Our Verdict
This heater does three jobs in one unit. It warms the air, adds moisture, and creates a 3D flame effect. Most heaters only do one of these things.
The motion sensor stands out from the competition. It detects when you leave the room and shuts the heater off automatically. You save electricity without touching a button.
At $115.70, you pay more than a standard heater. But you get a humidifier and flame display built in. That combination is hard to find at any price.
The missing timer is a real drawback. Competitors at this price commonly include one to two hour scheduling. If you want to wake up to a warm room, this heater cannot do that on its own.
What We Like
- Reaches full 1500W output in just 2 seconds for instant warmth
- Motion sensor automatically shuts the heater off when you leave the room, cutting energy waste
- Built-in humidifier prevents dry air while heating, a rare combo in one unit
- 90° oscillation spreads warm air across the entire room instead of one direction
- Complete safety package includes tip-over shutoff, overheat protection, and V0 flame-retardant housing
What Could Be Better
- No timer to schedule heating sessions, a feature common on competitors at this price
- No WiFi or app control for remote management from your phone
- At $115.70, it costs two to three times more than basic 1500W tower heaters with similar wattage
- Estimated heating coverage of around 150 sq ft falls well below the 300+ sq ft many competitors deliver at this price point
- Indoor-only rating means it cannot be used in garages, workshops, or covered patios where heating is also needed

Frequently Asked Questions
Common questions about 3-in-1 Space Heater with Humidifier, Space Heaters for Indoor Use with Motion Sensor/3D Flame Effect, 2s Fast Safe Heating 1500W Portable Heater for Office/Bedroom/Home/Room/Garage/Electric Heater
How large of a room can this heater warm?
The heater runs at 1500W, which is enough for rooms up to about 150 square feet. It works well in bedrooms, home offices, and small to medium rooms. It is not strong enough for large open living areas.
Can the humidifier and heater run at the same time?
Yes. The product uses separate water tanks for the humidifier and the heater. The two systems stay isolated from each other for safety. You can run both at the same time for warm, moist air.
Is this heater safe to use overnight?
It includes tip-over shutoff, overheat protection, and V0 flame-retardant materials. The motion sensor also powers it down if no movement is detected. These features make it safer for overnight bedroom use than many basic heaters.
How loud is this heater during normal operation?
The heater runs at 35 decibels. That is quieter than a soft whisper and well below the noise level of a normal conversation. Most people can sleep or work next to it without distraction.
Can I adjust the temperature without getting up?
Yes. A remote control is included. You can set the temperature anywhere between 41°F and 95°F, switch between modes, and turn the unit on or off from across the room.
