Popis:	In this paper we aim at characterizing the gauge balls in the Heisenberg group $\mathbb{H}^n$ as the only domains where suitable overdetermined problems of Serrin type can be solved. We discuss a one parameter family of overdetermined problems where both the source functions and the Neumann-like data are non-constant and they are related to the geometry of the underlying setting. The uniqueness results are established in the class of domains in $\mathbb{H}^n$ having partial symmetries of cylindrical type for any $n\geq 1$, and they are sharper in the lowest dimensional cases of $\mathbb{H}^1$ and $\mathbb{H}^2$ where we can respectively treat domains with $S^1$ and $S^1\times S^1$ invariances.
