Yep, you have to set the thermostat on the hot water heater so that it is 
LOWER than the output of the heat pump.  In the case of my system that is 125 
degrees F. or a little lower.  When the water goes from the water heater tank to 
the kitchen or the laundry room, it might be 100 degrees, if that by the time 
it comes out of the faucet or into the washer.  That is just not hot enough to 
do any good.  And, yes, the professionals did agree that if I wanted water 
that was more than just "warm" the recovery system would not work.  It was free 
and so was the installation so I didn't worry about it and just turned the 
blamed thing off.

By the way, the heatpump system I have is over 10 years old and is rated 
something like 85% efficient, not up to the current standard but it still does a 
good job and, as I mentioned earlier, it costs me less than any of my neighbors 
on natural gas.  It cost me $4,400.00 USD for the unit and installation.
