submersiable water pumps question??

[tasermebro]

Ina dwc setup with subpump in the rez (not recirculating/ebb&flow) will that cause the temps to rize??

Will a frozen 2 liter pop bottle help keep temps down thanks a lot??

yes temps....mabee for the 2 liters but..... it will become a job in itself

I've also been wondering about the submersibles creating heat... last time I saw someone ask about it, it went unanswered.

ya we had a submersible pump that got pretty hot. i tried to throw a frozen bottle in there when it came on about 3times a day. it worked pretty well.

Every submersible will create a certain amount of heat. It converts electricity into kinetic motion, and every time you convert from one kind of energy to another you lose some energy in the process, generally in the form of heat.

How much heat, that's hard to say. Some pumps are bound to create more heat than others. The average pump probably doesn't generate enough heat to worry about, depending on your reservoir size and how close you are to problem temperatures already.

The only way to know for sure is to test the specific pump in the specific application. Let it sit idle for a couple hours, check temperature, then run it normally for a couple hours and check temperature.
