  Heating associated with non-equilibrium nuclear reactions in accreting
neutron-star crusts is reconsidered, taking into account suppression of
neutrino losses demonstrated recently by Gupta et al. Two initial compositions
of the nuclear burning ashes, A=56 and A=106, are considered. Dependence of the
integrated crustal heating on uncertainties plaguing pycnonuclear reaction
models is studied.
  One-component plasma approximation is used, with compressible liquid-drop
model of Mackie and Baym to describe nuclei. Evolution of a crust shell is
followed from 10^8 g/cm^3 to 10^(13.6) g/cm^3
  The integrated heating in the outer crust agrees nicely with results of
self-considtent multicomponent plasma simulations of Gupta et al.; their
results fall between our curves obtained for A=56 and A=106. Total crustal heat
per one accreted nucleon ranges between 1.5 MeV to 1.9 MeV for A=106 and A=56,
respectively. The value of total crustal heat per nucleon depends weakly on the
presence of pycnonuclear reactions at densities 10^(12)-10^(13) g/cm^3.
Remarkable insensitivity of the total crustal heat on the details of the
distribution of nuclear processes in accreted crust is explained.
