On this page, WILO Yonos PICO 1.0 15/1-4-130 Heating Circulation Pump is compared with three alternative heating circulation pumps: WILO Yonos PICO 1.0 25/1-4-130 Heating Circulation Pump, WILO Yonos Pico 2.0 25/1-4 High-Efficiency Glandless Circulation Pump, and Circulation pump Grundfos ALPHA1 25-60 130 with 130 mm port-to-port length for heating systems. All units are engineered for water circulation in residential heating applications and focus on high energy efficiency, but they differ in pipe connection diameters, product generations, maximum head height, and brand alternatives like Grundfos.
⚙️ The specification comparison covers core characteristics such as product type, intended use, port-to-port length, head pressure, and pipe connection sizes to help determine compatibility with your heating layout.
| Parameter | WILO Yonos PICO 1.0 15/1-4-130 | WILO Yonos PICO 1.0 25/1-4-130 | WILO Yonos Pico 2.0 25/1-4 | Grundfos ALPHA1 25-60 130 | Practical significance |
|---|
| Product type | Circulation pump | Circulation pump | Circulation pump | Circulation pump | All products serve the same core function of moving heat transfer fluid through heating circuits. |
| Brand | WILO | WILO | WILO | GRUNDFOS | Choosing between Wilo and Grundfos depends on brand preference and system compatibility. |
| Port-to-port length | 130 mm | 130 mm | Not specified | 130 mm | A 130 mm length simplifies replacement in compact existing piping installations. |
| Head / Performance | 1–4 m | 1–4 m | 1–4 m | Up to 6 m (ALPHA1 25-60) | The Grundfos model provides a higher maximum head suitable for more demanding circuit layouts. |
◎ The suitability and use case analysis shows which model is best suited for specific installation requirements and operational needs.
| Use case | Recommended product | Why |
|---|
| Replacing a pump in a space-constrained system requiring a 130 mm length and 1–4 m head | WILO Yonos PICO 1.0 15/1-4-130 | Fits physical dimensions and performance requirements perfectly for standard residential setups. |
| Installation in piping networks requiring a different connection diameter while keeping a 130 mm length | WILO Yonos PICO 1.0 25/1-4-130 | Offers matching efficiency and head characteristics tailored to a different pipe sizing standard. |
| Utilizing newer generation technology within the Yonos Pico product line | WILO Yonos Pico 2.0 25/1-4 | Incorporates updated energy-saving features within the same pump family. |
| Heating systems requiring a higher maximum head pressure of up to 6 meters | Circulation pump Grundfos ALPHA1 25-60 130 | Delivers greater hydraulic performance and higher head for maintaining flow in complex loops. |
WILO Yonos PICO 1.0 15/1-4-130 is best suited for standard residential heating systems requiring a 130 mm port-to-port length and a head of up to 4 meters. Choose it if you need a reliable, compact, and energy-efficient circulation solution. Competitor products are more appropriate when your system requires a different pipe connection size, a newer generation model, or a higher head pressure of up to 6 meters.
