Product Description

Astro-250SS circulator with timer, aquastat & 6 ft. line cord conserves energy and eliminates maintenance. Armstrong's Astro 2 Circulator is intended for circulating water or ethylene glycol solutions in closed hydronic or solar heating systems. It is designed with no mechanical seals or couplers to replace and no lubrication is required. Automatically circulates 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.  All systems are assembled, wired, tested, and then shipped from the factory, ready for installation.
