My home shop is squeezed into a 9 x 16 wood shed.

I can't do much in the winter because NJ is just too cold. I need to
heat it up now and then and am looking for suggestions. I tried a
small 1500 btu Pelonis electric/fan heater the other day and that was
about as effective as puppies' breath.

So, any thoughts? Space is at a premium. I'm stepping around and
over stuff as it is now.

I'd consider some sort of propane or kerosene heater provided it
wasn't a space hog or just too much of a fire or carbon monoxide
hazard.

I may be asking for the impossible.

Thanks in advance for any suggestions.
