The Wacker Neuson Conversion Control Kit is a genuine OEM component designed for the E 1250 and HSH 380 series hydronic surface heaters, including the E 1250S, E 1250P, E 1250B, HSH 380S, and HSH 380B models. As a direct OEM replacement, this kit is sourced from Wacker Neuson and built to the same specification as the original part — ensuring a correct, trouble-free installation in the field. Whether you are converting fuel type or restoring control function on an existing unit, the delivers the exact components needed to get your heater back to full operation across the LP/NG-compatible E 1250 and HSH 380 families.
Key Features
- OEM-Matched Control Components — Each component in this kit is manufactured to the precise electrical and mechanical tolerances of the original Wacker Neuson control system, ensuring correct signal routing and reliable fuel conversion switching.
- Direct Drop-In Installation — Engineered to connect to existing harness points and mounting locations on compatible E 1250 and HSH 380 units, with no improvised adapters or field fabrication needed.
- Broad Fitment Across the HSH Family — Confirmed compatibility with the E 1250S, E 1250P, and E 1250B hydronic heaters, as well as the HSH 380S (with generator) and HSH 380B (without generator) — covering both LP and natural gas configurations.
- Restores Proper Fuel Conversion Control — A worn or malfunctioning control kit can cause improper fuel switching, burner instability, or failure to maintain target output temperatures; replacing it with a correct OEM kit restores the heater's designed operating profile.
- Fuel System Safety Compliance — Because this kit governs fuel-type conversion and burner control, using the correct OEM-specified components is essential to maintaining safe operation and proper combustion management on LP/NG-capable units.
The Conversion Control Kit manages the fuel-type switching and burner control function within Wacker Neuson's hydronic surface heaters. It enables the heater to operate correctly on either liquid propane or natural gas by ensuring the control system delivers the right signals and settings for the selected fuel source. When this kit is worn, damaged, or incorrectly configured, the heater may exhibit inconsistent burner behavior, fail to reach or hold set temperatures, or refuse to switch fuel modes — all of which directly impact the efficiency of concrete curing or cold-weather heating applications on the jobsite.
