Heater in overflow?

I thought about putting my heater in my overflow, anyone have any opinions? Thanks.

 

I've heard of people doing it with supposedly no problems..

Not sure whether it would have any effect on efficiency or not?

I have a heater in each of my overflows... I think it's a great idea, especially that the water is constantly being moved past the heater, so it makes contact with a higher volume of water... seems like that would make it more efficient. Not to mention there are no animals to get to it and there is no light so it won't get covered in algae/ coralline, etc.

 

ive also got mine in the overflow with the idea that it will see constant water running around it i havent had any problems with it

 

I keep my heater there. No problems and out of sight.

 

doesnt seem like a bad idea, except the thought that, you cant heat water that fast with fire, let a lone a heater, but it should still heat it, just at a much slower rate, since the water passes over it so fast it can only heat it a little, then as the water moves a little bit of that heat escapes, but eventually you will have a nicer more even temperature......you may need additional heaters.....

 

Actually, I believe the heat transfer is more even and efficient as compared to heating a stagnate volume of water.

Initially the heater stays on longer until the tank reaches the preset temp then it will be as if it were anywhere else in your tank and only come on periodically. If its a glass heater I would be concerned about it exploding and trying to get all the shards out. Titanium would be best. JM2C

 

Its an eheim heater, I think I'm gonna put it in there. Seeing how my wet/dry is too small and I want to kinda keep it hidden.

 

how often do glass heaters explode?
