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.

We have a ventless gas fireplace in our dining room. it came with the house.
When it gets really nippy out we light it.
It very quickly causes the (vinyl, dual pane) windows to fog in the dining
room, kitchen and living room. It also creates an unplesant smell. Not the
smell of gas I think the smell is from the dust that collects on the fake
logs. It causes my eyes to burn sometimes. This summer we reworked the
fireplace hearth and surround when we put the travertine in the dining room
and I cleaned the fake logs. I hope it helps.

My point is, it's still spooky to think that the oxygen is being depleted
and the carbon monoxide has nowhere to go. We never leave it on for long
usually just to stand next to and thaw out for a little while. I surely
would not go to sleep with it burning.

Someday, I hope to get the darn thing vented somehow. I miss our old
fireplace. It was wood burning and had a great insert in it. it would burn
all night long and keep the house pretty warm.
I'd suggest a good vented heater. You might consider a heat/ac unit so you
are covered all year around.
