However, it does have some drawbacks. The heater requires two AAA batteries for the remote control, which adds to its upkeep. Despite its powerful heating capabilities, it might not be the best fit for rooms larger than 400 sq ft or homes with higher heating demands. Additionally, while the humidifier feature is beneficial, it might not be necessary for all users.
