Can this heater be fully submerged?

Yes it actually needs to be fully submerged and is designed to work that way. If you are going to remove it for cleaning etc. you need to unplug it first. It should never be plugged in out of the water.

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

I have this heater fully submerged in a 5.5gal betta tank and I have had no problems with it. When you get the heater and actually see it you can tell it is sealed very well.

Due to the nature of a thermostat operated heater, you cant really over-do it. I have a 12gal with this heater and it works great, yes it has to be completely submerged, but that is not a problem for me. I plan to upgrade to a larger tank, hence the overkill.... so if you might have a bigger tank someday, just get this one!

We did not submerge the LED light in water and actually have it sit on a piece of glass between the tank and the tank hood. Looking at the LED light fixture I'm not so sure I'd trust it to be submerged in water as there is some weakness in its assembly that would allow water to penetrate the fixture. We have had ours continuous day to day operation for over a year now without issue.

It is fully submersible. I use it in a 2 gallon tank for a betta, shrimp, and dwarf frogs. Also extremely accurate.I just took a look at the reviews. First of all, this heater is for a small tank, maybe max of 2 gallons. The room it is in stays about 68 degrees, and this heater maintains the water temp at 78 degrees. Secondly, it has a minimum water line, but the entire unit can be submerged. One reviewer said that he didn't know what the factory preset was, I put it, started it up and then adjusted it up to 78 degrees. I think the preset was probably 72. This was the smallest heater I could find that was controlled with a thermostat. It is fully submersible. I use it in a 2 gallon tank for a betta, shrimp, and dwarf frogs.

It has to be submerged fully. Trust me, I found out the hard way. I ended up having to buy a military style jerry can with a big opening to get this pump in.

I don't see why not, as long as it is treated in the same manner as a hair dryer - kept away from a water-filled sink or bathtub. I just love this heater. It is so quiet that I can't tell it is running. I work from home full time, and it keep it aimed at my feet as an alternative to raising the thermostat. Why heat the whole house all day when I am in only one room?

The advertised answer is yes, but I don't need to in my tank so I've never actually done it. There is an extension that comes with the cleaner to add about 4 - 6 additional inches to its reach. I don't see anything that would preclude it from working submerged. It seems to be well sealed. I hope that's some help.

No, you are better having it fully submerged. The bubbles will help circulate air into the water.

Yes. I was initially concerned (water & electricity don't mix...) however it was DESIGNED to be submerged. I placed it touching the bottom and when cold my Beta would swim and hang out under it!

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.

It is not designed to be mounted inside the furnace so I don't think it is submersible. You may want to check directlly with the company though.

Yes, just don't plug in the unit until it is completely submerged. If the heating unit is heated out of water, it will burn out.

I too have a shallow bird bath. I try to keep it submerged but winter evaporation often exposes the top (heater has 3/4" depth). I would not let bird bath run totally out of water because the thermostat will probably keep it running constantly trying to heat the air. Unplug if you are going to be gone for days. Mine has kept running fine for 3 years.

There is a double wall on this heater. I was thinking like you where this is concerned. I had an older heater of this type that i could leave a pot of water on. The top of this one is only warm.

The instructions warn you not to let it run dry. I can only assume that it will damage the heater if you do.

It does not have to be submerged in order to work, if the intake is supplied with water. Like at the low end of a closed loop system. But it won't pull water up from a reservoir.

It will be completely submerged is fine in my 5 gallon will go down about halfway in your tank
