View Full Version : Submersible Heater
My submersible heater (still plugged in, still in tank, still working, but not submersed beyond the water line) has some condensation in it. Should I be worried?

Now, that's definitely not good. I would take it out and replace it.

This has happened to me all the time. I have replaced my heaters at least every 6-12 months because of the condensation inside. (One time I bought a brand new "submersible" heater and found condensation in it THE NEXT DAY.) If you continue using it when you see condensation in there, the ceramic core begins to turn brown and marks from electrical arcing can appear on the inside of the heater glass. NOT a safe situation. Many "submersible" heaters have a water line near the temp adjustment knob. Tired of buying new heaters so often for my three tanks, I began just immersing them to the water line, so only glass is below water level. Have not had problems yet.
