Our Verdict
The Kismile heats your room silently. It uses oil inside metal fins to spread warmth. No fan means no noise at all.
Three heat settings give you control. Use 600W for light warmth, 900W for medium, or 1500W for full power. This helps you manage your electric bill.
You get all three key safety features. Tip-over protection, overheat shutoff, and ETL certification come standard. This makes it a safe choice for families with kids or pets.
No timer means you cannot schedule heating. No remote means you must walk to the unit to adjust it. Many competitors include both features at this price.
The heater takes about 10 minutes to warm up fully. Plan ahead before you need the heat. Ceramic and infrared heaters deliver warmth much faster.
This heater fits bedrooms and small living rooms well. At 1500W, it handles spaces up to about 150-200 square feet. Larger rooms may need a higher-output unit.
What We Like
- 1500W maximum output with three heat settings: 600W, 900W, and 1500W for flexible power control
- All three key safety features included: tip-over protection, automatic overheat shutoff, and ETL certification
- Oil-filled design runs with zero fan noise for completely silent operation
- Smooth casters and built-in cord storage make moving it between rooms fast and easy
- Adjustable thermostat cycles the heater on and off automatically to hold your chosen temperature
What Could Be Better
- No timer, so you cannot schedule automatic on or off times
- No remote control, you must walk to the unit to change any setting
- Takes about 10 minutes to reach full heat output, much slower than ceramic or infrared heaters
- No oscillation or fan to actively push warm air across the room
- At $69.99, this heater costs more than the $40 entry-level budget category threshold
