According to examples, an apparatus may include a processor and a nontransitory computer readable medium storing machine readable instructions that when executed by the processor may cause the processor to receive a requested power demand from a first heating component and a second heating component, compare the requested power demand to a first threshold, and select a sequencing and stacking group of a plurality of sequencing and stacking groups for the first heating component and the second heating component corresponding to a result of the requested power demand being compared to the first threshold. The instructions may also cause the processor to control application of power to the first heating component and the second heating component according to the selected sequencing and stacking group.
