Fan crapped out.i knew it wouldnt last long cause its an old one i use to use to suck fumes away while welding galv metal.and im thinking now the clay and brick i encapsulated the copper coil with ( trying to create a mass that would stay hot and even ) is actually blocking heat from the all the heat from the barrel from heating the copper as well. If i take the clay and brick off i will also have a smaller riser to help with my draw issue .since ill have to pull the barrel to make a better horizontal transition anyway ill do it then and im glad i used more of a cob mix instead of mortar. Another thing i noticed is inbetween feeding the fire the heat slows big time and the still cold water from the tub starts feeding back into the outlet since it is submerged .might elbow up and out so it wont back feed cause once it cools off it takes forever to heat again .mainly just not hot enough even pumping water through the coil slowly .as far as the stove it works well with a few mods it should work great! I might just use it as a heat source for a pizza oven and build another set up closer to the tub if all fails .also i will do a bigger system

I guess 4:00 am is the only time i can post a pic.everytime i try it just goes to a page no longer available thing then loses everything i wrote .whatever, i hooked the inline duct fan to the end of my exhaust and Wwoooof!! It rockets and nothing but clear heat waves coming out som im going to run it like this while work on other stuff like plumbing and let it dry.i think i will forever have moisture in my mass because its outdoor so the fan may be forever. As for the water it gets really hot and it does convect into the tub but nothing is insolated yet and im losing heat because im so far away from it so im going to install a inline circulation pump on the cold line inbetween the rmh and the tub.my goal was to heat this tub in 2 hrs with no power but its right inbetween my outdoor bar and the shop i got power ran all over out here .ill try and get some pics of it going later .my only concern is it maybe working too well and too hot i think the reality is its working like it should be

This all  cheap smart phone and bad connection

Ok thanks .i might just have to ditch the mass tubes all together in that case they are buried under the tub in the ground which is pretty much 100% clay and never drys .ill come up with abetter transition what you were saying is exactly what i was thinking when you mentioned  it .is it just the moisture that makes the air heavier to flow ?theres alot of moisture i can see in the barrel too it makes sense .thanks

I tried posting several pics but they never want to go through

Yes Thomas .its just a horizontal pipe sealed into the bottom .what is a typical transition ?? I know the riser is fat but that Is as tight as i could get it with the 1" pipe , copper coil,and brick.my thought was to get to get some mass around it and see if it stays hotter longer .idk it was just an experiment with what i had .any advice is greatly appreciated im not really up to par on most the terms and ill be getting a book now I have seen all kinds of little homemade water heaters similar but small and metal im just trying to build a better version of the you  tube junk and if it heats the clay under the tub too that is a bonus .i can fab anything on the barrel to gain more gap around the side .i sorta got the blueprint on line for the stove that made the most sense to me but just showed the the horizontal tying to the barrel like mine .ill research some more

I thi k i need a bigger barrel haha

So im having some issues with draw i think.i was playing atound with different size pieces of wood and different kinds of wood .also the angle of the pieces when theyre in seems they do better when i lean the bottom in more .im getting a greyish cold vapor out of the stack on the end.it seems to do well at first then coals build up and it starts puffing back and burning up the feed tube untill i stir it up .sort of a disappointing amount of heat but i think its because its just not woofing like it should building up coals faster than it can burn them down..i can feel the copper get hot and work its way to the tub but just before it gets there it stops burning as well and the copper starts cooling off again away from the tub .i do have a 6" inline fan i may put on the end of the exhaust to help pull everything through just as a temp way to figure out if thats my problem before i start changing the barrel around.also at first i had maybe a 5 " gap from the top of the riser to the lid and then temp raised it to about 3" maybe ill take it back down to 5.any thoughts? I was hoping the stove would heat the water too quickly if anything like people here and other places have mentioned before abut it flashing to steam but its nowhere near getting that hot

Doing it

Thinking about using the clay pipe as the feed tube.does it matter how tall it is .16" pretty normal but does it matter if its longer ?
