I moved into a studio apartment in a commercial building turned residential. It has this kind of heater—
—which I believe is an electric air heater. It's loud as hell.
Everything I'm reading says oil-filled radiators are far more cost-efficient for larger spaces, despite being slower to the heat the room (which I don't mind).
So I had 2 questions, actually.
Are there any caveats to running 1 or 2 high-capacity oil-filled radiators? Like safety concerns, especially considering the apartment is equipped with a sprinkler system as also shown in the photo. (Is a building fire + oil-filled radiators + cold water potentially extra, extra bad?)
I'm just curious, why would cost-conscious businesses want to use the kinds of heaters pictured, on top of all the noise? Why did commercial buildings opt for them instead of oil-based tech in the first place? I don't imagine quick warmth and comfort for industrial employees would have been the reason.
