Astro 2 HWR Systems 3 Pipe Install

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.

Problem:

Heated water cools rapidly in domestic hot water distribution pipes, even when properly insulated. When hot water is desired, the common practice is to run cooled water down the drain until hot water reaches the tap. A typical family of four can waste over 90 hours and 12,000 gallons of sanitized water per year while waiting for hot water at the tap. 

Solution:

Armstrong Astro 2 Hot Water Re-circulation systems automatically circulate water through domestic hot water distribution pipes. This helps to ensure that everyone in the household has ‘instant’ hot water at the tap when they need it, while also helping to conserve water and save water heating energy costs. Models equipped with an aquastat save even more energy.
