-> Normally, the water is so hot that the gas heater doesn't come on.
-> It's more of a backup source.
My electric backup heater didn't come on at ALL today until well after
sundown.  But I'd like to "store" more hot water and I haven't come up
with a suitable tank for the purpose.  Right now the 'collector' is the
storage tank, and a lot of my 'storage' is blowing away since it hasn't
been properly glazed yet.  (Been busy with associated projects.)
 -> The water actually gets hotter if we use a lot of it!
I was surprised to find this seemed to be so here as well this afternoon
when we were testing the plumbing around the new tub.  (Which is the
CAUSE of all this...)
