I disconnected the 800w array from the old oil burner boiler,
and hooked it up to the GE water heater 230 input.

It's been cloudy, but I did see some peaks up to 750 watts! (2559 BTU)
Mostly, when the sun was out, it was weak. 400 to 500 watt range.
Right now it's putting in about 15 watts!

But, when the sun was out earlier, it worked pretty well.
10:25AM 39.6C (103.28F)
11:10AM 47C (116.6F)
That's a 13.22 F gain in less than an hour. Not too shabby..

We've been using a little hot water this afternoon, and the temperature
at the test point has been staying between 47C & 50C.

I wanted to try this experiment, because of the low heat loss of this GE tank.
So, even without pre-heating, I might be able to cut the amount of A7 run time.

I'm also thinking that I should buy one of those Blankets for the tank.
The metal skin of the GE tank is slightly warmer than my drill press.
