The portable oil filled radiators don't have the same fire risk and work much better I find for steady state winter heating. Low is around 600W and can run a couple at that level. They are a little slower if you are trying to get heat immediately in a cold room but for regular living conditions I use them instead of paying for propane for the high efficiency forced air furnace.I was considering a "cool only" unit (lower cost & complexity),
and continuing to use resistance element type electric space heaters for the cold days here.
(Last Winter I did actually get to see frost on the roof, a couple of times, before sunrise!)
But they use 1500 watts each, and are a fire hazard.
So the "heat pump" mini split is what I'm going to try.
