Anywhere where there is water flow is a good place for a heater, as this will move the water away from the heater to prevent 'hot-spots'.

There's no real "correct" place to put them. As for orientation, as long as the heater can be placed horizontally (some direct you not to), the it doesn't matter which way you mount it.

While I was setting up my tank, I had two (glass) thermometers. one at each end of my tank, just to double check I was getting a consistent temperature through out the tank.

I keep mine horizontal also usually about an inch or so above the sand.

In the 30 gallon, I keep It vertically in the back on the opposite side of the thermometer.
The 20 gallon it kind in between the middle of vertical and horizontal in the back of my tank.
The 6.6 Its vertical, and once again opposite side of temp gauge.

If you have a bubbler, it's good to put it under the heater to help circulate the heated water. I put my heater horizontally and low enough so that I don't have to turn it off for water changes.

That's a good idea! I once forgot to plug it back in after a water change...

Good morning,

In my 265g, all 3 heaters are vertical due to the fact that the cords are not long enough for me to have them horizontally. They are about 2 inches away from the bottom of the tank. Right, middle, and left hand side of the tank. (submersible heaters)

The heaters in my other tanks are placed horizontally about 2 inches from the bottom, in the center of the tanks.

I keep my thermometer in my filters. With a constant circulation in the filters, this gives me a more accurate temperature reading. I also like to use at least 2 thermometers per tank.

Ken

Yesterday I realized that I have an adjustable heater. Nice! I keep it in back horizontally, aprox 2" from substrate. But today I realized there is a water line. Oh no! This has been submersed for over 2 months! Can I leave it alone? I'm afraid of breaking it by now exposing to air. I also found out the 2nd heater is broken when using for QT.

Mine are generally on an angle right below my filter intake. This is especially effective in my 55gal with the canister filter. I have my thermometer on the bottom right side of the tank, on the complete opposite side as the heater (which is a 200W)...and my thermometer reads 81F all the time.

I think the waterline is the lowest the water can be, not the highest. Hope that's right.

Correct. Most submersible heaters need to be in a certain amount of water to function properly. The water level is the minimum depth of water.

And not trying to go to far off topic - ironically, the very water that the heater is heating, is also used to keep the heater cool

Otherwise, the heater would heat the glass (of the heater) too much, dry it out, and crack it

I have a corner tank, running two filters on the back I keep the heater mid level horizontally between the two filters.

I have a heater on the back wall of each tank, with a thermometer on the front wall, opposite end. In two of my tanks the heater is right beside and/or under the filter outflow, but not by design. Makes sense though. I think I'll move the heater in the newest tank to the other side, by the filter, too.

I have a Rena smart heater that is vertical, It works like a in-line heater because it is the intake for the filter. It heats both the tank normally and the intake water. I also keep the thermometer near the spray bar.

I like to keep mine at the back of the tank over a airstone/bubbler of some sort so it gets dispersed somewhat

I think it should have a MAX Water Line and a MIN Water Line, (mine does anyway) hope this helps.

Submersible heaters only have a minimum water line......there is no max because they can be completely submerged.

Non submersible heaters have both max and min water lines.
