On all my jager heaters they have a water line, they recommend you don't submerge past there.

I'd take that advice. Being shocked by your heater is not a fun time. I was setting up a QT with a cheaper glass heater and reached in to plug place a powerhead and got a good shocking! Now I stick with the Stealth heaters and use 2 smaller heaters should the controller fail I don't have a boil over!

They are fully submersible, you dont want the water level to drop below the line on them.

NEVER get a heater that is not fully submersible, that is old school. The line is where the heater needs to be at least in the water so it doesnt get cracked, which would equal the shock of your life.

Jagers can be fully immersed, I've had mine running that way forever. The line is for "never go below here".

The old Jagers were not fully submersible. The new ones made my Eheim are fully submersible.

:furious: VERY TRUE! :furious:

I had gotten this older heater in a purchase on craigs list and had kept around thinking I'd have a use for it. I've got two small plastic stealth heaters in my DT and now have one I purchased for my DT too. Not ever taking the chance again!!!!!!!!!!:thumbdown

Because they are a very reliable and failproof (when used properly) heater. I have one that has been in use for over 7 years. ;)

The way I understand it is the old ones are. They're just not sold that way. Has something to do with not having a "UL" listing as a submersible. I have three that have been submerged for 4 yrs now with 0 issues.

Just bought a new one of these (already have two others). At the store the clerk explained that the water line was there to comply with CSA (and the US version - SA?) until they could get the rating for fully submersible. I guess they are considered fully submersible elsewhere in the world, but weren't approved for that in North America till now. They have apparently doubled up the thickness of the cord on the new ones to comply and now they are rated for fully submersible according to the front of the box.

Cheers,

Correct. All of the jager heaters are submersible. When eheim bought the company, they had to go through a UL re-cert. Eheim support will tell you this. The heater design has not changed, but until eheim gets the new UL listing as submersible, they must sell the heaters with a water line. I emailed eheim support and asked. I have a fw cichlid tank with one of the newer eheim jager water line heaters fully submerged.

Guess I type too slow on a Sunday morning as your answer posted first.
