Thermal evolution of neutron stars with variable internal heaters distributed over stellar crust is discussed with special interest to the effects of crustal supefluidity. Superfluidity can significantly shorten and intensify the thermal surface emission from a star in response to the internal heater's outburst. This may be useful for interpretation of observed outbursts of transiently accreting neutron stars in low-mass X-ray binaries as well as of long bursts of magnetars.
