The Wacker Neuson Sensor is a genuine OEM component designed for the E1250 and HSH 380 series hydronic surface heaters. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original sensor installed at the factory, ensuring proper system integration across LP/NG, diesel, and premium configurations. Compatibility spans the E1250S, E1250B, E1250P, HSH 380S, and HSH 380B model variants, covering both standard and generator-equipped units. When it's time for a repair, choosing the correct OEM part number — — is the most reliable way to restore your heater to full operating condition.
Key Features
- OEM-Spec Signal Accuracy — Engineered to deliver the correct output readings that the E1250 and HSH 380 control systems depend on for proper heater regulation.
- Direct-Fit Replacement — Designed to plug into the existing sensor harness and mounting location, matching the original connector configuration without adaptation.
- Broad Model Coverage — Fits E1250S, E1250B, and E1250P hydronic heaters as well as HSH 380S and HSH 380B units, across LP/NG, diesel, and generator-equipped variants.
- Restored Heating Performance — A failed or drifting sensor can cause erratic temperature control or system shutdowns; replacing it with part 5200015488 restores consistent, stable heat output.
- Fuel System Safety Relevance — In heating equipment, sensor accuracy is directly tied to fuel regulation and combustion control — using a correctly specified OEM sensor supports safe, code-consistent operation.
A sensor in a hydronic surface heater monitors a critical operating parameter — typically fluid temperature or system pressure — and relays that data to the control unit to regulate heating output. When the sensor reads correctly, the heater can maintain consistent temperatures and shut down safely when limits are reached. A worn, damaged, or out-of-spec sensor can cause the unit to overheat, under-perform, or trigger false fault shutdowns, interrupting curing or freeze-protection work on the jobsite.
