Probably already know the answer to this, but thought I'd check here just in
case.
About 7 or 8 years ago I got a Visitherm 100W tank heater and was running it
without incident for a few years. Sometime after, this tank was switched to
holding coldwater species and instead of removing the heater from the tank,
I just left it unplugged.
Now, I'm not sure if there's an optical illusion or something, and although
I have fairly good eyesight, it looks to me like there is water in there at
the bottom. I did test the heater by switching it on across an RCD and it
behaved as normal. I didn't see the water touch the heating element though,
and I wasn't going to be handling it whilst in these circumstances.
Can there really be water in there, I thought these things were 100%
waterproof, even after all this time?
