So this morning my wife sends me a text early (late for her, I
think she
was up at like 4AM) and says the hot water was minimal when she
took a
shower. First thought was, well it helped wake you up, but that is
beside the point.
So I ponder this a minute and remembered having a warm shower
yesterday
evening (warmer than ambient, which is quite warm at this time) so
figured the water heater was pretty much OK, yesterday anyway.
Then I
recalled she had done like 4 loads of laundry, so figured that
drained
down the tank (80gal electric) but it should have recovered
overnight.
So then I remember there is a control box the electric company
has in
there that supposedly they could control the thing. Now the PO
of the
house told me as near as he could tell it never did anything,
but he got
a break on the electric bill so let them put it in. I put in a new
water heater 3 yr ago, and as near as I can tell the control box
never
did anything either, but I hooked the WH into it anyway when I
replaced
it (and I thought about bypassing it, but did not as it was
easier just
to wire into it).
So I go look at the WH in the closet, and shonuff the light on
it is
blinking. It has some sort of "smart" controller with an LED
blinky,
and the code said "Failed Initialization" or something. I am
not sure
how a WH initializes, other than just turning on and off, but
there you
go. So I push the reset button and the light goes steady, I
hear the
coils start to heat water, bueno. I guess it initialized happily.
So then I go look at it a while later and the green light is
completely
off, and the controller box LED display says "P" whereas before
I think
it said "O" and of course there is nothing on the box to
indicate what P
and O mean. I figure P means off and O means on, whatever sense
that
makes. It has "Bypass" and "Vacation" buttons, the "Vacay"
button turns
the controller off (or some other symbol lighted up, I forget)
and back
on, the "Bypass" button doesn't do anything at that point. Anyway,
after awhile it comes back on again, with an "O" showing and
there was
hot water for evening shower. I guess it recovered OK during
the day
when it was running.
I am figuring since it is fairly warm these last few days the
electric
company is actually doing some controlling and the controller
confused
the WH "smart" controller to where it was having fits. I am
wondering
if that external power on/off is going to bugger my WH or WH
controller
at some point.
Technology marches forward. We are in the woods with not a lot of
direct sunlight at any given time during the day, or I would
seriously
consider augmenting the thing with a solar panel water heater of
some sort.
