The "Senior Member" designation under my name doesn't mean I know a lot, it just means I talk a lot.I've been a DIYer since I was 12 (thanks, Dad!). I have read several books on various home improvement topics. I do not have any current code books I can refer to. I was an apprentice plumber for two years.
your problem was a combonation of a circulator with no timer/ thermostat (plugged in running 24/7) and unreamed tubing and most likely exessive oil based flux your lucky the leak was right at the heater.. i strongly suggest having a plumber or sparky install a timer or stat on the pump..
those solder joints in your photos were very poorly done you can see the section you unsweated the solder only partialy took
I agree about the cause of the leaking. I don't know about excessive oil based flux. Your original post was what made me disassemble the whole system and replace all the copper. It is very obvious from the picture that the copper was not reamed and the erosion was immediately after the ridge where the turbulence from the water flow would be the greatest. This system was installed by a licensed plumber. He also installed other systems in houses in my subdivision. I have to assume their system has or will soon leak, also.
I have installed a timer on the pump but I think I would rather have a thermostat that controlled the pump. Any ideas on a thermostat would be appreciated. Thanks!
Just an opinion from a plumber, this erosion from turbulence from unreamed pipe is hogwash. It would not happen that fast.
I am not a plumber but I can look at the evidence and make an assumption based on what I see. If you have thoughts as to what would have caused the erosion on the the inside of the tubing other than water erosion, please post them here so we all can see them. I think that the ph of my water is close to 7 so I don't think it was caused by acidity of the water or something like that. The water was 130 - 140 degrees and was flowing 24/7/365. Bad copper? Thin walls?
Something caused the tubing to erode through in less than 4 years. Your thoughts would be appreciated.

You could be dealing with a process called electrolysis. This is like a cancer that will continue to spread. rather than emptying your wallet on repairs. consider replacing the entire line. Use a poly ethylene product.
