just an observation , last night my ehiem 200 in my 54g tank failed . Must have been from the week long outtage, the batts i was using to keep the tanks going were not strong enough to run the heater to 80d. I had to unplug it by the 4th day and cover the tank up. So this is a pretty new heater, and i assume it got beat up from not enough juice in the batts as the tank water was 64d when it was plugged in. Its fried.
