The Wacker Neuson Electrode is a genuine OEM component designed for the HSH and E-series hydronic surface heaters, including the HSH700G, HSH350, HSH650, HP252, E700M, and E2200 Ground Heater models. As a direct OEM replacement, this electrode is manufactured to the exact specifications required by Wacker Neuson, ensuring correct ignition geometry and reliable spark performance in demanding cold-weather heating applications. Confirmed fitment spans the full range of Wacker Neuson hydronic surface heater platforms, so you can order with confidence knowing part number is the correct replacement for your unit.
Key Features
- OEM Ignition Specification: — Manufactured to Wacker Neuson's exact electrode gap and material spec, ensuring consistent spark output and reliable burner ignition in cold-weather conditions.
- Direct Drop-In Replacement: — Matches the original mounting configuration and terminal connection of the factory electrode for a straightforward swap during routine service.
- Broad HSH & E-Series Fitment: — Compatible with the HSH700G, HSH350, HSH650, HP252, E700M, and E2200 hydronic surface heater models, covering both 50Hz and standard configurations.
- Consistent Burner Performance: — A properly functioning electrode delivers a clean, reliable ignition arc; a worn or fouled electrode leads to hard starts, misfires, and incomplete combustion that can interrupt surface heating operations.
- Fuel System Safety Compliance: — Correct electrode specification is critical in combustion-based heating equipment; using a genuine OEM part maintains proper ignition timing and reduces the risk of unburned fuel accumulation.
The electrode is the ignition component in the burner assembly of a hydronic surface heater. It generates the high-voltage spark that ignites the fuel-air mixture at startup, initiating the combustion cycle that heats the fluid circulated through the heater's hose network. Without a functioning electrode, the burner cannot light, leaving the heater unable to produce heat — a critical failure on cold-weather concrete curing or ground thawing jobsites. Over time, electrodes can erode, foul with carbon deposits, or crack, all of which degrade spark quality and cause intermittent or failed ignition sequences.
