We explore the contribution of electrons accelerated in the jets of high-redshift microquasars to heating and ionizing the intergalactic medium through Monte Carlo simulations of the propagation and energy deposition of these electrons. Microquasars contribute significantly to heating the intergalactic medium and are effective ionizers only near the galaxies. Their effect on heating is of the same order of magnitude as that of cosmic rays from supernovae.
