Do any dryers come with intake piping so that instead of using house air and
blowing it to the outside, the dryer would suck in outside air, heat it and
vent it back to the outside?

Thanks,
Richard Greene

Richard, You could probably do this, but Why??

Is the cost of heating your building air more
than the cost to heat outside air with your
dryer heat source??

Somebody has to pay to heat it somewhere...

Depending on the season this could be a valid point, if it's 100 degrees
outside and you have your A/C on cooling your house down, why would you want
to suck the cooler air from the inside as opposed to the warmer air from the
outside. Might as well just put in a big fan on the wall and throw dollar
bills into it.

Additionally, in the winter, why not find a way to put all the heat
generated by your dryer back into your home, as opposed to blowing it
outside. I know of at least one person out here in NY that runs their dryer
vent so that it exits right over a bucket of water with a screened top(the
dryer vent inserts through the screen) the water traps most of the lint, and
the heat is put into their home. The 'spring fresh' dryer sheet scent isn't
that horrible :)

Just remember, Jon, that only works with an electric dryer - you don't
want to pump that house full of CO from a gas dryer (much more
economical than an electric one where I live)!

If it's 100 degrees outside, then consider this:

A very valid reason for feeding outside air into a cloths dryer is to equalize the pressure in your
home. The blower in a dryer expells over 100 cubic feet of air per minute, leaving your house at a
"negative pressure". If your house is an air tight evergy efficient home, the dryer can back-draft
the chimney and cause your house to fill with carbon-monoxide fumes!

In some cases, this may be marginal and depend on the atmospheric and weather conditions and whether
or not a bathroom or kitchen fan is on. (first hand knowledge here )

Good point Candy, not used to seeing NG dryers so the thought didn't cross
my mind.

There's always the clothes line alternative, but not everyone uses that
even if they should, something about putting a shirt on and finding a spider
camped out in it, or worse, underwear :)

If all that moisture is getting back into your insulated wall space,
they you loose your effective insulation value.


Interesting article about non-vented attics, but here they are assuming
this works fine at 45% relative humidity at 70 degrees:

Hence, if all that water moisture is going into your walls, and
saturating your insulation, you have just defeated this purpose.

My mother bought a pre-made version of the same thing from Home Depot.
It heats the house by an appreciable amount, but the humidity is
somewhat uncomfortable. Not to mention the other problematic results
that high humidity causes, such as mildew, etc ...

They make heat exchangers which basically transfer the heat to your room
air and still allow the damp air from the dryer to go outside. I know
they have them for laundromats but I can't find a home version. It may
have to do with liability as the exchanger could become a fire hazard if
not maintained. I'll have one by next fall whether I have to build it
myself or not. My goal is to heat the garage but I may adda vent into
the house if the thing works well and safe.

Well I think this is a very important question.

Not only to prevent from a vacuum in the inner of the house but also from
prevent of the waste from energy. Might be the dryer is using more energy if
it is feeded by cold outside air. But the heat of the outgoing air should be
saved by the use of a heat exchanger coupled with the ingoing air feed for
the whole house or with a heat pump to get the most of the energy back.
