Anna raises the temperature! Not just because of her hot looks, but mainly because this wonderful little heater is equipped with a modern PTC ceramic heating element. Anna heats discreetly and quietly with two power levels, bringing agreeable warmth. But the clever heater also stands for safety in two respects: no overheating thanks to the PTC heating element (self-regulating ceramic) and automatic shut-off thanks to the integrated tilt protection. If additional warmth is needed in certain places (e.g. under the desk or in a small space), then also check out our Anna Little. She is also "hot" enough.
