<p><P>PROBLEM TO BE SOLVED: To provide a liquid heater of low energy loss which starts in a short time at start time of a supply water supplying action even in the case that the supply water supplying action is conducted under a circumstance where temperature of liquid in a storage means is low. <P>SOLUTION: In the liquid heater 1, a main body part 2, a combustion part 3 and a muffler 4 as well as structuring members of a supply water system X, a heating system Y and a bath system Z to be described hereinafter are provided in a casing W. The supply water system X is structured with a heat exchanger 30 for supply water as a center. The heat exchanger 30 for the supply water is provided apart from a storage part 6 below it and capable of heating the supply water by heat exchange with thermal medium supplied from the storage part 6 by actuating a pump 32 for heating the supply water. The liquid heater 1 delays start of the pump 32 for heating the supply water until the thermal medium in the storage part 6 reaches a predetermined temperature C. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
