About This Product

Heating system needing an upgrade? This B&G NRF-22 circulator pump is built tough with a cast iron body that can handle years of service in your boiler or outdoor wood furnace system. The package includes both the pump AND a pair of 1-inch cast iron flanges, so you have everything needed for a proper installation. These pumps are workhorses designed for continuous operation in hydronic heating systems, moving hot water efficiently through your baseboards, radiators, or underfloor systems. The cast iron construction resists corrosion and handles high temperatures without issues. Installation is straightforward if you're familiar with plumbing work - just make sure to match the flow direction and electrical connections properly. This particular model is commonly used in outdoor boiler setups where reliability is crucial during cold months. The flanges make connecting to your existing piping system much simpler with standard fittings. These pumps move a solid amount of water while maintaining good pressure for multi-zone systems. If your current pump is noisy, struggling to maintain temperature, or just plain old, this replacement will get your heating system performing like new again. The cast iron body dissipates heat well and stands up to the demanding conditions of boiler applications. Whether you're a homeowner maintaining your own system or a professional installer, having a reliable circulator pump like this on hand can prevent those emergency no-heat situations when winter hits hardest. Proper installation is key though - if you're not comfortable with plumbing and electrical work, definitely call in a professional to handle the swap.
