Description
This hot water recirculation system, ALPHA 15-55 HWR-D LC with Comfort Valves, is a wireless push-button activated solution for homes that eliminates the need for a return line or electricity under the sink. It starts via remote activation when there is demand for hot water, using Bluetooth to circulate until reaching 102 °F or after 5 minutes of operation. The system includes a line cord, two activation push buttons, four thermal bypass valves, four hose kits, and one set of 3/4" bronze union isolation valve fittings.
