In the framework of a strongly interacting Electro-Weak Symmetry Breaking, both vector and scalar degrees of freedom have been studied in literature within an effective Lagrangian approach. Here I consider the case in which both a scalar, $h$, and a vector, $V$, respectively an iso-singlet and an iso-triplet under the custodial SU(2), are relevant with a mass below the cut-off $\Lambda \approx 4\pi v$. I discuss unitarity as well as precision tests constraints on the scalar-vector system. Finally I present some results on the associated scalar vector production that are peculiar of this model.
