Gary, just as a matter of interest can you remember what gauge of copper you used ? I realise that isn't anything to do with the problem you are having but I'd like to compare what you used with the materials I have
Hi Florian -Thank you so much for this.I am knocked out by how much attention and expertise you have brought to bear on my boiler leak issue, and by your advice which I shall follow to the letter as you have clearly understood the situation completely.Regarding my sequence of assembly, I don't know how you knew it but you are quite right. As a complete beginner, I was terrified above all of having big gaps between the end caps and the barrel, so I erred too much in the other direction, i.e. with caps that were so tight that I had to turn them down to get them in. I thought about making the caps/tubes structure first, but decided it could be a real struggle to get it into the barrel as a complete assembly, hence my decision. And, of course, I was unaware of the heat loss/conductivity issue that you describe. Something for me to do differently next time...I also realise now that the bronze screws that I put in were unnecessary, especially given the tightness of the caps. They were just an expression of my insecurity A friend has just pointed out your Cochran boiler thread to me - it looks amazing, and I look forward to reading it.Thanks again, and have a great weekend.gary
