The Box IP21 fan heater also provides pleasant warmth in the bathroom or guest toilet, as it is splash-proof thanks to the IP21 protection class. With a powerful 2,000 W, two heating levels and three switching levels (ventilation, warm air, warm air), the Box IP21 fan heater spreads the desired comfortable temperature. This can be continuously adjusted using the thermostat. For additional convenience, it is equipped with a 2-hour timer and 70° oscillation. This means that the air is optimally distributed throughout the room. The modern design with covered controls fits harmoniously into any office, living room or bathroom environment. In addition to protecting against overheating, the tip-over protection also ensures safety. If the device is accidentally tipped over, it switches off automatically. The robust plastic housing is equipped with a practical carrying handle, so that the Box IP21 fan heater can deliver heat wherever it is needed.

Specifications

Same summary

The Unold Box IP21 fan heater is designed to quickly heat up small or medium-sized rooms, such as bedrooms, bathrooms or a home corner. Thanks to two power levels, you can adjust the heat to your current needs, and the built-in overheating protection provides additional safety, especially during occasional or prolonged use. It is recommended primarily for situations where central heating is not enough or when you need a portable heating solution for the weekend or during transitional temperatures. Due to the power of up to 2000 W, it is slightly less suitable as the main source of heat in very large or constantly cold rooms.
