I am getting to the point of deciding what type of heat to install
in a new workshop. The shop is 30'x54' with 10' walls and will be
insulated to R-20 in the walls and R-38 in the ceiling. I have
natural gas available and am trying to decide between using one or
two of the ventless "blue flame" gas units or a single ceiling
mounted vented gas furnace. The ventless units would be less
expensive and have a few other advantages, but I have heard that
because they do not vent combustion air outside of the building
they
can lead to potential moisture problems. Is this an issues to be
concerned about? The shop will be used for woodworking and
fossil/mineral preparation so a moisture problem would not be good.

Thanks for any recommendations or advice any one has.

May or may not effect a shop, but our kitchen has a "ductless" range
hood and I'll never do that again...
IMO, an activated charcoal filter doesn't replace venting heat and
exhaust outside..

Depends on where and when you are. In a New England winter blowing
all your heat out through the range hood isn't all that comfortable or
cheap. On the other hand, in the summer after the house has heated to
an uncomfortable temperature, sucking in some nice cool night air can
be just the thing.
