DIY Boiler Build Questions
Advantageous to have the 5/16" copper pipes silver soldered in like position A or B?
Would B allow water to enter in the lower end and rise up to the higher end easier?
(They won't of course all be in the same line as shown in the drawing)
Extend them how far out from the exhaust stack? I don't see any advantage to having them as long as pictured.
Just protruding half an inch out from the stack should be enough?

Horizontal would be easier to get a good seal as round pipe and round holes.
If on a slope then round pipe and have to make holes oval

Thanks Dennis, makes total sense mate.
Any advantage to going horizontal and putting an upwards and downward bend on each one after soldering?
Hi Jim,
Any advantage to going horizontal and putting an upwards and downward bend on each one after soldering?
Yes, I think so, easier to construct and an angle down one side and up on the other will improve water flow. I usually have the pipes arrange as a helix fairly close together at the bottom of the boiler flue, the tubes going about halfway across the water space. I usually only complete a little over a circle, which if my mental arithmetic is correct for your boiler is about 5 or 6 tubes.
Take care Tony.
Bonjour Tony,
Here is our our French Manufacturer JMC makes an horozontal boiler (see at 5')
The boiler is 2 mm thick and the inside pipes 1 mm (6 x 8 mm), I let you convert in inches

Good luck with the Boiler Project Jim.
Look forward to your updates on progress.
Drilling oval holes for sloped thermic syphons isn't much of a problem if you make yourself an angled drill guide. The oval holes also provide a greater surface area for solder bonding, not that our relatively low-pressure boilers are in need of that bonus bonding.
