I finally got our solar water heater to work, and it is not doing very
well.  The glycol comes off the roof between 126 and 145 Fahreheit.
With two small children, the abundant hot water is a Godsend.
    What are the risks if we go away for 11 days in July or August?  I
have read that a system can be damaged if it gets too hot.

It's not perfect but it's at least as understandable as a White House
speech.

 Thanks for the help. I looked at the Helidyne Gobi pages and I wonder if
this kind of collector generates lower temperatures than the Solar Rrofs
system I have. The glycol was running at 147 degrees yesterday.  126-139
is more typical.
   I bought a tarpaulin and linked it with strong thread to cover the
panel array, but the manufacturer said be careful of that plastic
melting on the very hot collectors.
    Sorry for my typo in the first message.  The system is NOW running
very well.  The only time the backup gas tank has been on in 30 days is
a week ago when my wife had a big dinner party and we ran the dishwasher
and washing machine all day long.
   I have thought of having a neighbor come in and run the hot water for
10 minutes for one day while we are gone.
