Since it seems that heaters are one of the most common items to fail, and can fail badly, I'm wondering if it makes sense to proactively replace them every couple years.
I've got two 200W Theo heaters on my 125G reef. They are on an Apex controller, so I'm not concerned about them overheating the tank, but I am concerned about them stopping working while I'm out of town and the house is at 65 degrees, and concerned about them cracking and putting current into the tank, blowing the GFI and shutting everything down.
Both heaters are about three years old, so does it make sense to swap them out?
