I have a 25W TopFin heater in my 10g and lately I have noticed the little orange light never shuts off unless its unplugged. Sure enough, I have seen the temp rise to around 84, at whihc point I unplug it. However after 36 hours or so it will drop down to 76 and then I plug it back in.
I have had the heater for around 18 months or so, in your experience how long do they normally last? All I have in there is a betta, cory and snail so they aren't that sensitive and I have been home a lot lately to keep an eye on it. But with any luck I'll be back to work soon and want it to be more reliable.
One of my heaters must be going on 10 years now...the others are at least 5...
If it's made properly and well, it can last a very long time...just watch the rubber on the cords and stuff...once that wears, it's probably time to toss it...

Only thing I have noticed is some white crust build up but I assumed that was due to my very hard water leaving some type of deposits, as I find it on the rim of my tank as well sometimes.
No matter how long anyone's heater works, yours is junk waiting to kill all your fish.
Get a new one. I like the Via Aqua Ti submersible heater with remote senor and temp setting dial. If you ever upgrade to a bigger tank, this can be used with a slightly higher wattage and you redundancy.

I agree 100% with Cermet. You have time bomb in your tank waiting to cook your fish. Your fish would be better off with no heater until you can get a new one than with that one.
