Hello Trev,
I have been following the thread and have read the whole discussion and i decided to build a Stove in my children room with this fire box for heating. I would love to show you. It works great, and with only one load there is Nice and warm for 24 hrs. Thank You for all your hard work on this and for sharing IT here.

How could I send you photos and videos, I can't find an option here. I could send it to you via whatsapp or e-mail maybe?

I sent you an PM with my email address yesterday (at the top of the page click 'Messages')
When I receive them I'll upload them to my server and post them here. The forums own picture hosting is already full.

You stove looks good, more pictures and a video would be great? Hello Martyn, thank you, indeed we like it, and also works good thanks to all off your hard work on this type of burning system and sharing it here. A video should be coming soon, I have uploaded one on weshare. |

There has been some discussion relating to the Vortex Stove on jonasp 's thread here: donkey32.proboards.com/thread/3995/vortex-stove-175mm?page=7&scrollTo=39368so I wanted to copy it here so it's all in one place and it doesn't take over his thread. Secondary air on my setup turned out to be a complete waste of time. It initially looks like it works, but if you watch the fire for more than a few minutes after, the firebox gradually gets more smokey, and the amount of secondary air the afterburner needs gradually increases, as the more secondary air you give it the less is drawn in through the primary and the less complete the initial combustion. Following on from martyn's experiments late last season with a larger top chamber ( www.youtube.com/watch?v=YN_jaVxu3cw&t=10s ): My experiment yesterday was just the removal of the left-hand side of the top chamber, so that the top chamber width was expanded from 280mm wide to 540mm wide. The top chamber exit was then formed by the approx. 1.1 csa gap between the internal chimney and the front of the stove. The 'fold over exit' from the afterburner into the top chamber remained unchanged at 1 csa. Today I removed all the vermiculite boards from the top chamber so it was maximum size (540 x 400 x 115), the height expanded from 65mm to about 115mm, and I reduced the exit from about 1.1 csa to exactly 1 csa. The weather was very windy and I loaded a normal batch of wood. The vortex was very nicely formed and the fire ran well, it briefly overfueled at the peak but nothing I wouldn't expect with the strong wind. I will run it the same again tomorrow, hopefully with less wind and see how it goes.     Trev |

Very interesting that such a huge change had so little effect on performance. I suppose the question now is would the effect be the same with a Vortex core in an open bell, or is your labyrinth channel mass now having an even more important restricting effect to regulate combustion... I think attila's Vortex core is just in an open bell, which is just a few posts above farther up this page. |

Sorry if I was unclear, I was wondering about how the larger top chamber would fare in a bell, not the Vortex in general. If you get the chance attila, I'd love to know some dimensions or see a sketch of your heater- beautiful shape and proportions. It still feels like early days and all results help build the picture! |

I did try quite a few variations to the theme, this one started off OK then went a bit wrong!

Thanks martyn, that's a great video, I must have missed that one before. 1:00 to 1:20 secs is one of the best demonstrations of how resistance works that I've seen.
