Re: SB: Outside air, was:breathability

Norbert,, Rob, et.al--

Once more into the breach responding to the "sucker bait"...

Since I live in Texas and we are not cold enough to justify a masonry 
heater, I am much more interested in a more conventional fireplace.

In the long exchange you listed from the masonry heating association 
Website, the discussion was entirely about masonry heaters in a heating 
climate. As the excerpts said, the air requirement for a fireplace is MUCH 
higher than for the masonry heater.

It seems to me, then, that you have not at all addressed the desirability 
of outside makeup air for a fireplace.

I am quite willing to be convinced, but I have seen no studies regarding 
this, either. Could you perhaps point me to one?

I think it's always interesting to read the stuff that "everyone knows" 
based upon tests that really don't pertain to the question.

To make my own plans a bit more clear, I am looking at building in a small 
fireplace of some kind as a very occasional supplemental heat source. In 
fact, it would be used so seldom that I'm not convinced I'll even bother 
with it at all. However, if I do I am very interested in the airflow 
requirements for such fireplace, and what quantity of conditioned air is 
being used compared to the heating benefits.

So--outside of masonry heaters, is there any realistic data?
