I've used and recommended the Heartland for years. IMHO, it's the
only outside dryer fixture with even a hope of preventing backdrafts
- and it does that reliably. <br>
<br>
It's also provides the easiest access for clean-out of the duct of
any system I've seen or tried.<br>
<br>
Most clients love it, once they get past the "mushroom" appearance.
<br>
<br>
I have only heard of one complaint. A friend, not a client, said
that when he tried one, his dryer took longer to work. I haven't
seen his system and he didn't provide more detail, but this is
completely at odds with other feedback.<br>
<br>
I suspect that his duct run may be the real problem - too many
elbows and/or a long flexible duct run - but I have not had an
opportunity to check further. I believe he mentioned that the cup
never rose fully; also odd. However, it was a chance comment on
meeting in the street, so details and my memory are sketchy.<br>
<br>
If you install one, I recommend making sure the connecting duct is -
or converting your current exhaust run to - straight, smooth pipe;
sealed and with the minimum length and fewest turns possible. Where
possible, use two 45's in place of a 90 degree elbow. Make sure the
pipe seals to the dryer discharge and the outside vent. If a short,
straight run is not practical, change the duct to 6" (most
installations I see are usually 4"), with a reducer at the dryer if
necessary. The Heartland is set up to accommodate a 6" duct for a
reason.<br>
<br>
If the run is long, or convoluted, consider adding a clean-out
access at a point that will let you sweep the full length. (Lint
build-up could be another of my friend's problems, and a fire hazard
to boot.)<br>
<br>
I hope this is useful,<br>

<div>I've seen some positive reviews about the Heartland Dryer

if anyone on this list has experience with it. See: <a

<div>I've also read the marketing info on the Tamarack

href="http://www.tamtech.com">www.tamtech.com</a>) Cape
Backdraft Damper, which seems like a good idea and well designed
product. See: <a moz-do-not-send="true"

<div>Seiho Intl. makes high quality dryer vents with backdraft
dampers, but I have no idea how effective the backdraft
protection is. I would much rather have an ugly vent that
really prevented backdrafts than a beautiful one that only works
ok.</div>
<div><br>
</div>
<div>Any ideas or suggestions welcome.</div>
