I ran across this item at Costco today (link at bottom) made by Watts. It is a hot water recirculator (pump included) for about $180. You install it near your hot water heater and it is supposed to give you instant hot water and save you over 10,000 gallons of water per year. Couple of questions:

1) Is it legit and will it really save water and energy (this is my primary objective for installation)?
2) Is it easy for someone w/very little (I don't want to have to solder anything myself) to install?
3) If it isn't that easy to install, what kind of price would I pay for a plumber to install it?
