 Thanks for loading the pictures! We are looking at two perspectives of a tube shell gas to water heat exchanger and one of my test rocket/brew kettle. The heat exchanger pictures were taken a couple of weeks ago before the bottom was welded on. That is why on the picture to the right (taken looking up) you can see the 21 tubes (1 1/2" dia.) that the hot gasses pass through for 32" vertically surrounded by water. Now, with a bottom on, I have to unbolt a flange to open a hand way for cleaning/inspecting access to those tubes. The middle shell section is made out of two top and bottom less modern style beer kegs (a brewer's wet dream) butt welded end to end with the tubes passing through. The top (visible in photo if you can make it out) is an older style more round beer keg section and is where the gasses re-unite and exit up through the center of the six inch pipe flange and continue up the heavy pipe stack that the thing is hung from. The bottom section (not visible) is similar but has the gasses enter the side through a 3 by 9 1/2 inch duct in an effort to encourage more even flow thru all 21 tubes. Except for one thermometer port roughly in the middle on the left photo, all of the water plumbing ports are not visible as they are on the other side. These ports include cooler water return to bottom and drain , pressure relief valve, and hot water exit up high. These 1 1/2" ports are sized for gravity flow circulation with tanks above. I plan on having options for the hot gasses from my rocket. Directly up the flue for start up, a 3 ton bench to charge, and this hot water heat exchanger. So far I've been wasting a lot of heat as I haven't built the bench and the heat exchanger is not in operation yet! The rocket tester/brew kettle (bottom photo) is a classic box wood stove that I converted by closing off the original rear smoke exit, cutting and welding in a 6" pipe heat riser on top, insulating with two layers of KAOWOOl, welding on a keg for a barrel with bottom right side exit and firebricking the fire box. On top of the heat riser shell keg is another keg welded that is the 12 gallon brew kettle. I guess it isn't fair to call it a brew kettle until I brew in it but that is what I'll do with it when I build a more substantial rocket. Right now I heat HTF for my hydronic floors( hence the Frankenstein plumbing partially visible!). Does this explain it O.K.?

lol, alright, no problem... I have a million other things to do to pass the time...
But I do need to know by next spring, as I have to change something then. We have a propane water heater right now, and I hate buying propane...
If I hadn't seen this, I was just going to play with the idea of raising the propane one a foot or two and seeing if I could shove a form of rocket heater under it...
