The 595916 from Grundfos is a UP15-10SU7P/TLC Comfort System w/ Comfort Valve & Connectors, 3/4” NPT. This item is an all-in-one, easy to install solution for domestic hot water recirculation. It's great for existing construction and can be easily integrated without the need for running a separate line. The Comfort System includes a timer, line cord, comfort valve (#595926) and flexible connectors. It already comes with all of the necessary components, so there's no need to purchase extras. To get it working, connect the lines, plug it in and turn it on. The circulator pump is for open systems with max liquid temperatur of 150F.

How it works: 

The stainless steel circulator pump is installed directly onto the hot water discharge on the water heater. The comfort valve is installed at the fixture furthest from the water heater. The system uses the cold water line to return hot water to the water heater, thus saving on utility bills.
