NEW

Maximum hygiene and energy efficiency in domestic hot water circulation.

The Wilo-Stratos PICO-Z is the ideal circulator for domestic hot water supply in semi-detached houses or multi-family complexes, as well as smaller buildings with a mix of residential and commercial use. With a stainless steel pump housing and the ability to detect thermal disinfection in the domestic hot water tank, it offers the greatest possible hygienic safety for the entire domestic hot water system. Thanks to the Wilo-Connector, it is quickly installed electrically and can be commissioned in factory settings with a click. The high-efficiency pump equipped with EC motor, together with the manual or temperature-controlled operating mode, offers all options for reducing individual power consumption. The large colour display, clear settings menu in combination with the Green Button Technology make the pump very convenient to operate.
