The Wacker Neuson Brush is a genuine OEM component designed for the E1250S, E1250B, E1250P, HSH380S, and HSH380B series hydronic surface heaters. As a direct OEM replacement, this brush is sourced and specified to meet Wacker Neuson's original build requirements, giving you confidence that the part will install and perform exactly as intended. Compatible across multiple E1250 and HSH380 configurations — including diesel, natural gas, and LP/NG variants — this single part number covers a wide range of hydronic heater models in the field.
Key Features
- Genuine OEM Construction: — Manufactured to Wacker Neuson's original material and dimensional specifications, ensuring the brush delivers the correct contact pressure and conductivity for your heater's electrical system.
- Direct Drop-In Replacement: — Engineered to seat and connect exactly as the original, fitting into the brush holder without alteration across all compatible models.
- Broad Hydronic Heater Compatibility: — Fits E1250S, E1250B, and E1250P models in standard and premium configurations, as well as HSH380S and HSH380B units across diesel, natural gas, and propane fuel variants.
- Sustained Electrical Contact Performance: — A worn or degraded brush can cause intermittent motor operation or complete failure of the heater's circulation system; replacing it promptly restores consistent, uninterrupted function.
- Verified Part Number Traceability: — Part number 5200017412 is the authoritative Wacker Neuson reference, making fitment verification straightforward when cross-referencing your machine's serial number or parts manual.
A brush is a small carbon or carbon-composite block that maintains sliding electrical contact between a stationary terminal and a rotating component — typically the motor's commutator or slip ring — inside the hydronic heater's circulation pump or blower motor. It carries the current needed to keep the motor spinning and transfers it without a fixed connection, allowing continuous rotation. When a brush wears down too far, electrical contact becomes inconsistent, leading to motor hesitation, reduced heat output, or a complete loss of fluid circulation — which in cold-weather concrete curing or ground thawing applications can compromise the entire heating process.
