Pro and Con of multiple heaters in one tank

'tis true, but I think what is important to realize is that if any ONE heater fails, it is not going to do any damage (or at least "not as much"). So, the risk of a failure is more, but the risk of potential damage is mitigated. So goes the theory, anyways.

<font size="2" face="Verdana, Helvetica, sans-serif">I agree. If you have 3 heaters in your tank and one of them fails, the other 2 will simply work overtime to keep the temp correct. Unless of course one of them gets stuck ON. Then that's why we'd need this safety system regardless of how many heaters you have.

Multiple heaters:
Great safety net if one fails and shuts down
Useless if one fails and stays on
