<DIV><FONT face=Arial size=2>The information about a single tank with undercover
vs. two tanks under the beams is especially helpful to me. I used a heater
bar under the keybed of my S&S A (1914) when I had no AC in the
summer and the keys got sluggish. Since rebuilding I've always had
AC, so I don't know if the new key-bushing job solved the problem or
not. The keys on this B need attention--without going into the
whole story, I'll make them right and then see what happens.</FONT></DIV>

<DIV><FONT face=Arial size=2>This is a piano faculty member's home
instrument. I believe she'd be more interested in what will make
the piano perform at its best in regards to the Edward's String Cover. I
have a feeling she'll go for it to protect her investment--especially since
AC isn't used in the summer. Wanna bet?! Aw, just kidding...

<DIV>Hi Barbara,</DIV>
<DIV>I've found some pretty interesting installations, too. If
installers would just consult with Dampp Chaser before getting creative,
things would work much more smoothly.</DIV>
<DIV><BR class=khtml-block-placeholder></DIV>
<DIV>Dampp-Chaser was also sending out a large fold out of piano schematics
and recommendations for a while. You might contact them. I believe
it was free. I haven't seen the ones on the web site, but they are
probably the same. Part of their extensive research involves the most
effective installation, so they are the ultimate authority of what you should
do.</DIV>
<DIV><BR class=khtml-block-placeholder></DIV>
<DIV>The only issue I have a problem with with the two tank system with
undercover is the difficulty involved in servicing it. It is so much of
an issue, in fact, that it is too much easier to say, "oh, we'll do it next
time." But if you change to a one tank system, I believe you will have
to repurchase it. I don't believe a two tank system can be converted --
at least Dampp Chaser recommends you don't mess with the plumbing on a two
tank system. Certainly any remaining warranty would be voided.</DIV>
<DIV><BR class=khtml-block-placeholder></DIV>
<DIV>Here in the Southeast, we have more trouble with high humidity than
low. That really isn't the issue because the system continually cycles
day in day out year around to average 42% (or whatever humidistat you
choose). I installed a two tank system with undercover in a new B in a
church 4 or 5 years ago now. It's an above the beams installation and I
added a third dehumidifier rod (24" 25W) installed along one of the long
beams. It also has a double padded instrument cover by Jill, and they
keep it on the piano unless it is being played. That piano doesn't
move. It is as stable as granite.</DIV>
<DIV><BR class=khtml-block-placeholder></DIV>
<DIV>The systems on my Bs here at the school predate the availability of the
two tank systems and I installed them below the beams - at the time, that was
the recommendation if you weren't using undercovers. I really need to
add undercovers, but I just haven't had time to redo the installations to
above the beam, so I haven't been able to get to that. But to compare
the effectiveness of the single tank system with no undercover to the two tank
system with undercover is to compare night and day.</DIV>
<DIV><BR class=khtml-block-placeholder></DIV>
<DIV>I don't like the heater bar under the keybed. Too much risk of
drying out the pinblock, and I have long legs. It burns. I think
DC recommends against it, too. Since it is in their home, a
Steinway B will be a showpiece as much as a musical instrument. I think
the string cover might go over like a lead brick in that situation.
Recommend they keep the piano closed as much as possible when not in use
or being displayed.</DIV>
<DIV><BR class=khtml-block-placeholder></DIV>
<DIV>I would use what is there and simply reinstall it per Dampp-Chaser's
recommendation and add the undercover.</DIV><BR><BR>
