garage -- leaky by design? - Page 2

 


Some of the newer furnace do have a hook up for supply air as well as
exhaust air.  Have not seen that on a hw heater yet though.  Just run
a 4" pvc pipe from outside to the proximity of them.  Put a screen on
the outside.

 



My water heater has that.  It's an A.O. Smith about three years old.

I believe those are called "direct vent" just to give you a keyword

Thanks.  I knew that three years ago, but it fell out of my brain in
the
meantime.

Here is what I thought was an interesting article on the "myth" of
using outside combustion air for wood burning appliances.

While I certainly don't claim to be a "combustion scientist", it seems
to me that the same principals would apply to gas appliances.

Key question: Do you really think you can seal up your garage door to
the extent that it will be air tight?
