BATHROOM HEATING SYSTEM

摘要

PROBLEM TO BE SOLVED: To inform ready for bathing accurately by informing it when extra heating to a predetermined temperature and heating under specified conditions are completed. SOLUTION: An open circuit performing extra heating operation and heating operation simultaneously while passing through a bathtub 15 opens a three-way valve 14 on the bathtub 15 side and the return circulation circuit 10 side and closes the three- way valve 14 on the bypath circuit 13 side. A circulation pump 9 circulates water in the bathtub 15 through a return circulation circuit 10 in the direction passing through a heat exchanger 2 and a supply circulation circuit 11. Water in the bathtub 15 is heated by a burner 3 and returned back to the bathtub 15 after radiating heat partially through a radiator 16. A person taking a bath sets an extra heating temperature and a heating temperature by means of a remote controller 20 and turns on an operation start switch. When the temperature in the bathtub 15 reaches the level set by means of the remote controller 20, switching is made to closed circuit operation and only the heating operation is sustained. When a hot air thermistor 21 reaches a predetermined heating temperature set by means of the remote controller 20, heating operation is stopped and ready for bathing is informed by sounding a buzzer through the remote controller 20.
