The blocks heat up and, when the electricity is automatically turned off, the heat is slowly released into the home from the blocks over a long time.

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.

What is the weight of 10 inches thermal blocks?

The weight of 10-inch thermal blocks can vary based on the material and density used in their construction. For example, concrete thermal blocks typically weigh around 25 to 30 pounds per block. Therefore, if you're considering a standard 10-inch block, you can estimate the total weight by multiplying the weight of one block by the number of blocks you have. Always check the manufacturer's specifications for precise weights.

Are concrete blocks cheaper then a concrete slab?

That's sort of a strange question. A concrete slab is a horizontal surface -- it's meant to be a surface you stand on or build things on. Concrete blocks are usually used for vertical surfaces -- walls. I believe that poured concrete walls are more expensive than concrete block walls. You wouldn't use concrete blocks as a substitute for a concrete slab.
