Im a new home owner doing a big renovation. I'm planing to install a solar place and water heater but wood fire would be awesome for heating in cold winter, cook, and help the solar system with water heating.
Today I removed the lower part of the flue (it was not classy, too big). The upper part remain (the one between the ceeling and the roof)
I love the look of the walker stove / vortex stove but the overall design seems too experimental for me?! I really don't want to spend time testing and tweeking the stove, I already have so many things to do... So Im planing to convert this fire place to a batch rocket. It seems well tested.
I have many questions and will do a sketch so you can tell me please if my idea seems ok Cheers
Above the riser I would like to install a ceramic glass cooktop. It is based on a (4 or 5") batch box, so I can keep 30cm room between the riser and the glass, but maybe 4-5" batch box is too small for my home?! I would like to add an oven door on the front opening. It's a double bell design I belive, not sure if it's a good idea?! I haven't calculate the ISA yet (should be around 3m²)
not sure what would be the hole size from one bell to an other. Also what should be the diameter of the flue.... many questions, but it's too late for me time for a sleep! Cheers

I can't see your sketchup files, since they're saved in 2016, and 2016 sketchup doesn't work on my computer.
With what you have there now. I would make the firebox sideways in the actual fireplace's firebox. But there's a problem, the stone (pierre du gard) on the right is too thick. I would cut it out, just enough to accomodate firebricks. Rest the bottom of the riser on that woodrack shelf where the bottle is. Build a first bell around. Quite high, And may be extend that bell on top of the actual fireplace, so you can make an oven on the side of the heat riser. A black oven in the bell. With a slot of the right CSA at the bottom, which would pass under the cooktop, rested on the fireplace's top. On the left hand side towards the fridge. Then go back up with a tiny bell, which would look like a chimney, and a plunger tube inside. I have it drawn somewhere pretty much. But i'm late. I'll take care of this later.
ISA (floor not included) is about 1.93m2 for the first bell about 1.98 for the second one I can reduce that surface with a couple of bricks (raise the floor level) or do a single bell (remove the stone between the first and second bell) Im starting to read ianto and leslie book about rocket stove so I can gather a couple of tips and answer some of my questions
Well, i see. 4 inch is suficient for cooking. Good for heating. Tho, not for a great surface. 40m2 if well insulated. And in your options, there is a problematic one. The firebox on the floor. Try to kneel to light or feed. My range, at 30cm from the ground is bad enough already.hth
I will go with your design, but I have so many questions
I'm wondering if the simmering plate will be hot enough for cooking? it sit on the top of the second bell which is the coolest I belive. Also I would like to connect the stove a solar place and water heater I'm planning to build. I think that a copper coil sealed inside the second bell would do the job. I have to check if it can work
I would like to start in about 10 days.
I have a retired builder (maçon) willing to help me, it's gonna be easier
I have to source : -doors -pipe for the chimney with bracket/adaptor (diameter should be 150? It should suck down low from the second bell up to the roof I belive) -brick for the riser/batch box (Online there is this boisseau de pouzzolane but it's too big! I have no idea to source the parts you used in the sketchup file) -brick (refractory for the first bell, regular for the second bell?) -I think I will use this mortar -steel pipe for the secondary air -copper pipe?
Well, for the firebox and riser, you will have to addapt. Either cob for the heat riser. Or order insulating firebricks from prosiref, which is expensive. Or look localy, i bet with salernes and grimaud not far, you can find a brick or tile factory, which could make you some tubes or other elements for your rocket. Those chimney ellements you're showing are no good for a heat riser. Even what i use is fragile.
Doors, best bet, leboncoin, buy an old stove, or chimney insert to scavenge the fascia.
For the brick, go for all refractory if you can, they store more heat.
I was checking leboncoin for bricks. Ouch, they think they have a gold mine down there.
www.leboncoin.fr/bricolage/1025298586.htm?ca=21_s Too expensive. But if the guy needs the space and you have enough for your build, he might take 500. I paid 200 for 2.4 tons of clean oven bricks, plus chamotte and mortar. Some slabs etc. Don't be shy to make him an offer. There's not that many people building bread ovens anymore. So not that many wanting these.
If you're feeling tough, there's this one to dismantle. Tho, i don't know if there's enough bricks.
martinm: any one here with info \ experience with heat (from a mass heater) distribution with ducts throughout two storey house ?

daniel: in my experience as I am working now on something of that nature, I have thought of making a heat exchanger and distributing the heat through vents using a slower fan. Now after a few years I realize that mass heaters give out primarily radiant heat, for

vesuvius: Do any of you have experience with using the glass from home oven doors on a rocket stove? I'd like to have a viewing port on my stove but don't want to fork out for new ceramic glass. Any thought as to whether it would take the heat of a rocket stove?
