Abstract
Disclosed is a hot water supply system provided with a tank which holds a high-temperature liquid, and a heating means for generating the high-temperature liquid which is stored in the aforementioned tank. In the lower portion of the aforementioned tank is provided a water-heating heat exchanger which heats the water to be supplied to a hot water terminal by means of the liquid present in the lower portion of the aforementioned tank. Further, a hot water supply circuit is provided which conducts water to the aforementioned hot water supply terminal. The aforementioned hot water supply circuit splits into a water-heating path passing through the aforementioned water-heating heat exchanger, and a bypass path bypassing the aforementioned water-heating heat exchanger, and is provided with a hot water supply circuit control mechanism which controls the circulation state of the water in the aforementioned water-heating path and the aforementioned bypass path.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
