595916 - Comfort System Hot Water Recirculation Pump - 3/4" NPT 115 Volt

Grundfos Comfort System 595916 - UP 15-10 SU7P/TLC 

The Grundfos COMFORT System provides all the components needed to retrofit a hot water recirculation system in a home without a dedicated return line. 

Grundfos Comfort System for hot-water recirculation delivers hot water in an instant to taps and showers in private homes. The water circulation system eliminates cold water line runoff at the faucet using a bypass valve and pump with a timer to control water flow while delivering instant hot water.

The Grundfos Comfort System brings both comfort and savings to the retrofit market without the need for a dedicated return line.

The stainless steel circulator with timer, installed at the water heater, helps pull water back to be heated and recirculated. The thermostatically controlled comfort valve, installed at the farthest fixture from the water heater, helps regulate the flow from hot water line to the cold-water line.

The Grundfos Comfort System is the ultimate in comfort and convenience as hot water is instantly available at sinks, appliances and bathroom faucets throughout the household.
