I live in new construction about 2 years old. The house does not have a
root vent for the oil furnace -- the builder elected to install an
electric blower that comes on a minute before the furnace fires and
stays on for about 5 minutes after the furnaces stops.

Not to put too fine a point on it, these things are the curse of the
earth. They kill all the grass in an 8 sq ft area. I put crushed stone
under the vent and it goes rusty and black from the fumes.

But the main problem is are noisy as hell on that side of the house and
it wake us up during the night quite a few times. Had I known this
before the house was built I would have spent significant $ to either
have a roof vent installed, or a chimney even.

I include the for future googlers' benefit.

My question to the group is: Are there are quiet/quieter models of
these vents in folks' experience?

Thanks in advance,

Gary
