Heater probe placement

[FishPureLuck]

Where does everyone put their heater probes for controlling their heaters?

I put my probes in the sump in the section before the heaters, so I am getting a more accurate representation of the tanks temp (without having the probes in the tank itself).

In proximity of the heaters. The reason is if circulation stops.....say a heater in the sump and the probe in the DT and the return pump fails......the probe will be calling for heat, and the sump will be cooking hot.

I never even thought about that. I just didn’t want the probes visible in my display.

That's probably what I'll do and have done in the past. And that also goes along with what redfishbluefish mentioned about a failed return pump. Both of my heaters are right next to my return pumps in my AIO, I guess the chamber right after the filter sock would be the perfect spot along with the rest of the probes.

I go with the overflow box or near the drains in the sump. Since this is the temp of the actual tank without being in the actual tank.

For most systems anywhere with decent flow is fine really.

In the first section of the sump, right under the overflow and emergency pipes.
My reasons were that this is as close to the tank as you can get without being visible and it looked neat when plumbing everything in! I appreciate that any temperature drop through the sump could be calculated but It works for me.

It's a good point about protecting against return pump failure. However, I know the cycle time for my heaters and I have set my Inkbird will notify me if the they have been on for too long essentially warning of pump failure.
