SCHNIKEES! Bet that was honking loud.So, when I saw the thread title, I was like "Cool, I can throw my junk up there.". So, where does a Bobcat bucket place within all of this?
The bragging part was I took my gas powered lawn edger, removed the blade, and tightened up a metal cutting disc from Home Depot in it. Next think you know, I have all 4 necessary pieces cut nearly laser straight from a large flat plate of 1/4" diamond plate steel, in my own backyard on the grass, while the kids swam in the pool and the neighbors thought I just really hated the edger.
I just built a wood fired water heater for an outdoor hot tub. 55 gallon drum, 5 sticks of copper tube, some expanded metal, 2 garden hose fittings, and a $39 barrel stove kit. I really have no idea if it will work, but it should?
should have brazen the joints with either refrigeration silver or phosphor bronze. Keep it at atmospheric pressure and it should be fine. Outdoor boilers for home heating are a bit different.I thought I would bring another to the table, though it is not welding or sanding. It is not really CNC level either like some of you cool cats, but we'll see what happens.

I really have no idea if it will work, but it should? As long as water is in the pipes and not flashing to steam, the solder should not melt. Anybody that has soldered copper tubing knows it can't be done with and water standing in the pipe. Ran a few switchbacks at the top where the chimney flange flue damper valve prevents pipes from passing through. Hillbilly hot tub here we come. Could also be used to sell warm showers? It was just cheap fun really just to build it. Looks like a locomotive boiler on the inside, kind of.....or not. Garden hose male and female on the back side.

Wood fired barrel heater worked awesome this weekend! It raised a 450 gallon pallet tote full of water 5F degrees every 13 minutes. That equates to about 75,000BTU as absorbed through the 42' of copper tube within the barrel. Family of 4 stayed in it for over 2 hours as it was 20F outside.
No issues on solder melting, as expected, even for the joints directly getting licked by flames within the barrel. I used a 25gpm pump from Harbor Freight, which was way overkill on the flow, but I didn't know going into it. I will likely return that pump and buy one much smaller in flow and power to be more right sized. Thanks to WildChild467 for stoking the fire.
Yea, it was fun building the fire. I wanted to spray used oil in there to get it going. You know its a good time when the heaters are blowing flames out the stack and making rumbling noises inside! That is my style!
I still would like to see how an immersion heater would compare. Just for fun
