PROBLEM TO BE SOLVED: To provide a bathroom heater in which water remaining in a bathroom heating means, e.g. a floor heating unit, is prevented from corroding through a simple arrangement when the bathroom heating means is not used in summer season. SOLUTION: One end of the heating tube 13 in a floor heating unit 12 is coupled with a switching valve 11 provided in an interconnecting tube, i.e., a return tube 9, and further coupled through a bypass tube 14 with the return tube 9. Water remaining in the floor heating unit 12 is replaced, little by little, through the bypass tube 14 and since remaining water is not corroded, the floor heating unit 12 can be used with no anxiety. |
