<P>PROBLEM TO BE SOLVED: To provide a liquid heating supply device (for example, heat pump hot water feed machine) which can save electricity expense by preventing wasteful boiling while preventing hot water shortage. <P>SOLUTION: The liquid heating supply device includes a liquid heating means 30 which heats liquid to be heated and turns the liquid to high-temperature liquid to be heated, a liquid storage tank 8 and a controlling means 50. The controlling means 50, in the boiling time zone, can perform such a boiling operation that the high-temperature liquid to be heated which is heated by the liquid heating means 30 is stored into the liquid storage tank 8 and, in the additional boiling time zone that is a time zone besides the boiling time zone, can perform such an additional boiling operation that the high-temperature liquid to be heated which is heated by the liquid heating means 30 is stored in the liquid storage tank 8 when the high-temperature liquid to be heated in the liquid storage tank 8 becomes a prescribed amount or less, wherein the additional boiling time zone is divided by a plurality of time zones and, every time zone, the prescribed amount is set. <P>COPYRIGHT: (C)2012,JPO&INPIT |
