Safe electric heaters you can run all night

I use up to 3 of These , depending on the outside temp. $19.74 at Walmart.

Hi,

Oil filled are about the safest ones to use.

I think they tell you to not run them unattended as a CYA measure.

We have used oil filled heaters 24/7 in the S&B. And I've left a ceramic heater run all night. No problems.

Just be careful of the distance from objects, and make sure the wiring can handle the 1500 watts, or whatever setting you use.

Just wondering, does the furnace have written on it somewhere, do not leave unattended?

I use a couple of those small ceramic heaters overnight, I've never checked to see if it stated that on them or not!
