The Wacker Neuson Relay is a genuine OEM component designed for the E1100, E2200, E3000, E3000 ES, E5000, Pureheat, and CH5000 series hydronic surface heaters and ground heaters. As a direct factory replacement, this relay matches the exact electrical specifications of the original part, ensuring seamless integration with the heater's control system. It is compatible across a wide range of configurations including ground heater, hydronic surface heater, and lift bail variants. Always confirm your machine number against the fitment list to ensure you are ordering the correct relay for your specific unit.
Key Features
- Genuine OEM Electrical Specification Match — Sourced directly from Wacker Neuson, this relay meets the original switching capacity, coil voltage, and contact rating required by the heater's control circuit — no guesswork on compatibility.
- Direct Drop-In Replacement — Engineered to the same mounting footprint and connector configuration as the original, allowing straightforward installation without re-wiring or adapting terminals.
- Broad Series Fitment — Compatible with E1100, E2200, E3000, E3000 ES, E5000, Pureheat, and CH5000 hydronic heater models across ground heater and surface heater configurations, including lift bail and generator-equipped variants.
- Restores Heater Control Function — A failed relay can prevent the burner or pump circuit from energizing, causing the heater to fail to start or shut down unexpectedly. Replacing it restores correct on/off switching and keeps the heating system operating through cold-weather work cycles.
- Electrical Safety Assurance — Using the correct OEM relay ensures the switching circuit operates within its rated load, protecting downstream electrical components from overcurrent conditions caused by an out-of-spec substitute.
A relay is an electrically operated switch that allows a low-power control signal — such as the signal from the heater's thermostat or control board — to switch a higher-power circuit on or off, such as the burner ignition or circulation pump. In a hydronic heater, the relay acts as the bridge between the control logic and the working components that generate and distribute heat. When a relay fails, it can stick open (preventing the circuit from energizing at all) or stick closed (preventing the circuit from shutting off), both of which disrupt heating performance and can cause damage to other system components if left unaddressed.
