The Wacker Neuson Electrical Box is a genuine OEM component designed for the HSH hydronic surface heater series and companion power/heater units, including the HSH700G, HP252, E2200 Ground Heater, HSH650, and E700M Hydronic Surface Heater. As a direct OEM part, it is manufactured to the exact specifications required by Wacker Neuson for correct operation of the electrical control system in these machines. The ships as a complete electrical box assembly, making it a straightforward swap for a damaged or failed unit. If your hydronic surface heater is showing electrical faults, loss of control function, or visible damage to the control enclosure, this is the part to restore it to full working condition.
Key Features
- OEM-Spec Electrical Integrity — Manufactured to Wacker Neuson's exact voltage and circuit specifications, ensuring correct control function without guesswork on compatibility.
- Complete Box Assembly — Supplied as a full electrical box unit for a clean, direct replacement of the original enclosure and internal components.
- Broad HSH & Heater Unit Fitment — Confirmed fit across the HSH700G, HSH650, HP252, E2200 Ground Heater, and E700M Hydronic Surface Heater models.
- Restores Full Control Operation — A functioning electrical box keeps all heater controls and safety circuits operating correctly; a failed or damaged unit can render the entire heater inoperable on site.
- Electrical Safety Compliance — Using the correct OEM enclosure maintains proper insulation, grounding, and circuit protection as designed — critical for safe operation of any electrically controlled heating system.
The electrical box on a hydronic surface heater serves as the central control hub, housing the wiring, terminals, and switching components that manage heater operation, temperature regulation, and safety shutoff functions. When the electrical box is damaged, corroded, or internally failed, the heater may lose the ability to start, maintain set temperatures, or respond to operator controls. Replacing it with a genuine OEM unit like the Wacker Neuson 5000166788 ensures all electrical pathways and protective circuits are restored exactly as originally designed.
