I have borrowed a Kerosese, space heater several times. Even a 165,000
BTU one is small for my shop as it takes an hour or more to just start
to get it warm. My shop is a 3200 ft^2 hog barn with marginal
insulation and if I am working all day the woodstove works fine, but if
I am out for an hour or two in the evening, the woodstove takes too
long. I have been looking at larger heaters, like the big Master
units, 350 or 600K. Found a used one for sale. Anyone have experience
with these larger units. Any major faults? The building has a ridge
vent so there is a natural convection and fumes can get up and out.

Comments, Suggestions?

Thanks,

Bob
