UP15-10SU7P/TLC Grundfos Comfort Series 1/25 HP Recirculator Pump (595916)

Grundfos Pumps is proud to bring the comfort and savings of hot water recirculation to the existing homes market with the Comfort Series Instant Hot Water System. The Comfort System includes a Grundfos UP15-10SU7/TLC circulator and the revolutionary Comfort Valve. The stainless steel circulator, complete with timer and 10-foot power cord, is installed directly to the hot water discharge on the water heater. The Comfort Valve is installed under the sink at the fixture furthest from the water heater, and the system uses the existing cold water line to return hot water to the water heater.

The Comfort System is designed to give homeowners the added comfort and convenience of instant hot water and reduce the amount of wasted water. Unlike our competitor's products, there are no pumps under sinks (and thus no power required under sinks), no return lines required, and no buttons to push. Set the timer on the Grundfos pump and stop waiting for hot water.

The Comfort valve is installed at the furthest fixture from the hot-water tank. With a built-in timer, the pump allows hot water to circulate along the loop through the valve using the cold-water side as a return line. As the temperature rises to 100 °F, the valve closes directing hot water to the tap, resulting in a constant availability of hot water.
