9876543212001: Nice job tryin2hard , enjoyed.
Alex Morlina: Kick start this... How much?
Michael Steinrok: If that is the result of you being in a hurry, I wonder what it would look
like if you had more time? LOL. Seriously very well done. Any stationary
engineer will tell you the sign of efficiency is no smoke from the stack.
Steam engineers too.
kenny johansson: was there a fryingpan at the top ? great tips . wonderful job
ilililhy1: I started Researching Rocket Stoves and Heaters and now I have started
building one,this will be the furture of the heater and stove.everyone
wants to put out more heat with less fuel.Nature
Gas,Propane,Kerosene,Electric,Oil and so forth, keep going UP,UP,UP.and
wood?go cut some.Have you ever been in the woods smelling the outdoors and
on a spring or fall day cutting firewood? WOW.Labor of Love.
Alex Morlina: Kick start this... How much?
Skibop dabop: whats in the tank then?
tryin2lhard: My pleasure, what started out as a dire need for heat has become something
quite fun. Thanks for commenting and have a great week.
tryin2lhard: @SPEKERDUDE Great observation, that is exactly what it is, I knew I wanted
to use some kind of steel for the top and was in a thrift store one day
while thinking about this and thought it would be cool to use stainless
steel, I had picked up this steel frying pan and the bottom was a quarter
of an inch thick! Done deal! and now you see it on top of my rocket stove
heater which is producing 78 degrees of heat while it is 36 degrees outside.
David Rymer: great idea........I worked on something similar I would like to privately
email you about.
seafront1: Amazing, tiny pieces of sticks. Burn so clean.
tryin2lhard: Thanks for the comments and as well the enlightenment of the condensation
deal. This has been a great deal of fun and learning for me.
tryin2lhard: Thanks so much John, this was something that was developed out of a great
need for us which I have now taken on as a passion to develop other ideas I
have for a small compact wood stove heating, there are a few people that
are collaborating on ideas to create small stove that has a very little
footprint with a great deal of btu output. There are some very ingenious
folks developing heating and cooking ideas, all open source.
tryin2lhard: @MrDaverrymer I had found the following build by another fella that used a
water heater for his, mine was built from a small propane tank. The way my
stove is put together is pretty much the same as the one in the following
link. I cut out a stainless steel bottom from a frying pan and cut out the
top of my propane tank and welded it in. When I can get a breather I will
take the time to put up a video with photo shots of each step of the build
which will make it quite easy for someone to make.
tryin2lhard: @cdimmm I did take into consideration getting to the inner chimney to
clean, what I did was tack weld the bottom half to the top half and then
used some high temp putty to seal it with, the stuff seals up rock hard
with no leaks, as well one could use high temp silicone, this way I can
cut the spot welds and take it apart quite easily. As well I am making the
external chimney in three sections that slid together and will be sealed
with high temp silicone.
tryin2lhard: Thanks for the comments and tips, I may make myself a camera stabilizer,
its a cheap flip. You can do a google search on wind proof chimney cap,
there are two companies that make them.
jpcelts: Great design overall ! I'll be doing something similar on my boat. Thanks
for the vid.
tryin2lhard: This is an update to my burn times, with dry alder I was getting about ten
to fifteen minutes with a wide open burn, since I installed my flue damper,
and as well by placing a steel plate up top and adjusting the air flow at
the top of the feed tube, along with adjusting my flue damper I was able to
get a 37 minute burn time for my first test run with the same wood. I use
3/4" round sticks about 8" long. It is 36 degrees out side and 79.5 degrees
inside. This is very exciting.
deltafour1212: You think it would get hot enough to use as a sauna stove?
John McDonald: That is really impressive - great job and thanks for posting! Q: What is
your investment in materials - I realize sweat is invaluable, but if you
could provide a costing of materials? Thanks again for sharing, I would
purchase one as I think that much of your work!
tryin2lhard: This idea actually came from the Chineese and Romans, they used this
concept to heat the stone floors by running the fire under them. This is
where we got the idea, it is not new, but old concepts that have been
re-purposed. I got the idea from a fella named Rob who used a large water
heater tank. I will be doing a complete modification this summer on it that
will change the way the fire is fed as well have a glass window so we can
see the fire. Thanks for your kind words.
Brian Martindale: is there a reason the chimnet comes out the side instead of the back?
michbushi: Very nicely done! One thing, water coming out of the chimney, it will
always be there, actually H2O (in gaseous form, i.e. steam), is one of the
products of a clean burn process, and when the exhaust gases hit the cold
chimney pipe, the steam condenses into the fluid form. This is just normal
evan h: Really like your R-Stove design. Perfect size for an RV or small home,
cabin etc. You could then plug this into a thermal mass venting system
installed in a home to store some of the heat. Stainless steel is the way
to go but I'm sure that would be very pricy to get tubing that large
tryin2lhard: If you take a look in my description just above here, I give credit to Rob
at I will try . org. He does get into the science of the rocket stove
science, as well you can find great documentation on the net just by doing
a search for rocket stove mass heater, this is not a mass heater but the
idea and design principles were taken from the mass heater design. I will
be doing some modifications to my stove this summer please see the video I
posted of the mods I plan on doing.
Dan jensen: Contrags, i liked you clip.did you make som drawings on your mini rocket
sove heater. Iwas thinking of making one for my fathers cabin.
rzuchinski: @tryin2lhard My thoughts were to maybe clean out the ashes by capping off
the opening and blowing the ashes out the chimney with an electric leaf
blower or exhaust from small shop vac hose. Maybe you could weld near the
bottom a 'capped off cleanout port' at a tangent and on clean out days
uncap it and force blast air thru it and it will swirl the ashes out the
chimney with a 'vortex' like action~~!
Siskin's Bits and Bobs: The eagle has landed. :)
zapoman27: Dear Sir: I would like to know the physics of this system specially related
to the flow of gases because in this case the chimeny is not in the upper
part of the heater as usually.It s not easy to understand for me. Is there
any bibliography you know for this kind of heaters? I think yours is a very
good projet,so,congratulations. Regards
phantomcharger: subbed, I'll be waiting on that.
alanesmuymacho: Pardon if this is a dumb question, but can you cook on top of it?
Alex Newton: nice stove/heater looks really solid and professional /the only cosmetic
winge i would have is the stand looks a little bit out a place is the stand
although looking well made its just the stove looks a little bulky on such
a small stand but apart from that love your work it is excellent and thank
you for sharing
tryin2lhard: @rsjojo I meant to say I filled the tank with water several times after
removing the valve and emptying it several times, the water will push out
any remaining propane.
tryin2lhard: If it hiccups I just slam it on the back a couple of times:>) I am just
kidding, the air to fuel ratio is enough that the stove burns smokeless, I
would think that is enough air. Thanks for asking.
Judge_Jon: @rdx506 that's exactly what the stove in this video does. Below the fire
chamber on this design is actually facing up. This is a rocket (stove)
heater which is J shaped not a rocket stove which is L shaped.
beachfiredude: right on thanks
tryin2lhard: I forgot to tell you I do have a video up of the build of this stove, the
firebox on this 4X4 inches, with a 3 inch updraft stainless steel tube,
take a look at my video that show how I built this.
paarek: good job
tryin2lhard: @symbolsandsystems Once I have the Rv up to a nice warm temperature I will
cut down on the oxygen feed and as well the exhaust using a flue damper
which gives me a consistent thirty minute burn time per load of wood.
Running it full open throttle gives me about a ten to fifteen minute burn
time, I have not intentionally timed a full open burn yet, will have to do
tryin2lhard: Thanks so much, I am just glad it worked out as well as it did, we were so
desperate for good heat, and just plain ol poor folks.
zapoman27: Hi there: Is the combustion chamber made using two pipes isolated inbetween
like a classical rocket mass heater ? Thanks and regards
tryin2lhard: Actually there is a secondary burn taking place in the insulated pipe so I
would say yes it does matter, I have been told it gives you a two percent
more efficiency burn rate if this matters to you it does increase the
efficiency, I am thinking any gain I can get on efficiency and combustion I
will use it. I know some people do not use the insulation and I think it
takes a bit longer of time to get up to the higher temps for the secondary
tryin2lhard: That is what I said when I found Rob's stove:>) The eagle is flying in
another direction now:>)LOL
tryin2lhard: @deltafour1212 Yes this would be more than enough to get a sauna hot as
well not only for a dry sauna but as well a steam sauna. I would be sure to
install a fresh air supply from outside that would come directly under the
stove, some think that installing it directly to the stove would be better
but this creates a danger of a reverse draft and turn your fresh air into
the chimney, so it is best to have it close to the fire box and not
tryin2lhard: @dontlikenumbers Thanks, Wire feed welders these days are pretty cheap, I
picked up a used Lincoln 110 volt for 175.00 Thinks are so tight
financially I had to buy my equipment a piece at a time.
tryin2lhard: If your talking about this heater, I have not done any drawings, I plan on
doing drawings on this stove with my new modifications. I put in a much
larger firebox, with this configuration I was only able to get 45 minute
burn times and that was a stretch. Now I can get over an hour burn time,
and with one presto log a three hour burn time.
Saeid Momtahan: Hi. Been looking for more info on that chimney cap that you 've made. But
no luck! Can you post some links to more info? Great set up by the way. The
only thing I would suggest is when using a camera with a fairly narrow
field of view, step back as much as you can and point to what you're
talking about. When you're so close up to stuff, they start looking like
abstract art. Also if you step back little, hand shakes won't mess up your
video as much. A camera with 28MM eq. lens would work well..
tryin2lhard: No it is just a single pipe that rises on the inside of the tank, take a
look at my video I have up on the step by step build, you can see the inner
burn chamber in the photos I provide, I did insulate the the three inch
stainless steel tube on the inside.
tryin2lhard: @rdx506 Actually I now remember doing some research on this, and if you
connect a cold air source from outside to the air inlet for air fresh air
feed, you can had your draft reverse itself and create dangerous back
draft, in where your fresh air intake can become the chimney. These tests
were done by a reputable company and found they if you brought your fresh
air from outside and set it near the intake this was a safe way to do this.
cdimmm: pretty slick, do you think there will ever be a need to clean the inner
chimney and if so is there a way to get to it?
