The really heavy alumina kind that hold heat and will release it after firing, and insulating fire bricks which insulate against heat (hold a blow torch to one side while you hold the other, no problem).... The heavy ones are about a dollar a brick (I have used them for brick oven)....the light ones are about $5 (used for the door of the brick oven)Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2686829448547770092.post-5765068507709824762018-08-23T09:11:10.330-07:002018-08-23T09:11:10.330-07:00“This is the difference between a rocket stove you...“This is the difference between a rocket stove you can make a fast clean fire in and be cold between firings (move it like carrying a bucket) and a mass-loaded stove that you make a small fire in that burns for 45 minutes and gives you 6 hours of nice warmth (and a cooking surface for about the firing time) at the cost of being heavier than the rest of the house combined.”<br /><br /><br />To be honest, this struck me as a rather boring topic, until I read pdxr13’s comment above. So I googled (Or rather, DuckDuckGo’ed) “mass-loaded stoves”, and found a few plans. But of course they are far more complicated to build than someone of my motivation and skill set would allow for.<br /><br />I’m thinking that a reduced scale, custom built, free standing fireplace, in a very well insulated dwelling, would be the way to go. To be honest, I hate wood stoves, thus the reason for the free standing fireplace (look them up. The kind I’m thinking of look like the one’s in the link below, but are wood, not gas).<br /><br />http://www.neiltortorella.com/images/free-standing-ventless-gas-fireplace-940-freestanding-gas-fireplace-500-x-500.jpg<br /><br />http://www.accessnw.org/wp-content/uploads/2015/07/free-standing-gas-fireplace-australia.jpgAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-2686829448547770092.post-36656846918944347902018-08-23T05:12:00.889-07:002018-08-23T05:12:00.889-07:00So, really, the rocket mass stove with the cobb co...So, really, the rocket mass stove with the cobb covering the horizontal chimney isn't going to do all that much except wring all the heat out of the smoke. It is much more efficient but not a true mass heater. Wouldn't the cost savings of wood salvage be negated by the truck wear/mileage/gasoline? It isn't JUST labor-more like delayed payment of equipment cost.James M Dakinhttps://www.blogger.com/profile/01382139289994087931noreply@blogger.comtag:blogger.com,1999:blog-2686829448547770092.post-72931623025739431502018-08-23T00:03:17.943-07:002018-08-23T00:03:17.943-07:00The "soaking" of heat is almost a functi...The "soaking" of heat is almost a function of mass. If you have any 100 oz silver blocks, they would do a great job as a heat flywheel while you are waiting to need them for monetary purposes. A couple hundred pounds of cast iron works great and lets you steer the air in/out, but if you want some warmth in the morning (12 hours later), you need to add serious weight that almost only can be rock by the yard and ton. This is the difference between a rocket stove you can make a fast clean fire in and be cold between firings (move it like carrying a bucket) and a mass-loaded stove that you make a small fire in that burns for 45 minutes and gives you 6 hours of nice warmth (and a cooking surface for about the firing time) at the cost of being heavier than the rest of the house combined. <br />I lived in a house with a mass-loaded fireplace in North Seattle. It was cheap to run (a load of mill-tailings every fall) and kept a big 5 bedroom house dry and warm (except for my bedroom down a long hall and over an unheated garage). Very little fuss with the fireplace, less than making breakfast. We could have substituted more labor for money by gathering scrap wood but we had a truckload of short dried mill bits dropped in the yard. It was the city and we had plenty of money in the late 1980's. This house was retrofitted with the fireplace, but the ideal house is built for the fireplace. <br /><br />pdxr13Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2686829448547770092.post-56458600354423827652018-08-22T17:49:29.093-07:002018-08-22T17:49:29.093-07:00A timely article.

I'm in the process of building a two-pot-wide (maybe three pots if set together like a triangle) rocket stove out of landscaping blocks (in a circle) and plan on a firebrick liner in the center, secured with refractory cement/mortar. I'm trying to figure out if or how I can make a meat smoker to the side for a cold-smoke with a little chimney to divert the smoke. The connection from the rocket stove to the smoke chimney wouldn't be airtight, so that might be a problem. A hot smoke cooks the meat for use right now, a cold smoke preserves the meat for later storage where you have to cook it again before you eat it.<br />Peace outAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-2686829448547770092.post-14472835362924105002018-08-22T17:01:33.940-07:002018-08-22T17:01:33.940-07:00Thanks to anon for getting you the start to find t...Thanks to anon for getting you the start to find the video.

The point of fire bricks is to keep the heat concentrated in the burning chamber to get a good hot burn, making less smoke/soot/creosote and getting more useful heat from the fuel. <br />pdxr13Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2686829448547770092.post-69210560613745987992018-08-22T14:33:30.624-07:002018-08-22T14:33:30.624-07:00See my reply above to 8:53-there is the vid I was ...See my reply above to 8:53-there is the vid I was talking about.
