The Wacker Neuson is a genuine OEM Exhaust Baffle designed for the E1250S, E1250B, E1250P, HSH380S, and HSH380B hydronic surface heaters. As a factory-sourced component, it matches the original part in material grade and geometry, ensuring a correct drop-in fit within the exhaust path of the heater assembly. This part covers a broad range of fuel configurations — including diesel, natural gas, and LP/NG variants — across both standard and premium heater models. If your hydronic heater is showing signs of exhaust noise, heat loss, or combustion irregularity, replacing the exhaust baffle with part number restores proper flue performance.
Key Features
- OEM-Matched Exhaust Path Geometry — Manufactured to the original baffle profile so combustion gases are directed and attenuated exactly as the heater was engineered to operate.
- Direct Drop-In Replacement — Seats into the existing exhaust assembly without modification, maintaining correct clearances and mounting alignment on affected heater models.
- Wide Fitment Coverage — Compatible with E1250S, E1250B, E1250P, HSH380S, and HSH380B models across diesel, natural gas, and LP/NG fuel variants.
- Restores Combustion Efficiency — A worn or damaged baffle disrupts exhaust flow and can cause back-pressure issues, uneven heating output, and increased fuel consumption; a fresh OEM baffle brings performance back to spec.
- Exhaust Integrity for Enclosed-Space Use — Hydronic heaters are frequently operated in job trailers, slabs, and partially enclosed areas where a properly sealed and baffled exhaust path is essential for safe combustion gas routing.
The exhaust baffle is a structural insert positioned within the heater's flue or exhaust chamber. Its role is to control the direction, velocity, and backpressure of combustion gases as they exit the burner assembly, which directly affects heat transfer efficiency and overall burner stability. When the baffle deteriorates — through heat fatigue, corrosion, or physical damage — exhaust gases can bypass the intended flow path, reducing thermal output, increasing fuel waste, and potentially allowing combustion byproducts to escape in unintended directions. Replacing part 5200025141 with a genuine Wacker Neuson component ensures the exhaust system continues to function as designed across all supported E1250 and HSH380 heater configurations.
