Just writing to vent my frustration, and possibly warn others.
i've had my 55 gal SW
tank up for a little over 2 years... the whole time, i have run 2 150 watt won pro heat ii heaters. a little over 1 year after starting, both of the heaters decided to fail. slowly, the temperature display drifted higher and higher, well over 100 degrees. thankfully, they fail in the off position.
i replaced these with 2 new 150 watt won pro heat ii heaters. yeah, you would have thought i learned my lesson. anyway, fast forward to this week (about 1 year after the last set was replaced). currently, one of the heater displays is starting to drift up again. again, it has failed off, so i dont have to worry about it turning on. im pretty much waiting for the other one to fail.
i saw one other post on this topic from about a year ago. is this a common theme for these heaters? they seem to just fail after a year of operation. as i've stated, i've personnally had 3 of my 4 heaters fail within the last 2+ years.
im gonna try some visi-therm stealth heaters and see how they work out. i have a visi-therm deluxe in my water change bucket, and it has yet to fail. granted, i only run it when i make water, but it seems to be a more reliable heater.
