Overview
Grundfos UP and UPS (VersaFlo) circulators are the wet-rotor workhorses of residential and light commercial heating and hot water. UP models run at one speed, UPS models at three; UPSe models use an ECM motor. Cast iron housings serve closed heating loops; stainless steel (S) and bronze (B) housings serve domestic hot water. TLC models come with a timer and line cord for recirculation.
