Thanks Glenn!!

My lack of literature on design concepts for the bell is making the idea risky. My application is so niche I'm concerned to be designing myself without an expert on hand(any volunteers?. I also don't have much time to come up with a different plan. I have 2 55 gal drums. Can I use one for the rmh and pipe it directly to a second "settling" barrel, that is barely nudged into the baby barn, and then exhaust the remaining heat through a short bench to finish exhaust out near the first barrel?

Do you have a suggestion for resources?

Should the second barrel have input in top and cool down (exhaust) near base? Does 8" pipe still work? How do I even work this mathematically? I am a business so the pressure, of performance, is on! I feel confident in being capable of cutting a circle in the barrel and using metal heat "cement" for sealing the input/output of the second barrel. I do see the reasoning for your suggestion and am just hesitant due to more unknowns.

The heat barn is going to be VERY insulated and lined with reflective material. The only airflow to and from the heat barn will be when the door is open and when the vents, that we connect the barns to are open.(we were planing on cutting those as we got a feel for output of heat and how responsive each barn is.

Another note: I will use cinder blocks spaced 6" apart as base for the pallet, used as floor for heat barn. These pallets were used in commercial HVAC unit transportation and are rated for 10,000 lbs.

I would be willing to spend a little money on a custom design or a proven concept. Although, our budget will never have enough room for the invaluable information I feel I've already learned!! Your experiences are priceless! I enjoy this adventure and can't wait to find a solution for our quail barn!

Thanks!

Ok! I've been doing a ton more research and have more ideas to run past you guys!

Decided to go ahead and do a RMH vs a bell. A ton of reasons for this but the biggest is length of time a mass will radiate heat. I need this mass to stay warm for a long length of time(overnights plus some). This will be a 4'x15' space that is going to be consumed by the heater. This space is between two barns and will have vents, located near the top of the walls, to each barn that can be closed or open. Organic venting will hopefully be enough to raise the temp. I understand the heater room is going to be insanely hot. the only reason to go in there will be to feed the stove.

What do you think?

Also, my plan is to brace heater room off ground(need to avoid moisture and elevate to barn floor height)... Placing cinder blocks on ground level, then using some commercial pallets(2x6 construction) to form the floor. Then laying down 1/2" plywood(the pallets are almost solid along the top and bottom already). Using misc bricks I'll outline the shape of my core and put a mixture of perlite and clay directly on plywood to insulate. Pack this down? Then add a leveled sand, less then 2" thick. Then place firebricks for my core and riser. Insulate entire thing with clay perlite allowing for clearance around riser for airflow and 2" clearance from top to interior barrel. I have a barrel with the removable lid, what's your experience with them? Worth using for clean out? If so, just cut off bottom?... How do you transition to the 8" piping? I found galvanized 8" HVAC vent that was angled and could be built up and insulated with firebrick and perlite/clay. Worried it might collapse over time, what are the chances if it's properly built up with firebrick and clay/perlite? Found single wall stove pipe that I'd use for the first 48" into mass, to withstand the heat, then probably switch to galvanized pipes, "t"s, and elbow. For roof vents, does anyone have a preference? I found 8" galvanized that's used for simple roof vents but it'd be an almost flush mount with the roof. My roof is sloped galvanized. With my barrel being 2" from my exhaust pipe, do I need to worry about elevating it above the peak or anything? I, obviously, want to avoid back draft as much as possible.

Sorry to make this so long! I'm excited to get started!! I have 90% of my materials!! Then I want to help a friend build one in her greenhouse.

Interesting idea, Glenn! I spent the last few days looking at concepts for the bell idea and was thoroughly impressed. BUT it brings up even more questions

First, I'm working with a space that is only 6ft high. I'm short so this won't be an issue of clearance for me but may be an issue getting the height to generate enough btu's and then encasing some in mass.

Second, if I stuck to the initial siphon barrel and vented(&insulated with mass) from my core to a second barrel located in 1 barn(3-4 ft distance), then did a cold air return back through mass and exhaust through roof, near first barrel is it hypothetically possible? I understand there may be a ton of variables. One of my concerns is physically cutting into the steel barrels (I only have a hand-held metal wheel grinder) no plasma cutters here!

Lastly, the baby(brooder) barn is my biggest concern, (the babies need heat and we've been a spending $100's of dollars a month to electrically heat with heat bulbs. I will still need bulbs to regulate heat but can hopefully lessen the burden.) running a barrel into there, and using mass to help prolong the radiant, makes a ton of sense to me. Hopefully there's still enough heat to run back through the stove!

It could be like a combo bell/rocket heater! Ha!

Also, Any suggestions on free or cheap programs out there that I can use to illustrate my current setup and idea? If not, it's pencils/paper and .jpg uploads for me!

Thanks Glenn!!

I was hoping to use it in insulating the riser along with vermiculite or perlite.(I found non-asbestos vermiculite but am having difficulty finding perlite) I also found some fire bricks that I was going to use for my core. The property we're doing this on has very fine sand on it, should I even attempt to use this instead of sand, along with clay and straw, for the thermal mass? My concern is the sand is almost clay-like itself.

I'm leaning towards the thermal mass being bench-like but running the tubing vertical on itself instead of laying along the floor horizontally. If that makes sense? Basically it'd vent (with stove pipe for the first 10 ft) from the barrel along my insulated floor and then I'll brace it through two turns(180*) back up on itself and vent through roof near barrel. Not sure what I'll use for bracing structure to test the unit but will obviously be adding thermal mass between the two levels. It should be tall and thin!

My thought process is, the mass will radiate through the plywood barn wall and organically heat it.

I found 900 lbs of Georgie's clay. Wow! I'm excited to put it to use! Any recipes with clay for insulating the heat riser or thermal cob for the duct?

Hi guys! I'm a complete newbie in this area. Very interested in heating my quail barns with clean, renewable, energy. I need to know what material really withstand the test of time? I see a ton of rocket mass heaters that use differentmetals, concretes, and perlite. Most of these burn off. What doesn't burn off?

My idea is to set up a "heat room" that connects my two barns(4' of distance) with a gutter(rain collecting system) and roof, along with a front door and rear venting. My goal is to generate enough heat to cleanly heat both barns(both are 12'x 24') with a fan driven duct system. I need to keep the baby quail barn 70* and the adult quail barn above 45*...

I'm leaning towards the following materials; firebrick, cob, duct.

We have clay soil that is super hard when dry but quicksand texture when wet. Really looking for proven design concepts. Because there's an earthen floor I'm looking for ideas on providing a flood resisted barrier from the ground, as well. Would LOVE some feedback from all you seasoned folk!! (We're in Cashmere Washington and would love to extend housing for experienced help option!!)
