The invention relates to a control device () for an engine-independent heater () that heats a liquid heat transfer medium of a heat transfer medium circuit () especially for motor vehicles. Said control device () reduces a heater () capacity when an actual temperature gradient ((dT/dt) of the heat transfer medium is equal to or exceeds a temperature gradient threshold value ((dT/dt)). The control device () determines the temperature gradient threshold value ((dT/dt)) dynamically in accordance with a difference in temperature (&#x394;&#x3c6;) between a target temperature (&#x3c6;) of the heat transfer medium and an actual temperature (&#x3c6;) of the heat transfer medium. The invention further relates to a heater (), a heating system (), and a method for controlling the inventive heater ().
