Abstract: A vehicular heater includes a heat medium circuit connected to a heater core that heats vent air via heat exchange with a heat medium. The heat medium circuit includes a first flow path connected to the heater core through a power unit, and a second flow path arranged in parallel with the first flow path and connected to the heater core through a heat source different from the power unit. A controller adjusts a first flow rate of the heat medium in the first flow path to be larger than a second flow rate of the heat medium in the second flow path when the power unit is operating.
