I'm considering this for the bathroom upstairs. I found this article:
https://www.thespruce.com/hot-water-reci...em-2719054
and if I'm understanding it correctly it is possible to plumb one in using the existing lines, that is without having to add an additional line to create the hot water loop. The kids already complain that the water takes a while to warm up. I still need to investigate cost, etc before I make a final decision. I think I would do the pump under the sink upstairs option. It would be easier to install and access if needed - the heater requires emptying a closet and unscrewing a panel to get to it. I did have a question as to the water that gets put into the cold side, where does it go? Back into the water heater? I guess it would have to, given that the pump is pulling water from the heater on the hot side.
