The Wacker Neuson Sensor is a genuine OEM component designed for the E1250S and E1250P hydronic heaters and HSH380S hydronic surface heaters. As a direct factory replacement, this sensor installs into the heating system exactly as the original, supporting accurate temperature monitoring and consistent system control across LP/NG and diesel-fueled configurations. Wacker Neuson genuine OEM parts are manufactured to the same specifications as the parts they replace, making the the most straightforward service option for these hydronic heating units. Compatible models include the E1250S Standard LP/NG, E1250P Premium Diesel, E1250P Premium LP/NG, HSH380S Diesel with Generator, and HSH380S Natural Gas/Propane with Generator.
Key Features
- OEM-Spec Signal Accuracy — Manufactured to the original output and response tolerances required by Wacker Neuson hydronic heating systems, ensuring the control circuit receives correct readings.
- Direct Drop-In Replacement — Matches the original connector type, thread spec, and mounting position for a straightforward swap with no adaptation needed on supported models.
- Broad Hydronic Heater Compatibility — Fits the E1250S and E1250P series hydronic heaters and HSH380S hydronic surface heaters across LP/NG, natural gas, and diesel fuel variants.
- Protects System Efficiency — A correctly functioning sensor keeps the heating system operating within its designed temperature range, preventing overcycling, output loss, or unplanned shutdowns on cold-weather jobsites.
- Fuel-System Safety Relevance — In heating equipment, a failed or drifting sensor can cause the system to misread fluid or exhaust temperatures, leading to unsafe operating conditions; replacing a suspect sensor promptly is a key part of routine heater maintenance.
The sensor in a hydronic heating unit continuously monitors fluid or system temperature and feeds that data to the control board, which uses it to regulate burner output and circulation. When the sensor drifts out of calibration or fails entirely, the control system loses accurate temperature feedback — this can result in erratic cycling, insufficient heat output, or the unit shutting down on fault codes. Replacing a worn sensor with a genuine OEM part like the Wacker Neuson 5200015410 restores accurate system feedback and brings the heater back to proper operating condition.
