....the amount of air turnover...by volume...in most of our homes is pretty staggering- most ppl don't believe the mathLightning wrote:So according to this table, one pound of Anthracite Coal needs 11.7 pounds of air for combustion..
My basement is roughly 15ft x 15ft x 7ft cube = 1575 cubic feet..
SO if this is all correct then my furnace uses one full volume of the basement in combustion air every 5 and half hours..
And that doesn't count what the baro is sucking up the chimney which I would think is grossly more than combustion.

When you're heating your house most of the mass you're heating is the house itself - walls, floors, etc., - not the air in it. It doesn't take a lot of BTU's to heat just the air, so some amount of turnover of air is not a big problem. If anything, turnover of air is needed to maintain the quality of the air in the house.

but some ppl just cant believe how much "air " the average home turnsover in a day....even when you show them !
EXAMPLE: in Lightnings scenario above... the typical electric household CLOTHES DRYER would evacuate his basement in about 11 minutes....as compared to his stove ( 5 1/2 hrs)
