I mesure 400°C min 30cm above the HR. Your 150°C seem quite low.
You put your hand on the flue. Is the pipe insulated with mineral wool between two stainless skins? In that case, the outer skin stays usually cold. In case it is not insulated, it is a source of condensates.
That seems quite a difference in temperature, but I do have a large gap between the HR and the top of the barrel. Also that particular thermometer is mounted in an axial line directly above the firebox. I don't know if this would disrupt the gas flow to any extent, but it's possible I guess. The flue doesn't have any insulation. It's just a single skin flue from the heater through to the outlet in the roof. I'm currently in the process of building and installing a drip catching system to contend with this. I'll post some images when complete. |

I saw also quite a long horizontal pipe under the roof. it slows down smokes and cools them much more than vertical pipes. With single skin... smokes get probably too cold and water condensates.
May be you can also try to insulate at least this part of the flue and see if you get less water.

Yes that could be an option, but I've come up with a solution to catch and redirect the drips. I don't mind living with the condensation as long as it's controllable. |

I have a steam punk themed party house, I have used titanium exhaust wrap to cover my chimney pipe.
It looks cool and seems to work very well, perhaps you could try it out as it is fairly easy to fit around an existing pipe.
i started off with one wrap but i now have three thicknesses keeping the pipe safe to touch, it comes in red black blue and olive.

That sounds pretty cool Martyn, love to see some pictures. I'd never heard of this stuff. Found this image, but haven't come across the colors yet.  Sorry for the delay on this. Only just realized you posted it here. |

I've finished all the plumbing for the condensation drip collection. I have this plumbed together and down and out through the floor and have it hooked up into the waste outlet.   I also made some fairly significant changes to the barrel clamping system. In the initial design I made the false assumption that the whole system would heat up fairly uniformly. This is not the case. The clamping bars around the circumference stay a lot cooler than the barrel itself. This of course creates stress in the system due to the differential in thermal expansion. I've installed 48 stainless steel compression springs at the bottom and top to absorb and control this movement. This is working quite well  |

Gotto imagine you are gonna have to clean out that trap once a season because it will become clogged with tar...
I wanna see the supports in the basement/crawl space that hold this monster UP!

I have never managed to find an easy way to get photos up on this forum but you can see my party room at the beginning of this video…

You could be right with the clean out. I'll be taking the bottom flue outlet off to have an inspection when the weather here picks up. That will be interesting. I haven't got any pictures of the under floor footing structure, but it is very substantial. There's one main reinforced concrete pad footing and 3 other smaller pads on a 2 metre PCD that I've used for triangulated bracing. I had to include multiple jacking points to plumb the unit once it was assembled. |

The floor tiles were just pieces of vermiculite so easily replaced but during the life of that particular stove they were fine and showed no cracks but I did coat them with water glass.

Well I also enjoyed the vortex display but unfortunately the fire did not really suit my needs … that is not to say that Trevors design is not a brilliant one as his own tried a tested version can easily justify. I did not follow his design exactly, especially in the materials department and the stove proved to be to fickle for my use. You can find Trevors detailed and comprehensive thread here donkey32.proboards.com/thread/703/vortex-stoveI reverted to my old design vortex J tube as this style will burn virtually anything and is very controllable for cooking and space heating in my outdoor party house. I have a thread here … donkey32.proboards.com/thread/3812/vortex-tube-update?page=1&scrollTo=36519 |

I like the idea of the safety mesh to protect the glass. I should do something similar with mine. |
