The Wacker Neuson Expansion Tank is a genuine OEM component designed for the HP252 and Pureheat Hydronic Heater series, including Oil Burner, Gas Burner, and Diesel-fired configurations. As a direct OEM replacement, this part is manufactured to the same specifications as the original, ensuring a proper fit within the hydronic heating system. It is compatible across multiple Pureheat variants, making it a reliable choice for fleet operators running mixed Pureheat configurations. Always verify your model number against the fitment list before ordering to confirm compatibility.
Key Features
- Genuine OEM Pressure Containment — Manufactured to Wacker Neuson's original pressure and volume tolerances, ensuring the tank absorbs thermal expansion without allowing system pressure spikes that could damage hoses or fittings.
- Direct Drop-In Replacement — Matches the original mounting points and connection ports on HP252 and Pureheat Hydronic Heater units, allowing straightforward installation without modification to existing plumbing.
- Broad Pureheat Series Compatibility — Fits the HP252 as well as Pureheat Hydronic Heaters in Oil Burner, Gas Burner, and Diesel configurations, covering a wide range of Wacker Neuson hydronic heating equipment.
- Protects System Integrity — A failed or compromised expansion tank causes erratic pressure fluctuations that can force coolant loss, trigger safety shutdowns, and put undue stress on the entire hydronic circuit.
- Fuel and Fluid Compatibility — Constructed from materials suited to the hydronic fluid environment found in indirect heating systems, maintaining structural integrity through repeated heat-and-cool cycles.
An expansion tank absorbs the increase in fluid volume that occurs as the heating fluid warms up inside a closed hydronic system. Without a properly functioning expansion tank, rising fluid pressure has nowhere to go, which can force open pressure relief valves, push fluid out of the system, or strain hose connections and seals. Over time, a degraded or waterlogged expansion tank loses its ability to buffer these pressure changes, leading to inconsistent heater performance, unexpected shutdowns, and accelerated wear on other system components.
