Does it have to be fully submerged to work

It doesn't have to be fully submerged, but it does have to be submerged up to the minimum water level line, which is right below the big black part with the dial.

No, I keep the top of mine out of the water so I can adjust the setting. I think it has to be in the water up to around the base of the top. It is a pretty good heater for my 5.5 gallon tank. Keeps a constant temperature.

No. The temperature knob is on the top and the instruction doesn't say to have it submerge in the water. I leave it covered by water according to the margin.

I have not had it completely submersed but it is sealed and other than your switch and/or splice I would think it is.

Yes. Se the temperature, ensure it is fully submerged, plug that sucker in and forget about it until it breaks...which it shouldn't.

My experience is it must remain submerged. This heater has failed at this point for me anyway. So I would suggest another brand or style. Mine didn't last very long. I am now using an adjustable version. Aquatop GH150 Aquarium Submersible Glass Heater, 150-Watt. And it works great. Lets hope it last longer.

The unit is weather resistant so it should be fine in normal rain, but it is not water-proof, so it obviously shouldn't be submerged.

It says waterproof but not really ,, I took silicon and covered the seams on mine and its better .. But I am not sure even that would work completely submerged

It can be submerged because it is waterproof but it will not work if it is submerged. The deeper has 2 halves and it creates a bubble when closed so it floats on the water

I haven't had it submerged in water but I I have been in heavy rain and it worked just fine. But nothing is waterproof. it is very hard for the water to get in. Worth every penny!!!!!

Since this outdoor, off course it takes few showers and still working. But not sure if it will survive when submerged in water ...!

I've never submerged underwater but it has been out in the rain and the equipment stayed dry.

They claim that is. I've never used it underwater. On YouTube there' are videos that show mixed results.

It is supposed to be fully submerged. I bought it for an Aquafarm and it fits perfectly.

Somewhat...I have run it in very sloppy / raining conditions and it has been fine...my guess is that you probably don't want to fully submerge it because of the motors (not good in general for a motor to be submerged...these are not fully enclosed) and the battery / controller unit.

Yes, it works great even in a small amount of water. I did put a relay in the circuit so it is not interrupting a heavy load.

In submerged mode for sure. I pump water from creek to pond via 75ft garden hose. The pump also allows to connect tubing and operate in suction mode. I have not tried that mode.

Shaun, the water draws in through those slots you see and discharges out the tube connection. It must at least be partially submerged.

There are holes on the under side, so I would have to say it really shouldn't be submerged. I don't do that to mine. But, on the other hand, it is very easy to clean, especially if you put some warm water in it after using it and let it sit for a while.
