application
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 heat-
ing energy costs. All systems are assembled, wired, tested
and then shipped, ready for installation.
