Frequently Asked Questions
Are these heaters safe to run overnight?
Both Dreo models and the Lasko heater have ETL-certified safety features like tip-over protection and overheat shutoff.
The Dreo heaters use flame-retardant materials and auto power-off after 24 hours.
Key takeaway: They’re designed for safe, unattended use, but always plug directly into a wall outlet—no extension cords.
Will these things jack up my electricity bill?
Depends on your settings.
The ECO modes on Dreo heaters adjust wattage (900W-1500W) based on room temperature to save energy.
Lasko’s adjustable thermostat prevents constant high-power usage.
For deeper cost breakdowns, check out how ceramic heaters stack up against other types.
Do they actually stay quiet?
Dreo’s bedroom-focused model runs at 32dB—quieter than a whisper.
Even their louder 40dB option beats most traditional heaters.
Lasko’s tower design keeps noise minimal, but some users note slight hums on high settings.
Can they handle a large living room?
The 1500W Dreo heats up to 200 sq.ft., while their upgraded 25” model covers 270 sq.ft.
Wide 70° oscillation pushes heat into corners.
For very open spaces, pair with ceiling fans to circulate warmth faster.
How long do these heaters last?
Dreo’s oscillation mechanism is tested for 750,000 cycles—roughly 10+ years of regular use.
Both brands use durable PTC ceramic elements that don’t degrade like older coil heaters.
Keep vents clean, and avoid humid areas to maximize lifespan.
