You hear horror stories about that stuff, but some of it may be suburban legend-type stuff. Yeah, water vapor any other place than a greenhouse is proly not a great idea. Hey, weren't you sposed to stop by me in Yonkers?? -- EA -- Ed Huntress |

Heating with propane is a no-no for many types of production environments, just due to the relatively large amounts of humidity it puts into the air. It's good for feeling warm, but bad for everything else. Like metal machinery made of non-stainless steels or iron.... Radiant electric is prolly how to do it best, from what I've heard... You can just put a bunch of little heaters, put one each right where you will need them and only turn on the one you need. |
