We investigate out-of-the equilibrium properties of the electron liquid in a two-dimensional disordered superconductor subject to the electric bias and temperature gradient. We calculate kinetic coefficients and Nyquist noise, and find that they are characterized by distinct effective temperatures: $T_e$, characterizing single-particle excitations, $T_{\mathrm{Cp}}$, describing the Cooper pairs, and $T_{\mathrm{eh}}$, corresponding to electron-hole or dipole excitations. Varying the ratio between the electric $j$ and thermal $j_{\mathrm{th}}$ currents and boundary conditions one can heat different kinds of excitations tuning their corresponding temperatures. We propose the experiment to determine these effective temperatures.
