Moisture in heater

[TRD_Power]

I picked up a used 50W heater today for my 10g breeder tank and I noticed there is a bit of moisture in it... Is this a problem? I don't feel like having my house burn down from an electrical fire :/ I have only bought metal heaters so sorry for my ignorance.

Thanks!

I would like to know also, I have a heater like this, and its been working okay, and never electrocuted me; however I still planned to to replace it.

The moisture is usually an indicator that the heater has a tiny leak. Your house will not burn down however you may get a tingle when working on your tank (especially so in salt water). I've had this when I submerged a non submersible heater, particularly Ebo Jaegr heaters. Only submerge them to the water line on the heater and the problem will go away.

Cool, thanks!

Yep, it means the seal is broken and water is getting in.

I would be wary of the water inside it heating up/boiling and exploding. Just a thought. no experience with that happening though
