The Wacker Neuson Overflow Bottle is a genuine OEM component designed for the E1250S and E1250P Hydronic Heaters, E2200 and E3000 Ground Heaters, HSH380 Hydronic Surface Heaters, and HI1000 Indirect Air Heater series. As a direct OEM replacement, part is manufactured to the same specifications as the original, ensuring a correct fit within the coolant or fluid reservoir system. This bottle is compatible across a wide range of Wacker Neuson heating equipment configurations, including LP/NG, Diesel, and generator-equipped variants of the E1250, E3000, and HSH380 families.
Key Features
- Genuine OEM Construction — Manufactured to original design tolerances, ensuring correct fluid capacity and proper fitment within the reservoir system of Wacker Neuson heating equipment.
- Drop-In Replacement — Connects directly to the existing coolant or fluid circuit without modification, using the same mounting points and port configuration as the original bottle.
- Broad Heater Compatibility — Fits the E1250S, E1250P, E2200, E3000, HSH380S, HSH380B, and HI1000 series, covering LP/NG, Diesel, and generator-equipped configurations.
- Protects Heating System Integrity — A functioning overflow bottle maintains correct fluid levels during thermal expansion cycles; a cracked or missing bottle can lead to coolant loss and overheating of the heat exchanger.
- Fluid System Safety — Proper containment of expanding coolant prevents pressurized fluid from venting uncontrolled, reducing the risk of burns and fluid-related damage to surrounding components.
The overflow bottle serves as the expansion reservoir for the coolant or fluid circuit in Wacker Neuson ground and air heating equipment. As the fluid heats up and expands during operation, it flows into the overflow bottle and returns to the system as the equipment cools down — keeping fluid levels stable and preventing air from entering the circuit. When the bottle cracks, leaks, or becomes blocked, the system loses its ability to manage thermal expansion properly, which can cause overheating, premature component wear, or heater shutdown.
