The Wacker Neuson Left Rear Door is a genuine OEM enclosure component designed for the E1250 and HSH380 series hydronic surface heaters. Sourced directly from Wacker Neuson, this door matches the original in material, fitment, and finish — ensuring the unit's enclosure is properly sealed and protected in the field. Part number is confirmed compatible across the E1250S, E1250B, and E1250P variants, as well as HSH380S and HSH380B models in both fuel configurations. Whether you're restoring a damaged enclosure or replacing a worn door, this genuine OEM part delivers the exact fit the machine was built around.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's original enclosure specifications, with matching panel geometry, hinge points, and surface finish for a flush, secure closure.
- Direct Drop-In Replacement — Mounts to the existing hinge and latch hardware on the rear enclosure — no trimming, drilling, or modification to the cabinet frame needed.
- Broad HSH and E1250 Series Compatibility — Fits E1250S, E1250B, and E1250P hydronic heaters across LP/NG and Diesel fuel variants, plus HSH380S and HSH380B models with and without generators.
- Enclosure Integrity Restored — A properly fitted rear door keeps internal components shielded from moisture, debris, and jobsite contamination — a damaged or missing door exposes burner and heat exchanger components to the elements.
- Fuel-Configuration Coverage — One part number spans LP/NG and Diesel-fueled variants across both the E1250 and HSH380 families, so there's no risk of ordering the wrong door for your unit's fuel type.
The left rear door is a structural panel on the outer enclosure of Wacker Neuson hydronic surface heaters, forming part of the protective cabinet that houses the burner assembly, heat exchanger, and fluid circulation components. It serves as a weather and impact barrier, keeping internal systems protected during operation and transport on active jobsites. When the door is damaged, bent, or missing, internal components are left exposed to moisture ingress and physical damage — potentially compromising burner performance, accelerating corrosion of heat exchanger surfaces, and creating unsafe operating conditions for the heater as a whole.
