I doubt the leak is be a nail.
Expansion / contraction would have pulled the repair long ago.
I would be getting prepared to have to find it and do a proper repair when you put in a new boiler regardless.
I would be looking at why your system can't do its job properly. You've a big boiler so either the controls/configuration isn't right or you live in a barn.
I would then do a system review before buying anything. Look to the modern way of heating controls (full rad control with wifi/App controls) and work backwards from what you want to get a system you will like.
Most new heating contols (Wiser, etc) seem to have opentherm or other compensation technology built in, so it's plug and play really.
Once you specify your job properly, you may find opentherm isn't needed.
The 4 bed detached house built in 1990 has dot and dab dry lined walls. The ground floor is in microbore while upstairs is in conventional piping. I note your comment about doing a proper repair to the pipe but this would be extremely hard to find so I would rather not rip the house apart unless the leak came back.
You mention why my system can't do its job properly but it works fine for me so I think it is. The gas engineer fitted a 42Kw boiler as I said I wanted a good hot water flow. The house has 11 radiators including 5 doubles plus two towel rails . It was only years later that I figured out that the cold tap was running at 12 L/m. Seems the boiler installer didn't bother checking so over specified the boiler. I think he had only just come out of training school.
