It's been over a month now and the 6.3 Ohm resistor is still working.

Today it's warmer out (38F) so the power is down to about 725 watts.
(That's 90% of the 800w PV array's rating).

And I think that little 2,474 BTUh is helping, because the water temperature
is staying up around it's 140F setpoint on most days..
(The oil burner's timer turns it on for 30 minutes at 6AM each morning).

Late last evening, we wanted to take two showers. So, I went down to the
boiler to give it a 10 minute burn cycle and found it wouldn't come on..
The burner controller was on standby.. Since the water temp was just a tad under 140F..
