The Wacker Neuson Valve is a genuine OEM component designed for the E3000, E2200, E1100, and E1250 series hydronic surface heaters and ground heaters. As a factory-sourced part, it meets the exact material and dimensional standards established for these electric heating systems, ensuring proper fluid control within the heating circuit. This valve is confirmed to fit across a wide range of E-series configurations, including models E3000, E2200, E1250S, E1100, E3000ES, E1250B.
Key Features
- Genuine OEM Fluid Control Accuracy — Manufactured to Wacker Neuson's exact tolerance specifications for the valve seat and flow characteristics, ensuring consistent fluid regulation within the hydronic circuit.
- Direct-Fit Replacement — Part number 5000172422 matches the original valve installation interface on E-series heaters, dropping into the existing plumbing connections without modification to the circuit.
- Broad E-Series Compatibility — Fits E3000, E3000ES, E2200, E1100, E1250S, E1250B, and E1250P models across ground heater and hydronic surface heater configurations, including lift bail and generator-equipped variants.
- Protects Heating Circuit Performance — A correctly functioning valve maintains proper coolant or glycol flow through the heating loop; a worn or leaking valve can cause uneven heat distribution, pressure loss, or system shutdown.
- Fluid System Integrity — In a hydronic heating system, valve condition is critical to maintaining sealed-circuit pressure; using a genuine OEM valve prevents premature leaks or seat failures that can compromise heating output on cold-weather jobsites.
In a hydronic surface heater or ground heater, the valve controls the flow of heated fluid through the system's plumbing circuit, directing or shutting off coolant or glycol to maintain the correct heat output and system pressure. It plays a key role in keeping the heating loop balanced and responsive to temperature demands. When a valve fails — through seat wear, corrosion, or internal leakage — the system can lose pressure, deliver uneven heat, or trigger protective shutdowns, making timely replacement essential to uninterrupted cold-weather operations.
