Disaster Barely Avoided

[TangPolice]

Bob, I'm confused. Doesn't "+1" mean "me too" or "I agree" or "one more person agrees?" So when you say "+1000," are you saying they you and 999 of your friends agree? Do you have alternate personalities that all agree? I'm just playing with you. Carry on

I'm going to go with both heaters at the same temp. There is no need for the temp to drop if one heater dies. Has anyone ever had a reefkeeper temp probe go bad? This scares me too.

Hilarious
Bob

I run heat tubes (Finnex Titanium) that are only meant to run on a controller. They are either on or off. No temp setting.

So after all of this discussion, here is what I am going to do.

I am going to put one heater tube in the sump. I am going to put one heater tube in an overflow. I will put my temp probe in the other overflow. This will give me redundancy if a heater fails. It will also give me backup in case my return pump fails, which I think is probably as likely as a heater failing.

So with this setup, here is my question.......If my return pump were to fail, would heat be able to transfer through the wall of my overflow? If it did would it also transfer through the other overflow for my temp probe to register the temp properly. I guess the best thing to do would be to put the temp probe directly into the DT but I'm not really into the idea of junking up my DT with a heat probe.

Thanks for the discourse on this guys. I think this is a very useful topic.

It is entirely possible for the transfer of heat from your overflow to your DT, but I do not see if actually making much (if any) Difference in tank temp. The best option which is kinda hard w/o spending a lot of money would be to keep your Controller powered at all times via a battery backup.

Living in the city, I'm not too worried about power failure. I'more concerned about return pump or heater failure. Power outages happen, but they usually aren't for extended periods.

I'm going to go the route of one heater in an overflow, one heater in the sump, and the temp probe in be other overflow. This will protect against pump failure or heater failure as long as both things don't happen at once.

Sounds like a good plan

While that idea is awesome, Every overflow drains lower then your tank water. Which means either your heater is going to be on with no water in your overflow, or your heater will be on heating the water in your overflow and not heating the water in your tank lol.

Only way I can see that working is if u keep a heater In your tank on a battery backup.

+1 you would just heat the water in the overflow

Run both heaters on the same outlet off the controller. Set the controller temp 2 degrees below desired temp so the power stays on. Set one heater as the main to keep desired temp. Set the second heat 1 degree low as back up. The have the controller cut the power if the temp goes above 3 degrees of desired temp. JMO

This would work for most, but I run heat tubes that aren't individually controlled. They are either on or off, and that decision is made by the controller.
