Abstract: . . .  estimate that, as compared to the case of conventional systems, model customers (i.e., those using hot water for bath rooms and living space, e.g., for under floor heaters) who install gas engine cogeneration systems and are eligible for this agreement will be able to save about 27,000 yen per year in the sumtotal of gas and power tariffs (in the case of the Tokyo district).  . . .
