I have been running without heaters for months now, the pump I have is heating the water to 84, at first I thought my heaters broke as I had them set to 80. I unplugged them both and left it like that for a few days and the water never dropped. I have since plugged them back in but they never kick on.

Any one else have a tank that runs without heaters?
 
220 powered by a mag drive 50
 
how many gph is a mag 50?

edit.

5000? holy moly dude. whats your setup that can handle 5000 gph?
 
My indoor pond is the same way. The pumps usually heat the water to about 74F on there own. There are still some heaters in there to prevent the water temperature dropping too low. The room where the pond is is an uninsulated garage so room temperature can get pretty cold depending on the time of year.
 
I used the Mag 50 split into two out puts one flows into an over head filter and the other goes back into the tank for circulation. The funny thing is the pump is hooked up in line and when I touch it, it doesn't seem to hot; I mean no hotter then my Quite one 2200 where.

pharmaecopia Thats good to hear, will be setting up a 500 Gallon in the garage because I have no place else to put it.

All my fish hang out by the circulation return and surf the current, but there is nothing as funny as watching a 10" Oscar surfing the current.
 
Wow, 84F!? I would be worried that the pump would overheat the tank when summer rolls around.

You might want to consider getting a more efficient pump (the Mag 50 draws 475 Watts!) and running heaters separately from your water circulation. Using the pump as the heater doesn't give you much control over water temps.
 
The temp does drop during water changes but not to much, use heated water to do the changes. I have water lines ran to the tank so I can mix water at just a bit above normal temp so the water temp doesn't have much fluctuation. Plus I have heaters they just don't come one, I have 600watts of heaters in the tank, during the winter I run 900 watts.

I never intended to do a system where the pump is a heater, and only found out after the fact the pump was heating my tank so much. @ 475 watts it is not the most effect pump for sure, but its also not way over board I figure its out put is close to the power of a hammer head that runs on 334 watts.

This pump was meant for my 500 gallon tank but as that tank is empty I figure I would give my current setup a boost. moving from 1000gph to 5000gph has helped keep the tank cleaner and has helped the plants consume more the the nitrates.
