JS1987 Posted February 19, 2012 Report Share Posted February 19, 2012 Hi novice question here I am setting up my tropical tank and would like to know can i fully submerse my heater in the tank at the moment its about half way down the tank on the left the cord is running up and out from the tank to the power outlet its an Aquaone brand with the purple adjusting knob at the top. Thanks Quote Link to comment Share on other sites More sharing options...
GrahamC Posted February 19, 2012 Report Share Posted February 19, 2012 Heaters are built to withstand full submersion but it is said to be preferable to leave the top out of the water. Quote Link to comment Share on other sites More sharing options...
Sophia Posted February 19, 2012 Report Share Posted February 19, 2012 I've seen them all the way to the bottom of the tank but I still leave the top poking out just in case. Not sure it would really help if something did go wrong but you never know :thup: Quote Link to comment Share on other sites More sharing options...
Hamstar99 Posted February 19, 2012 Report Share Posted February 19, 2012 they are fully submersible. Should say that on the packaging. Quote Link to comment Share on other sites More sharing options...
Ira Posted February 19, 2012 Report Share Posted February 19, 2012 I put mine at least halfway down. That way they don't become exposed when I do water changes. It's just annoying having to remember to unplug them and then plug them in. I had a tank that the cord didn't reach far enough for that. So many times I'd have it draining out the door and check the tank to find it full of steam and the heater sizzling away. Or the other extreme I've left the heater unplugged for a week or two and only noticed it when I stuck my hand in the tank and it was about 17°C.

Sheepsnana Posted February 19, 2012 Report Share Posted February 19, 2012 I have mine fully submersed, I was informed that the water acts as a coolant for the top half. Some people put them on a slant to reduce the heat rising into the control circuits, but i reckon that the little amount of heat that is reduced from the slant isn't significant. :dunno: Just my 2c.

alanmin4304 Posted February 22, 2012 Report Share Posted February 22, 2012 Many heater/thermostats are not rated for complete submersion and most seem to end up with moisture in them after a while---can't be good for the electrics. Quote Link to comment Share on other sites More sharing options...
smidey Posted February 22, 2012 Report Share Posted February 22, 2012 i would first check that it states fully submersible than you can put it where you like. I have mine either vertical or horizontal on the bottom to hide it as much as possible. I wouldn't recommend your to be put vertical, i would put it on a 45 deg angle.

Cricketman Posted February 22, 2012 Report Share Posted February 22, 2012 always had them fully submersed and on a slant, means that the bi-metallic strip is measuring average tank temp rather than the warmed water rising of the element giving a false reading. note: not a problem if you have decent flow past the heater to drive the "pocket" of warmth away from itself. horses for courses.

smidey Posted February 22, 2012 Report Share Posted February 22, 2012 it comes down to the quality of the heater to, i have jagers vertical and horizontal and they both keep the tank at the temp they are set at. Quote Link to comment Share on other sites More sharing options...
