[RE-wrenches] Shucco Thermal Collectors

[Bill Loesch]

David, Mike, Carl, et al,

Just a heads up regarding the Corrugated Stainless Steel Tubing (CSST)
cutting technique. If you opt not to get the dedicated tubing cutter; not my
recommendation but an option, at
least get the profile rollers and use a sharp (new) dedicated wheel in your
own tubing
cutter to cut the very thin CSST. What ever amount of feed you give the
cutter with copper it's way too much for CSST. The profile rollers will keep
the very sharp cutter in the same track and make a clean break if you feed
slowly. If you don't, you will collapse the tube or get a non clean break
with a burr and get to start all over
again. If you start over enough times the new cuts will make the length a
bit
too short to do the job.

Remember to bond the CSST as per manu. instructions. If this CSST behaves
anything light the gas CSST, without bonding, it may develop a pinhole leak
when subjected to nearby
lightning and arcing occurs between the CSST and another ready ground. At
least some manufacturers address the arcing issue with a better jacket.

There are benefits and disadvantages to almost everything.

David,

I have the Schuco SlimV and HE I-80 system installed here at home in
Cincinnati.  I am happy with the system, and today we had a good solar
day 955 W/sq m at 1:0 PM, and the collectors were still running at 122
degrees at 4:00 PM.  We have the Premium V collectors installed at
CInci State College and last week these ran the 80 gal HE 1 from 60
degrees at 8:00 AM to 132 degrees by 1:00 PM.  We're runinng an
Apricus, Schuco, and AET system side by side there and the Schuco
generally comes out on top.

I agree with Michael, the documentation is good but read and follow it
carefully.  I've had some trouble getting the tank adapters (BSP to
NPT) to seal so careful attention here as well.  The line sets are
nice but I prefer the corrugated SS sets available from Caleffi for
flexibility.

Schuco tech support, customer support , sales support, packaging and
shipping is excellent.  If the single wall HX is an issue then
consider opting for another tank  (the also provide the Rheem Rudd
Solar Aide for those cases where you need electric backup).
