Inventor: MIYAUCHI SHINJI
IPC: F24H1/00
Filed: 1991-05-02
Abstract: PURPOSE:To prevent a boiling action in a heat exchanger caused by a variation in temperature in a hot water feeding passage and a pipe passage for a bath additional boiling caused by a variation in circulation flow rate in a bath when both a bath additional boiling and a hot water feeding are simultaneously carried out in a hot water feeder having a heat exchanger of one boiler and two water passages for performing a hot water feeding and a bath additional boiling. CONSTITUTION:As a circulation flow rate caused by a circulation pump 10 in a bath additional boiling circulation passage 9a is varied, this state is detected by temperature sensing means 7 and 8 for sensing temperatures in a hot water feeding pipe passage 2 and a bath additional boiling pipe passage 3. In the case that the temperature detecting signal exceeds a predetermined temperature set value, a combustion control means 18 outputs a predetermined flow rate variable signal to a circulation flow rate variable means 17 so as to increase a circulation flow rate with a circulation pump 10 and an abnormal hot water in both pipe passages prevents an increasing of temperature.
