Summary: | To provide a technology capable of improving energy efficiency in a hot water filling operation without damaging convenience of a user, in a hot water system including a heat pump.SOLUTION: A hot water system includes a tank, a heat pump, circulation means for circulating water between the tank and the heat pump, a combustion device, a hot water filling instruction device for instructing the start of hot water filling in a bathtub; a bathing detection device for detecting bathing; and a controller. The hot water system can execute a hot water filling operation in which water in the tank is supplied to the bathtub while heating the water in the tank by the heat pump. The controller is constituted so as to estimate bathing start time of that day based on the bathing start time of each day during a first predetermined period in the past. The controller sets a flow rate of water supplied to the bathtub in the hot water filling operation of that day based on the start time of the hot water filling operation of that day and the estimated bathing start time of that day.SELECTED DRAWING: Figure 5
【課題】ヒートポンプを備える給湯システムにおいて、ユーザの利便性を損なうことなく、湯はり運転におけるエネルギー効率を向上することが可能な技術を提供する。【解決手段】本明細書が開示する給湯システムは、タンクと、ヒートポンプと、タンクとヒートポンプの間で水を循環させる循環手段と、燃焼装置と、浴槽への湯はりの開始を指示する湯はり指示装置と、入浴を検知する入浴検知装置と、コントローラを備えている。給湯システムは、タンクの水をヒートポンプで加熱しながら、タンクの水を浴槽へ供給する湯はり運転を実行可能である。コントローラは、過去の第1所定期間における各日の入浴開始時刻に基づいて、当日の入浴開始時刻を推定するように構成されている。コントローラは、当日の湯はり運転の開始時刻と、推定される当日の入浴開始時刻に基づいて、当日の湯はり運転において浴槽へ供給する水の流量を設定する。【選択図】図5 |
