They are cheap and I feel like they're safe when running on low setting.
cheap
That's why I just bought 2 of the "Amazon Basics Portable Radiator Heater with 7 Wavy Fins, Manual Control" $54@.

They are extremely basic, NO temperature controls to go wrong. But I've plug in thermostats from the past which have proven to work VERY reliably so I plan on using those to control when the radiators get power ( assuming power is on).
My BIL has an "empty" house just north of me and (previously unknown to me) he's been heating with oil filled radiators to prevent freezing for years.
I also plan on investing in some big round thermometers so I can check the temp, and room with my Wyze cameras. They also look out for intruders (mice).
That setup, heaters, thermostats, cameras, wifi plus our standard practice of turning water off for long term absence.
So for the purpose of this thread the question:
any recommendations for such Portable Electric Radiator Heater, Oil Filled in the 1500 watt size?
has been overtaken by price.
I appreciate the info supplied here, just wish my BIL had spoken up sooner.
And I'm amazed at no mention of pallets or rounded drain plugs.
