In the books
In the Song of Ice and Fire novels, a chattering 16-year-old servant assists Daenerys with her bath. She does not give a warning but Daenerys does think about the temperature;

"The water was scalding hot, but Daenerys did not flinch or cry out. She liked the heat. It made her feel clean. Besides, her brother had often told her that it was never too hot for a Targaryen. "Ours is the house of the dragon," he would say. "The fire is in our blood.""
