The backflow three-body wave functions for a two-component system of electrons and protons were studied. Different approaches to obtain and improve trial wave functions were presented. The resulting wave functions were used in variational and diffusion Monte Carlo calculations of the electron gas and of solid and liquid metallic hydrogen. The results show that analytical representations of these functions are accurate throughout most of the phase diagram of the electron gas.
