Circulator Pump
A circulator pump is a device that moves hot water through heating systems in buildings, like radiators and heated floors. Think of it as the heart of a heating system that keeps warm water flowing to maintain comfortable temperatures. It's an essential component in residential and commercial heating systems, and professionals who work with these pumps need to know how to install, maintain, and repair them. You might also hear them called "heating circulators" or "hydronic pumps." They're commonly found in boiler systems, radiant floor heating, and other hot water heating applications.
