Armstrong ASTRO Express 2 SSU Hot Water Recirculation Pump

This pump is designed for domestic water distribution in standard two-pipe plumbing installations.  It delivers hot water to the tap, recirculating cooled water back to the water heater via existing cold water piping.  In addition to providing the homeowner instant hot water access, the system also helps to conserve municipal drinking water resources and save metered water charges.  It's easy to install, and does not require special return piping to the water heater. This makes the Astro Express 2 system the ideal retrofit solution for existing residential buildings, and a cost-effective solution, when offered as an option in new home construction.  The pump is controlled by a 24 hour timer which allows homeowners to schedule delivery of hot water in 15 minute increments throughout the day.
