Frequently Asked Questions
Do oil‑filled heaters consume a lot of electricity?
At 1500 W, they draw roughly the same power as a standard space heater, but their thermal inertia allows the oil to retain heat longer, reducing runtime and overall energy use.
Are oil‑filled heaters safe around children and pets?
All top models include tip‑over shut‑off and overheat protection; the DREO also adds a child‑lock feature for added peace of mind.
How quickly can an oil‑filled heater warm a room?
They reach full temperature in 10‑15 minutes, then continue radiating heat gently for up to an hour after the unit cycles off.
Do I need to move the heater around for even heating?
No. The oil’s heat distribution is uniform, so a single unit placed centrally can comfortably cover most medium‑to‑large spaces.
