What do you think about an oil burner with just a chimney outlet then build a water jacket chimney. I'm thinking like 1" diameter of water around the chimney with a flow pump to keep it from over heating. That would solve your weld access problems to get it water tight. It would not be a large reservoir of hot water, only an external heating element for something like a hot tub. you could also make your water jacket any height you wanted then, but also you'd end up with a lot of weight high up which could be a safety issue. You could incorporate both to harvest even more heat off the exhaust while also being configurable as you could run the heater without the chimney jacket. I'm also thinking if you had just a heater with a water jacket chimney, you could configure a different chimney to power something like a sauna for dry heat.
Thanks for your comment, I really appreciate it when people give me food for thought! I did think up a solution for testing the inner weld on the water reservoir! The first task would be completing that inner weld around the flue and adding a test bung to the combustion tank. That way you can pressure test it before cutting the door and moving on with the build. I like your idea for various chimney options and smaller waster jacket, coincidentally you will see a departure from the reservoir water heater design in my next version. Not exactly how you described but it eliminates the storage tank and any welds that could potentially leak. I also expect to increase efficiency considerably!
The combustion tank is a 20lb propane tank, the top is a 30lb tank. The second video (pt2) in this build series shows details on the burner construction. Waste Oil Burning Water Heater - WOBWH Build Pt2 ruclips.net/video/XdFCLfdyegc/видео.html
Great video! Thanks for sharing.
Thanks, glad you enjoyed it!

I can't wait to follow revision 2! @@rad1876
What type of tank are you using and the size? Can you post pictures of the burner? Thanks
The combustion tank is a 20lb propane tank, the top is a 30lb tank.
