The invention discloses a heating adjusting method and device and belongs to the technical field of thermal system management. The method comprises the following steps that the average indoor temperature of a community is calculated, wherein the average indoor temperature of the community is the average value of the real-time indoor temperatures of all households in the community; whether the average indoor temperature is in a standard temperature range or not is judged; and when the average indoor temperature is not in the standard temperature range, at least one of the water pump flow and the water temperature which are provided for the community is adjusted. When the current average indoor temperature of the community is abnormal, by adjusting the heating water pump flow and water temperature, the temperature of the community is restored to the standard value, the response speed of the heating adjusting method and device is high, reliability is high, the user experience is improved, and energy is saved.
