[Breaking Bad] When did Gus learn about Heisenberg

Saul introduced them but it can be assumed Gus would take note of a new producer selling high quality product on his territory. When is Heisenbergs existence first brought to his attention.

To hazard a guess, during Walt's dealings with Tuco. Gus had a prior relationship with the Salamancas, so when Tuco's crew started showing up on the scene with higher quality meth than usual, Gus knew something was up. From there he'd probably have Mike do some investigating to discover the source.
