Frequently Asked Questions
Do these heaters actually warm up large rooms?
The 1500W power combined with advanced heat dispersion tech (like M-shaped fins and dual heating tubes) pushes heat faster and wider than standard models.
Customers note it heats spaces evenly, but room size, insulation, and ceiling height play a role.
For bigger areas, let it run 20-30 minutes to reach full effect.
Are oil-filled radiators safe around kids or pets?
Cool-touch exteriors stay 30% cooler than traditional heaters.
Built-in tip-over protection cuts power instantly if knocked over.
Flame-resistant materials and automatic shutoffs add layers of safety—no exposed heating elements.
Can using an electric heater save money on heating bills?
ECO mode adjusts output based on room temperature, avoiding energy waste.
Lower settings (600W/900W) maintain warmth without maxing out power.
One customer cut their central heating use by 40% during daytime hours.
How quiet is “quiet mode” really?
No fans mean zero humming or buzzing—just heat radiating naturally.
Some notice a faint clicking when the thermostat adjusts, but it’s quieter than a whisper.
Perfect for bedrooms or home offices where noise distracts.
Why does my new heater have a weird smell at first?
Manufacturing residues on heating elements burn off during initial uses.
Open a window and run it on high for 1-2 hours to clear the odor.
If the smell persists past 3 uses, contact support—it shouldn’t last.
