Re: SB: Outside air, was:breathability

[Rick & Katy Blanchard <urbaneagle@cybermesa.com>]

Oy,

I thought the idea of sealing up a house was for tighter control of 
the infiltrating air sources to save heating/cooling energy. Part of 
this was to use an external source of air for combustion in a 
fireplace so you weren't using heated air and the energy it took to 
heat it to make fire. Aside from the adversarial tone of the 
communications and the tiny type it showed up in, it appears this is 
not the case and you are more worried about creating a negative 
pressure in the house.

Could you do a summary of the major issues and the current thinking 
on solving or handling them? If I have a reasonably sealed house, 
with less breathable walls than I thought, what do I need to be aware 
of regarding fireplaces, masonry heating, and combustion air? Is 
there a difference in requirements if I am closer to David in Tejas 
than to Rob in the Upper Tundra?

Isn't it easier to just open a window a crack and mellow out in front 
of a nice fire?

Cheers,
Rick
