This paper describes design methods to optimize capacity of hot water supply equipments. Hot water load survey was carried out at three hotels in Tokyo. In addition, questionnaires were administered about bathing through the Internet to considerable numbers of people. Based on the results of load survey and questionnaires, optimized capacity of water heaters and hot water tanks were simulated. The required capacity based on the simulation showed a good coincidence with the result of the load survey.
