Abstract

The present invention provides a heat pump type heat source unit that reduces the possibility of rainwater adhering to the control board even if rainwater enters the enclosure. [Solution] The hot water heater 1 includes a fan case 50. The fan case 50 is positioned in front of the air heat exchanger 24. The fan case 50 includes a front wall 51 and a mounting plate 29. The front wall 51 has an opening 511. The mounting plate 29 is fixed from the front to the periphery of the opening 511 of the front wall 51. The mounting plate 29 has an opening 291. A ventilation guide 60 is positioned between the fan case 50 and the front cover. The ventilation guide 60 has a ventilation path portion 61. A control board 100 is provided to the right of the ventilation guide 60. The ventilation path portion 61 of the ventilation guide 60 is positioned to overlap in the front-rear direction with respect to the opening 291 provided in the mounting plate 29 and the ventilation opening portion provided in the front cover.
