The compression of matter leads to exothermic reactions in the crust of accreting neutron stars. The heat deposited in the crust is transported to the surface and is detectable as a surface luminosity even during quiescence phases. Two common approximations used to model the heat sources of accreting crusts are revised. The first concerns the fully accreted crust approximation: we study a partially accreted crust made of the compressed original crust under freshly accreted material. The second concerns the instantaneous approach to the electron capture kinetics: we show that including the reaction rate of electron captures in the evaluation of deep crust heating leads to an increase in the heat release which can be as high as 20% for the shallowest shells of the outer crust. In collaboration with Prof. J. L. Zdunik, Pro. P. Haensel, Dr. M. Fortin, Mdr. N. Chamel and Dr. A. F. Fantina.
