Talk to the folks at Jehmco who sell Ranco temperature controllers and then we'll see how "genius" your idea really is. You have a flawed understanding of this.

in which it state

For Space sensing mount the sensor where it will be unaffected by heat/cool discharge or radiated heat source.

(which sounds a lot like placing it near the heater doesn't it? )

I love Kevin's comments. Lol

Like I said. TALK to them. The Ranco controller is for industrial use (heating, cooling, refrigeration, etc). It's a little different when using it an aquarium. In the event of pump failure the heaters will not turn off. If you're away from home for a long day this could get really bad. The temps in the tank will continue to drop and the temps in the sump will keep climbing. Who knows how hot it could get. But it's easy to see why placing the probe in the sump is a good safety feature. All you need to do is monitor the temps in the tank and adjust the controller accordingly until you get the tank temps to what you like.

The heater themselves have temp sensors on them. Just set that to a sane temperature that is sufficient to heat the tank but not say melt the sump or make the sump boil before shutting off.

Not if you're using a titanium heating rod They will just burn baby burn!

Now that's different. Personally I prefer a secondary safety check.

Are the titanium heating rods better than say Eheim? or it is just about capacity?

This is actually in complete alignment in regards to my sensor placement.

With the flow of water through the sump (from left to right), the placement of my sensor in relation to my heaters is actually the most unaffected by heat/cool discharge...it's sensing water coming directly from the display.

Please take a moment to stop and think about that. My sensor's location is the farthest location from any water that has recently been heated.

Seriously, think about it.

I prefer them. Less electronics and a more simple design. It's just a titanium heating element with a plug coming out of it. Less room for things to go wrong. Aquarium glass heaters are very prone to failure and their thermostats aren't very accurate.

This is all I ask...if you don't understand ask questions. Thank you!

The amount of energy into the water is going to be the same regardless of the medium used to conduct the heat. Glass, Titanium, plastic Pex tubing...it doesn't matter...it's still going to be X watts of energy (heat) into the water.

The benefit of the Eheims is that they do have a built in thermostat that you can set to a certain temperature so that if your controller fails in the on position, your Eheims internal thermostats will shut them down preventing a cooked sump.

I am with you 100% in regards to having insurance...redundancy in your system can help prevent catastrophe.

That's why in my original statement I said when the flow slows down...See, I did thought about it before posting
