Default Re: yar...any1 tried one o these

I'd be interested to see how much heat it adds.
Connect the inlet to the outlet and insulate the tubing and pump head as much as possible. Measure the water volume in this loop.
Turn pump on and measure the temp of the water over time: enough time to get a reasonable increase in temperature.
Do the maths for the volume of water and temp gain versus time and you'll get an approximate Watts added figure.
