I heat my whole 2 story house with unvented gas wall heaters. They do very well and are extremely effecicient. I have some concern for the use of them in my shop, however, because of the open flame.

In my experience with these heaters, I find that the blue flame type generates a lot of water, but the ones with the ceramic elements that generate infrared do not.
