The Taco 0010 is designed for a wide range of large residential or light commercial water circulating applications. Typical uses include hydronic heating, radiant heating, primary-secondary loops, indirect water heaters, chilled water cooling, and potable hot water systems. The Stainless Steel 0010 is designed for all open-loop, fresh water systems. The unique replace-able Cartridge contains all of the moving parts and allows for easy service, instead of replacing the entire Circulator. Compact, direct-drive, low power consumption design makes it ideal for high-efficiency jobs.
