Hot Water Delivery System Applications
The Armstrong Astro Express 2 system 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 for new housing construction.
