Control manner of solar thermal warm water system and solar thermal warm water system

摘要

P To solve a problem that as the solar HEAT water heating system having a conventional auxiliary HEAT source device sometimes heats water stored in a hot water storage tank by the auxiliary HEAT source device for anti-freezing and sterilization, the hot water heated by the auxiliary HEAT source device is mixed into the hot water storage tank and which adds a HEAT amount heated by the auxiliary HEAT source device to a measurement value of a collected HEAT amount measuring device. PSOLUTION: A solar HEAT water heating system 1 includes a forcible circulation type solar HEAT water heater 2, the auxiliary HEAT source device 4 for heating the hot water delivered from the forcible circulation type solar HEAT water heater 2, the collected HEAT amount measuring device 3 for measuring the collected HEAT amount of the forcible circulation type solar HEAT water heater 2, and a prohibition means 5 for prohibiting measurement of the collected HEAT amount measuring device 3 during delivery of hot water if the hot water heated by the auxiliary HEAT source device 4 flows into the hot water storage tank 21 of the forcible circulation type solar HEAT water heater 2.
