What about chemicals/metals/minerals getting into the water from
parts of the hot water system?

From copper?

Perhaps the heat makes difference or perhaps the types of metal used
in boilers and their pipe joints makes a difference?

After all these years I'd have thought the evidence would be there if it
happened.

Do micro-leaks occur from the heating circuit (which passes through
the boiler's heat exchanger) into the hot water used for washing?

Ah. Perhaps a good idea to avoid a combi, then?
