PURPOSE:To improve heat accumulating efficiency by a method wherein a heat accumulating agent, in which a heat detecting sensor is accommodated, is arranged at a position whereat the lowest temperature is obtained among the temperature distribution of the heat accumulating agent in a hot-water reserving tank and the information of the heat detecting sensor is compared with the temperature information at the outflow port of heat medium of a heating device to control the operation of a heat medium circulating pump by the value of the comparison. CONSTITUTION:The heat accumulating agent 20, accommodating the heat detecting sensor 3, is arranged at the position of the heat accumulating agent, where the lowest temperature is obtained among the distribution of the heat accumulating agents 2...2 in the hot-water reserving tank 1, while the information of the heat detecting sensor 3 is compared with the temperature information at the outflow port 5A of heat medium of the heating device 5 to control the operation of the heat medium circulating pump 6 by the value of comparison. According to this method, the pump 6 is controlled by only the temperature in the heat accumulating agents regardless of the temperature of circulating heat medium and, accordingly, the circulation of hot-water by the pump 6 may be continued until the temperature in the heat accumulating agent is increased sufficiently. |
