Why storage heaters contain concrete blocks though the specific heat capacity of concrete's lower than water?

Because water is a fluid so heat can transfer by convection to the surface of the radiator can be 'radiated' into the room very quickly. Concrete is an aerated solid so can't do this, and is a very poor conductor, so loses its heat a lot more slowly. The concrete bricks are also aerated, and air is an even poorer conductor than concrete.
