Fact of the matter, both oil filled heaters and that other heater produce the same amount of btu's per watt.

Both work just the same as far as heat output is considered.

I use oil filled heaters like you Flamethrower, work great in my opinion.

They MAY lower the room humidity, but it's not as bad as other heating types.

I will however say I was always intrigued by those infrared heaters, but after looking at the btu's per watt, I'll stick to my oil filled.
