As I have had a heater fail and somewhat fry my tank I now run multiple smaller heaters on a separate controller to avoid that problem again. Both the controller and heater thermostat would have to fail. With smaller 100 watt heaters one broken heater shouldn't be able to increase the temperature too quick in the tank.
From what I have heard is you should replace heaters once every couple years. I primarily use 100 watt eheim jager heaters and by a bunch of them when they go on sale on Boxing day.
