Provides domestic hot water with maximum hygiene and low energy consumption.
The Wilo-Stratos PICO-Z is the ideal circulation pump for domestic hot water systems in two-family homes, multi-family dwellings, and small mixed-use residential/commercial buildings. With its stainless steel pump housing and the ability to detect and support thermal disinfection, it ensures the highest level of hygienic safety for the entire domestic hot water system. The Wilo-Connector allows for quick electrical installation, and the factory settings enable immediate operation with just a single click. The high-efficiency pump, equipped with an EC motor and offering manual or temperature-controlled operating modes, provides various options for reducing individual power consumption. A large color display, a clear settings menu, and "Green Button Technology" make operating the pump highly convenient.
