Wilo Star-Z 20/5-3 Hot Water Recirculation Pump, 150mm

The Wilo Star-Z 20/5-3 is a recirculation pump for domestic hot water systems, keeping hot water circulating through the pipework so it arrives at the tap immediately when opened, rather than after a delay. Its bronze housing delivers a nominal flow of around 1.48 m3/h and up to 4.57m of head, drawing 0.4A at a 90W power input. The compact 150mm installation length suits retrofit into existing pipework.
