A back-up boiler system for a solar thermal power plant () for transferring solar energy into electricity, said back-up boiler system comprising a combustion chamber () and a convection section () in fluid connection with said combustion chamber (), wherein in the convection section () at least a first heat exchanger () is provided for heating a molten salts mixture of the solar thermal power plant and a second heat exchanger () for pre-heating boiler feed water of the solar thermal power plant, wherein the back-up boiler system () is configured to allow selection between only providing heat to the first heat exchanger (), only providing heat to the second heat exchanger () and providing heat to both heat exchangers (), preferably dependent on availability of solar radiation and/or dependent on demand of power generation. The invention also relates to a solar thermal power plant () for transferring solar energy into electricity and a method for operating a solar thermal power plant.
