The Wacker Neuson Rectifier is a genuine OEM component designed for the E-series and HSH-series hydronic surface heaters and ground heaters, including the E1100, E2200, E3000, E3000 ES, E5000, HSH350, HSH650, HSH700, HP252, Pureheat, E700M, and CH5000 families. As a direct OEM replacement, part is sourced from Wacker Neuson and built to the exact electrical specifications of the original component. This rectifier serves a critical function in the onboard electrical system, ensuring the generator and control circuits receive properly conditioned DC power. Confirm your machine's model number against the fitment list before ordering to ensure this is the correct part for your configuration.
Key Features
- Correct Output Specification: — Manufactured to the original voltage and current ratings for Wacker Neuson hydronic heater electrical systems, ensuring the control board and pump circuits receive stable, properly rectified DC power.
- Genuine OEM Part: — Sourced directly from Wacker Neuson, part number 5000166564 carries full OEM traceability and meets the original design intent for these heater platforms.
- Broad Fitment Across the Heater Lineup: — Covers a wide range of E-series ground heaters and hydronic surface heaters (E1100, E2200, E3000, E3000 ES, E5000), plus HSH350, HSH650, HSH700, HP252, Pureheat, and CH5000 models.
- Protects Downstream Electrical Components: — A correctly functioning rectifier prevents voltage irregularities that can damage the controller, solenoids, and circulation pump — keeping the entire heating system operating as intended.
- Electrical Safety Compliance: — Using the correct OEM rectifier maintains the integrity of the heater's electrical system, reducing the risk of overloads, erratic control behavior, or component failures caused by out-of-spec power conversion.
- Drop-In Replacement: — Matches the original mounting and wiring connections on supported models, allowing straightforward installation without electrical rework.
A rectifier converts alternating current (AC) produced by the onboard generator into the direct current (DC) required by the heater's control electronics, solenoids, and circulation pump. Without a properly functioning rectifier, the heater's low-voltage control circuits receive unregulated or incorrect power, which can cause erratic operation, failure to ignite, pump malfunctions, or damage to the control board. Replacing a failed or degraded rectifier restores correct power conversion and is often the first step when diagnosing electrical faults on Wacker Neuson hydronic heaters and ground heaters.
