Okay how do I convert to how much heat a pump will transfer to the water?

Mag Drive Water Pumps

Flow Rate: 500 GPH
Watts: 45

So is this pump giving off 45 watts into the water? Would this be like having a 45 watt heater in the tank?

The tank is 150 gallons that I am considering adding the pump.

Thanks

45watt would be the power consumption figure. ie approximately 45 volt-amps or less than a half amp at 120 volts or quarter amp at 240 volts. The actual heat it would give off is not usually listed, but it would be less than 45 watts as you would assume only some of the power would be emitted as heat, the rest would be used to move water. All you really know is the max heat possible should be 45 watts, but it would be less. In 150 gallons I don't think even 45 watts is very significant tho, is it?
 
Net effect, yes, it is the watts. Initially a portion of the watts are used to do work (lifting or moving water), but that energy imparted disipates as heat. Exactly as light energy from a bulb ends up a heat change eventually, along with the portion initially "lost" as heat.
 
Thanks.

I figure 45 or less watts won't affect the temp much in a 150 gallon stock tank.
