Abstract
A method of controlling a heating system includes: obtaining, from a power supply source, information specifying an output modulation period during which power consumption by a heat pump unit is to be reduced; and controlling, based on the information obtained in the obtaining, an amount of heat generated by the heat pump unit. In the controlling, the heat pump unit is caused to generate a first amount of heat per unit time in a period other than the output modulation period, and generate a second amount of heat per unit time during the output modulation period, the second amount of heat being less than the first amount of heat.
