Submersible Heater - Whats with the Line?

My jager heater, and also my old heater (came with all-glass kit) have a "do not pass" line on them. keeping the dial above water level .. Ive read a few posts and see a few pics where the recommended placement is horizontal and down at the bottom of the tank. I understand the logic but isn't that dangerous?

Well,

I'll take a stab at it at least:

I'll assume you do not pass the line for the sheer fact that other than teh glass tubing is concerned, anytime that heater of any type has a dial, there is a pivot point that cannot be 100% sealed from water.

I imagine over time that trace minerals in teh water, let alone the water itself would seep into ANY crack or seam in a heater. I would then imagine that once the elements made contact with the water the results would be catastrophic...like those movies where they drop a hair dryer or a toaster in a bathtub....instant death to your fish, not to mention blown fuses in your house.

Just my speculation though

Without seeing your heater, I"ll take a stab at answering too

Are you sure it's a submersible heater? Submersible heaters usually say "minimum water line" , meaning that they must be submerged at least up to that line.

But if it says something like "do not pass", you probably have a non-submersible heater. Do you still have the box or anything that came with it? It probably says something like "do not submerse" above that line. So you must keep the water level no higher than that line, or else you might have disasterous consequenses like jaysono mentioned. 8O

If you have a submersible heater, that means you can put the whole heater, dial, and cord into the water. That's the type of heater you can position it horizontally at the bottom of the tank if you want. But it doesn't seem like you have that type of heater.

I have submersible heaters, and I have the whole heater, dial, and about 3 or 4 inches of cord in the water. Since you can't submerse your heater below that water line, if the dial sticking out of the water is a problem with closing your hood, you could get a submersible heater. I have the new Visitherm Stealth heaters.

Actually, it's a good idea to have a spare heater on hand if one breaks. (If I had listened to my own advice, I would not have had to make a mad dash to the hatchery one Sunday! Now I have like 3 spare heaters, lol.) You could use the Visitherm and keep the non-submersible for a spare. Here's a link on the Stealth heater. They are on sale now at DrsFosterSmith:

ok , im an idiot . but just to make sure.. confirm if this is right..

this is exaclty what it looks like:

the line says : "Do not immerse beyond water level"
this is the line ---------------water level--------------

so, if my brain is working right.. that means that the water level should be at the line or above it! .. not below.. meaning I can infact place it horizontally at the bottom.. i think, right?

Don't talk about yourself that way, lol!

So, it does seem that you cannot put your heater in the water below that line -- you have a non-submersible heater.

OK...hmmm...it is under the "submersible" category and it says completely waterproof. Does the picture look like what they sent you? Is it possible that they sent you another one by mistake? I've never had this brand -- I will look around the internet and see if I can find another description.

Me too. So don't feel bad. I just ordered a new heater from Big-Als. A visitherm. As much as I like the ebo-jagers, I need something submersible. I was rather perturbed when I got mine and saw it gave the a water line warning. Although, I have had it underwater before I read that line, and it is fine so far.... *crosses fingers*

Next time, go with a visi-therm. I love mine.
