Noisy heater! advice? :[

Hi all!

I bought a Whisper 5 - 15 gal heater for my 10 gal tank.

Followed the directions perfectly when I installed it. I mounted it on the back side with the suction cups. The water is nicely above the minimum water line. A day after everything is running, whenever the heater comes on ( it has a orange LED light thing ) it makes a faint chirping noise.

I can hear it from 10 feet away at my computer. It's not over-bearing and kinda faint but its there! So do all these heaters make a little noise? Do you think my fish are irritated? They don't seem to be, but I'm not sure because I'm not too good at reading fishy moods yet.

I am suspicious of a noisy heater. I have never heard any kind of sound from a heater of mine, and I have had quite a few, though not this small (25 watts, perhaps?)

I do know that many have had trouble with heaters this small, and if it was my choice, I would take it back and exchange it. Electrical devices submerged should be as safe and reliable as possible, and the noisiness gives me pause. Maybe some others who have had a small heater like this can chime in, as well.

I have a 25watt heater for my 5.5 gallon betta tank. It's cheap and crappy and the light flickers, and when it does you can hear the electricity humming sporatically through it...but a chirping sound? that doesn't sound good. I'd go get it exchanged.

My heaters give off a little click when they click on, but thats it...
