Wilo-Varios PICO-STG

The most versatile replacement pump of all time.

The Wilo-Varios PICO-STG is the universal replacement solution in the heating, air conditioning and cooling sector for residential dwellings, as well as for solar and geothermal installations. It offers either standard mode or external control mode, and the settings of the pump it replaces can be easily imported using the Sync assistant. Its compact construction and the adoption of characteristic curves from the old pump with the new synchronisation function make installation and commissioning particularly easy. And with the Green Button Technology the operability is highly convenient.
