Abstract
A heat exchanger includes: a case which has a first side wall that stands upright in a vertical height direction and to which a heating medium is supplied inside; and heat transfer tubes for heating hot water housed in the case. Two end portions of the heat transfer tubes in a longitudinal direction are joined to the first side wall via brazing portions, and the heat transfer tubes are supported by the first side wall. The heat exchanger further includes heat transfer tube support portions provided on the first side wall for supporting portions of the heat transfer tubes near the first side wall to prevent the portions of the heat transfer tubes near the first side wall from descending below a first predetermined height.
