The Wacker Neuson Head is a genuine OEM component designed for the E 1250 and HSH 380 series hydronic surface heaters. Sourced directly from Wacker Neuson, this part meets the original engineering standards specified for LP/NG-fueled hydronic heating systems used in cold-weather concrete curing and ground thawing applications. Confirmed fitment spans the E 1250S, E 1250P, and E 1250B hydronic heaters as well as the HSH 380S and HSH 380B models. Ordering by part number ensures you receive the correct head assembly for your specific unit.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's original material and dimensional specifications, ensuring the head seals, connects, and performs exactly as the system was designed to operate.
- Direct-Fit Replacement — Engineered to drop into the same mounting position as the original, with matching port geometry and sealing surfaces for a leak-free installation on compatible units.
- Broad Series Compatibility — Fits the E 1250S, E 1250P, and E 1250B hydronic heaters (LP/NG) as well as the HSH 380S (with generator) and HSH 380B (without generator), covering both the E 1250 and HSH 380 product families.
- Critical to Heating System Integrity — The head is a core pressure-boundary component; a worn, cracked, or improperly seated head can cause fluid loss, pressure drop, and complete heating output failure on the jobsite.
- Fuel System Safety — As a pressure-side component on a gas-fired hydronic system, using the correct OEM head is essential for maintaining safe operating pressures and preventing hazardous fluid or gas leaks.
The head on a hydronic surface heater forms a sealed pressure boundary within the heating circuit, containing the fluid as it is heated and circulated through hoses and heating blankets to warm concrete slabs, frozen ground, or cold-weather cure zones. It is a primary structural and sealing component — if it cracks, warps, or develops a leak, the system loses pressure, heat output drops, and the heater may shut down entirely. Keeping this component in sound condition is essential for consistent, safe heating performance throughout the duration of a cold-weather pour or thaw cycle.
