A heat pump operation method includes: obtaining, on a per time unit basis, generated power, load power, surplus power, and an impact magnitude; and controlling operation of the heat pump to cause the heat pump to consume an amount of power for generating heat adjusted to follow the surplus power obtained on a per unit time basis. In the controlling, when the impact magnitude is greater than a predetermined first threshold value, the operation of the heat pump is controlled to permit consumption of the power supplied from an energy supplier and approximate a reverse flow of the surplus power to zero, and when the impact magnitude is less than or equal to a predetermined second threshold value, the operation of the heat pump is controlled to permit the reverse flow of the surplus power and approximate the consumption of power supplied from the energy supplier to zero.
