See the Chaffoteaux boiler heaters, with a piece of copper pipe around a plate:

I think it's not difficult to DIY it with some solder !!
Copper is not wasted on these exchangers !!
and therefore we risk overheating if the water circulates badly !!
These boilers have not improved in 35 years, there was more copper on the heating body !!!
In addition, a copper pipe does not leak since it does not exceed 100 ° C as explained by gaston, since no vapor spurts out !!
I can hardly understand how he can run away, even after 35 years, unless it is a real filth !!!!

calydra 23 ff & heating body leak '...
good evening, this type of pot is the worst of the chaffoteaux range, too bad, it breaks the image of the brand, because the other models in terms of quality price are more or less valid .. bye this is the first boiler I have have had she already had 5 years and so I can not say if the more it leaks, change it is more on it is the same as that of nectra, centora, hyxia, calydra, elexia, g23, nexia and certainly of other chaffoteau model after 1994, ref: 1010017 around 150th does not put hot water more than 1/4 you are looking for
My pif tells me that it leaks elsewhere than on the copper tube of the heating body which never undergoes the direct gas flame !!
The joints of the heating body or elsewhere !!
Beware, it is easy to err in estimating the cause, even with a professional plumber !!
there is also :

You have to think like a detective by not missing any clue to find the real culprit and not an innocent one !!
Looking at the pictures the plates are rusty (not the water tubes) above, and I have the impression that the water is flowing from above and rusting below ???
I have the impression that it is rusted well above, follow the rust going up to the top where the leak must be well above the heating body !!
To be seen with great care, with this principle: the water falls, flows downwards and causes rust on its path, while the leak is well above the heating body ??????????
I have the impression that the tube with water is not damaged, only the plate welded on it, because of the hot water flowing over it coming from much higher ??????? !!
