The Wacker Neuson Probe 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. As a direct factory replacement, this probe is manufactured to the exact specifications required to maintain accurate temperature sensing and system control in Wacker Neuson's hydronic heating equipment. Sourcing the genuine OEM part ensures proper signal output and compatibility with the heater's control system without any guesswork on fit or function.
Key Features
- Calibrated Sensing Accuracy — Engineered to deliver precise temperature readings that the heater's control system depends on for safe and consistent heat output.
- Genuine OEM Quality — Sourced directly from Wacker Neuson, this probe meets the original design tolerances for signal response and material durability in freeze-condition environments.
- Direct Drop-In Replacement — Designed to connect into the existing probe port with no adapters or modifications, restoring system function quickly on the worksite.
- Broad HSH and E-Series Compatibility — Fits the HSH700G, HSH350, HSH650, HP252, E700M, and E2200 Ground Heater, covering a wide range of Wacker Neuson hydronic surface heating equipment.
- Critical for Cold-Weather Concrete Protection — A functioning probe keeps the heater operating within the correct temperature range, protecting freshly poured concrete from freezing during curing in cold-weather conditions.
- Fuel System and Burner Safety — Because the probe directly influences burner cycling and overheat protection, using the correct OEM-spec component is essential for safe heater operation.
The probe in a hydronic surface heater is a temperature-sensing component that monitors fluid or surface temperatures and sends readings back to the heater's control unit. This data tells the system when to fire the burner, when to cycle down, and when to shut off to prevent overheating — keeping the heating loop running within a safe and effective range. When the probe fails or reads inaccurately, the heater may fail to maintain target temperatures, cycle erratically, or trigger fault shutdowns, which can compromise concrete curing operations in cold-weather conditions.
