Upgrade to energy-efficient hot water circulation in residential buildings more quickly.
The compact Wilo-Yonos PICO-Z is the ideal replacement pump for upgrading domestic hot water systems in single-, two-, and multi-family homes to energy-efficient circulation pumps. This high-efficiency pump features a thermal insulation shell and offers a high level of hygienic safety thanks to its stainless steel housing. Electrical installation is quick and easy using the Wilo-Connector. Replacing the Wilo-Star-Z is straightforward, thanks to equivalent pump models and the "n-cst" continuous control mode for selecting the correct performance curve. With automatic and manual restart functions and a pump venting function, the Wilo-Yonos PICO-Z ensures all standard features required for reliable operation.
