Electronic Heater Failure Database

[ingchr1]

I thought it would be interesting to have a thread documenting failures of heaters with electronic thermostats. If you have had a failure please reply to the thread with the following information. For unknown information just annotate as such.

Manufacturer:
Model:
Watts:
Failure Mode: On/Off/Catastrophic
Mode of Control: Internal/External (Internal if the heater was being controlled by its own thermostat at the time of the failure, External if it was being controlled by an independent controller at the time of failure)
Control Band: +/- 0.0F (only if external control, otherwise N/A)
Heater Cycles per Hour: (only if external control, just average #, otherwise N/A)
Time in Use:
Date Manufactured:
Other pertinent information: (e.g. heater ran dry, power surge, etc.)

I’m not sure what kind of conclusions, if any, will be able to be drawn from the data but who knows. At the very least we will have data on in-service failures.

Great idea

I have had 2 in the past and both were junk. One was 4 degrees off on the digital read out. Both failed in less than a year. Sadly I do not remember the brands. One a lower priced one the other a higher priced name brand.

My 50W submersible Hagen is dead on. It's been plugged in for 14 months with zero problems.
There's been a few comments from hobbyists routinely replacing their heaters to prevent problems like the contacts welding together.
Maybe I should consider a new one.

I have had them all fail. All-Glass/Aqueon, Won, Ehiem, VisiTherm, etc. Never had a Ehiem fail on. I have always controlled them with a Ranco or Medusa.
