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.

An evaluation device includes a set temperature evaluation portion, an ecological driving evaluation portion, and a notification portion. The set temperature evaluation portion determines a set temperature evaluation value based on a set temperature that is a target temperature. The ecological driving evaluation portion is configured to determine an ecological driving evaluation value based on at least the set temperature evaluation value. The notification portion is configured to notify the occupant of the ecological driving evaluation value. The level of power saving rises with change of the set temperature evaluation value or the ecological driving evaluation value. When the set temperature is changed, and the change of the set temperature causes increase of the level of power saving without decrease in power consumption of the vehicular air conditioner, the set temperature evaluation portion changes the set temperature evaluation value in the one of positive and negative directions.
