inside-out) ..or your glass to crack from the heat build-up under a layer of insulation. It can get surprisingly hot under there. |

Thanks. I'll keep an eye on the steel, but the insulation is on the inside of the glass. There are two removable decorative prongs that are able to hold a sheet of fiber wool in place. Just pop out the prongs and remove the wool if I want to set it up for viewing.

Here are two posts which explain how hazardous it is to inhale ceramic wool (even the "bio" one) and how flames degrade it.
You could replace the ceramic wool on top of your barrel by bricks. it could make a nice arch.

Hmm, I definitely don't want to mess around with carcinogens. I'll take off the wool and I'll have to do some thinking about how I want to capture the heat up top. Thanks for the info fiedia
