Summary:PROBLEM TO BE SOLVED: To meet hot water supply demand from a user, while minimizing use of a backup boiler.SOLUTION: A cogeneration system (100) comprises a power generator (11), a hot water storage tank (21), a backup boiler (22), and a controller (60). In a case where the backup boiler (22) starts operating while hot water supply operation is forcibly executed, and in a case where a time when the backup boiler (22) starts operating is a time before a hot water supply start time, the cogeneration system suspends the hot water supply operation. In the case where the backup boiler (22) starts operating while the hot water supply operation is forcibly executed, and in a case where the time when the backup boiler (22) starts operating is a time after the hot water supply start time, the cogeneration system continues the hot water supply operation.SELECTED DRAWING: Figure 1 【課題】バックアップボイラの使用を可能な限り避けつつ、ユーザの給湯需要に応えること。【解決手段】本開示のコージェネレーションシステム(100)は、発電装置(11)、貯湯タンク(21)、バックアップボイラ(22)及び制御装置(60)を備えている。湯張り運転が強制的に実行されているときにバックアップボイラ(22)の運転が始まった場合であって、バックアップボイラ(22)の運転が始まった時間が湯張り開始時間よりも前の時間である場合、湯張り運転を中断させる。湯張り運転が強制的に実行されているときにバックアップボイラ(22)の運転が始まった場合であって、バックアップボイラ(22)の運転が始まった時間が湯張り開始時間以後の時間である場合、湯張り運転を継続させる。【選択図】図1
