Features

Oscillation Function

Features a 100° oscillation function, which allows the heater to rotate from side to side, distributing heat across a wider area. This is particularly useful for heating larger rooms or sharing warmth with multiple people, ensuring even heat distribution.

Tip-Over Protection Function

Equipped with tip-over protection, which automatically shuts off the heater if it's accidentally knocked over. This is an important safety feature, especially for households with children or pets, preventing potential fire hazards and providing peace of mind.

Overheat Protection Function

Includes overheat protection, which automatically shuts off the heater if it detects that the internal temperature is getting too high. This prevents damage to the heater and reduces the risk of fire, providing added safety during extended use and ensuring user safety.

Adjustable Thermostat Function

Features an adjustable thermostat, allowing users to set their desired room temperature. The heater will automatically cycle on and off to maintain that temperature, helping save energy by preventing the heater from running continuously and ensuring personalized comfort.

Timer Function

Includes a timer function that allows you to set a specific duration for the heater to run before automatically turning off, ranging from 1 to 12 hours. This is useful for pre-heating a room or ensuring the heater doesn't run all night, providing convenient, hands-free operation and energy savings.

Remote Control Function

Comes with a remote control, allowing you to operate the heater from a distance. This is convenient for adjusting settings without getting up, especially useful for individuals with mobility issues, offering enhanced convenience and accessibility from anywhere in the room.
