The Wacker Neuson Drain Valve is a genuine OEM component designed for HSH350 and E1100 series hydronic surface heaters. As a factory-sourced part, it meets the exact specifications set by Wacker Neuson for proper fluid control and system integrity. Fitment is confirmed for the HSH350 Hydronic Surface Heater and E1100 Ground Heater, including both 50Hz and DG surface heater variants. Keep a verified replacement on hand to avoid costly fluid management issues during cold-weather operations.
Key Features
- Genuine OEM Fluid Control Spec — Manufactured to Wacker Neuson's exact valve sizing and sealing standards, ensuring consistent shutoff and flow control within the hydronic circuit.
- Direct Drop-In Installation — Engineered to connect directly to the existing drain port on compatible HSH350 and E1100 heater systems without modification to fittings or lines.
- Confirmed Fitment — Compatible with the HSH350 Hydronic Surface Heater and E1100 Ground Heater series, including DG and 50Hz surface heater configurations.
- Leak-Free System Drainage — A properly functioning drain valve allows controlled, complete draining of the hydronic fluid circuit; a worn or seized valve can trap fluid, leading to pressure buildup or freeze damage.
- Fluid System Safety — Correct valve operation is critical when servicing or winterizing the heater system; a failed drain valve can prevent safe depressurization of the fluid circuit.
The drain valve in a hydronic surface heater controls the release of heated fluid from the system's internal circuit, allowing operators to safely drain, service, or winterize the unit. In heaters like the HSH350 and E1100, where glycol-based fluid is circulated through ground-contact heating blankets, a functioning drain valve is essential for preventing fluid loss during operation and enabling controlled shutdown. When the valve fails — through cracking, corrosion, or a seized stem — fluid cannot be properly drained, risking residual pressure in the lines and potential freeze damage to the heater assembly.
