Shop heaters and condensation

[pkastagehand]

Seems like this should be its own thread rather than hijacking the "who am I" thread.

I had my mill for a while in a shop that was not regularly heated. It was a problem because the iron would be cold and the furnace generated moisture which condensed on the cold iron. Got a lot of surface rust on things if not kept well oiled/greased.

Could be a different furnace might vent more of that moisture (your mileage may vary as they say.) But for me it was a problem. I think to beat it, one would have to keep the furnace running at some nominal temperature and turn it up a bit when you want to work.

Are you using a residential type forced air furnace or more of a gas burning heater?
I know that unvented types produce significant quantities of water as part of the combustion process.
I use a couple small electric heaters in my unheated old-house basement. I put one right at my work spot to at least raise my temperature...

Unvented. This was a number of years ago. A brother had been raising some hogs and then stopped. He had this smallish unit that put out good heat but no venting. Tried just running it when in the shop but got so much moisture on cold iron that rust was a major problem.

before I moved into that little room, I was in a garage and I used a propane heater. (part 1719K2 at McMaster) didn't have any problems with condensation, athough we're out in the desert and average humidity is like 15%!
