This seems to be a yearly topic in this group, and in the past the
consensus has been that electric coil heaters and kerosene heaters are a
bad idea in shops where there is sawdust around.
These heaters have red-hot elements that certainly have the potential
for igniting flammable materials easily, even if many people post
anecdotal stories saying they have used one for years without a problem.
A better source for cheap heat are the oil-filled radiators that can be
purchased for as little as $45. I use one (1) in a 28' x 28' fully
insulated detached shop/studio and even when the temperature drops down
to near zero it will keep the entire building at 45 degrees on setting
3, where the range is 1 to 10. I estimated that it cost me about
$15/month for electricity.
The one drawback of small heaters is that while they are very good for
maintaining a given temperature, they are lousy for warming the shop up
quickly when you want to go out to work. I may install a permanent
baseboard heater on my studio side, which is separated by a wall and
door from the shop, to help with that problem.
