Domestic water distribution in standard two-pipe plumbing installations
The Armstrong Astro 2 hot water re-circulation system automatically circulates water through domestic water pipes. This ensures that hot water is available instantly at every tap throughout a residence. From a cost and environmental point of view, far less water is wasted each time a hot water faucet is opened – saving an average of 12,000 gallons of water annually for a typical four-person household. Ideal for retrofit applications.
Lead-free bronze or stainless steel (pump casing), ceramic (pump shaft and bearings), PEI (impeller), EPDM (bearing seals)
Max water temp 230°F (110°C)
