However, its high wattage may lead to increased energy consumption, potentially impacting energy efficiency negatively. Additionally, this model may be on the pricier side compared to traditional space heaters.

Despite these drawbacks, the Dyson Hot+Cool™ AM09 is a strong contender for those seeking a multi-functional device with advanced features for heating and cooling large rooms.

The heater includes useful extras such as a remote control, 12-hour timer, child lock, and memory function, which add convenience and enhance user experience. However, its heating coverage is limited to 200 sq.ft., which might not be sufficient for very large rooms. This heater is ideal for individuals seeking an efficient, safe, and quiet heating solution for medium-sized rooms or specific areas within larger spaces.
