摘要： PROBLEM TO BE SOLVED: To enhance energy saving performance and economy, when heating is requested, by performing heating utilizing exhaust heat only when continuous operation of a cogenerator can be ensured for a specified time or longer. SOLUTION: Upon delivery of a heating request signal, the quantity of hot water in a hot water storage tank is subtracted from the total capacity thereof thus determining the quantity of hot water storable in the hot water storage tank. An exhaust heat heating time required for attaining the storable quantity of hot water using a cogenerator 1 is then determined and compared with an exhaust heat continuous operation time sufficient for making the most use of the characteristics of the cogenerator 1. When the cogenerator 1 is operated in order to attain the storable quantity of hot water, a decision is made whether the operation is effective or not from the aspect of energy saving performance and economy. If it is effective, operation of the cogenerator 1 is allowed and exhaust heat therefrom can be utilized for heating.

摘要： PROBLEM TO BE SOLVED: To enhance energy saving performance and economy when heating is requested, by utilizing exhaust heat from a cogenerator for heating only when the operation thereof is effective and utilizing an auxiliary heating means only when the exhaust heat is deficient thereby avoiding extra storage of hot water through an auxiliary heating means. SOLUTION: Upon delivery of a heating request signal, the quantity of hot water stored in a hot water storage tank is subtracted from the total capacity thereof, thus determining the quantity of hot water storable in the hot water storage tank. An exhaust heat heating time required for attaining the storable quantity of hot water using a cogenerator 1 is then determined and compared with an exhaust heat continuous operation time sufficient for making the most use of the characteristics of the cogenerator 1. When the cogenerator 1 is operated in order to attain the storable quantity of hot water, the cogenerator 1 is started if the operation thereof is effective from the aspect of energy saving performance and economy and exhaust heat therefrom is utilized for heating. Only when the operation is not effective or the heating capacity required for heating is high, heat from an auxiliary heat source machine 6 is utilized for heating.

摘要： PROBLEM TO BE SOLVED: To enhance energy saving performance and economy by utilizing exhaust heat from a cogenerator rationally at the time of reheating. SOLUTION: Upon delivery of a reheat signal, the heating time required for boiling up the water in a bathtub with exhaust heat from a cogenerator 1 is calculated based on the temperature of hot water actually stored in the bathtub and a set boil up temperature and then it is compared with the continuous exhaust heat operation time. When an exhaust heat heating means (cogenerator 1) is operated in order to reheat hot water in the bathtub up to the set boil up temperature, a decision is made whether the operation is effective from the aspect of energy saving performance and economy. If it is effective, the exhaust heat heating means is selected and hot water in the bathtub is reheated with exhaust heat while ensuring effectiveness from the aspect of energy saving performance and economy.

摘要： PROBLEM TO BE SOLVED: To prevent run out of hot water due to variation in the quantity of hot water actually remaining in a bathtub at the time of filling the bathtub with hot water while enhancing energy saving and economy. SOLUTION: When hot water is supplied into a bathtub from a tank for storing hot water under such a state as forming a thermal stratification, the quantity of hot water actually remaining in the bathtub (actual quantity of hot water) is measured by a means 21 for measuring actual quantity of hot water, and the quantity of hot water stored in the hot water storage tank is determined by a means 25 for detecting the quantity of stored hot water. The quantity of hot water storable in the hot water storage tank is then determined based on the actual quantity of hot water and the quantity of hot water stored in the hot water storage tank, and a decision is made whether operation of an exhaust heat heating means 1 for attaining the storable quantity of hot water is effective or not from the aspect of energy saving and economy. If it is effective, signals for allowing operation of a heat/power cogenerator and a circulation pump are delivered simultaneously with hot water supply from a hot water filling means, thus obtaining hot water using exhaust heat.

摘要： PROBLEM TO BE SOLVED: To provide hot water supply equipment for a bath which makes it possible to prevent boiling even with supply of a minute amount of hot water during a reheating combustion control process. SOLUTION: In the hot water supply equipment for the bath, a control means executes a single interruption process or a combined interruption process when it detects the amount of flowing more than a set amount of interruption on the basis of the information on detection of a hot water supply amount detecting means 13 in the course of the reheating combustion control process. When it detects the flowing of hot water in an amount less than the set amount for interruption on the basis of the information on detection of the detecting means 13 in the course of the above process, the control means controls the combustion of a burner 4 so that the temperature of the hot water heated by the burner 4 be a low-temperature reheating target temperature lower than a reheating target temperature and executes a low-temperature reheating combustion control process wherein the hot water is supplied through a hot water supply passage 2 and also supplied into a bathtub 15 through a reheating passage 14.
