A heat accumulation system has a plurality of chemical heat accumulation units arranged in parallel and each incorporating reaction vessels containing, respectively, a chemical heat accumulating material such as zeolite and a reaction medium such as water. Any surplus heat which could not be used in the regeneration of the chemical heat accumulation material in one system is utilized for evaporation of a reaction medium in the other unit. Disclosed also is a method of operating this system.
