The AB 110V 130W hot water recirculating pump is a versatile circulator designed for hydronic radiant heating, boilers, solar water heaters, floor heating systems, and domestic hot water recirculation. It excels in speeding up hot water delivery to faucets, reducing cold water waste and wait times, making it perfect for homeowners or small commercial setups seeking reliable circulation without complex plumbing changes.
Standout features include three manual speed settings delivering 13 GPM max flow and up to 24 feet of head, with power options from 55W to 130W for energy efficiency. The self-lubricating wet rotor ensures quiet operation, while the ceramic bearings and PES impeller handle temperatures up to 230°F and pressures to 145 PSI. In real-world use, it provides consistent pressurization for side-arm heat exchangers, radiant manifolds, and pool heaters, promoting faster heating cycles.
Build quality shines with a heavy-duty cast iron pump head and casing, full copper motor coil, and included 1-inch FNPT flanges, gaskets, bolts, and nuts for straightforward installation using just a wrench. The 3.46-foot cord with standard US plug adds convenience, though the 7-pound weight might require assistance during mounting.
Potential drawbacks include its 110V requirement, limiting use in some international or high-voltage setups, and the need for occasional checks on cast iron to avoid corrosion in humid environments. No mechanical seals mean low maintenance, but proper installation is key.
Overall, this pump offers excellent value for efficient, durable hot water circulation. It earns high marks for performance and ease, ideal if you prioritize energy savings and quiet reliability in heating systems.
