Hydrolevel EW202 Extended Electro-Well
The Hydrolevel EW202 (Part Number 48-202) is a heavy-duty extended electro-well engineered specifically for tankless coil boilers. As a veteran-grade immersion well, it features a 3/4" NPT connection and an integrated long nut, providing the necessary clearance for thick boiler jackets and tankless coil plates. When paired with HydroStat controllers, this specialized well is the hardware required to activate the Low Water Cut-Off (LWCO) functionality, ensuring the system can detect a dry-fire condition through metal-to-metal continuity without the need for additional probe drilling.
For professional contractors, the EW202 replaces standard immersion wells to provide dual-functionality: accurate temperature sensing and electronic water level monitoring. The extended design ensures the Hydrostat sensor reaches deep into the water stream, bypassing the "dead zone" often created by gasketed coil flanges. When installing, use a high-quality pipe sealing compound?avoiding PTFE tape to ensure a reliable ground?and verify that there is at least 1/2" clearance between the copper tube and any internal boiler surfaces for optimal LWCO signal integrity.
Key Benefits for the Contractor:
- Automatic LWCO Activation: Instantly enables the low water cut-off logic on HydroStat 3000 and 4000 series controls upon installation.
- Extended Reach: The long nut design and extended shaft are purpose-built for the unique geometry of tankless coil burners.
- NPT Compatibility: Standard 3/4" NPT threads allow for a direct swap with existing manufacturer wells in most cast iron or steel boilers.
- Durable Construction: Built to withstand high-pressure hydronic environments while maintaining electrical conductivity for the sensor probe.
Common Technical Questions:
Can I use heat transfer grease with the EW202?
No. Do not use heat-conducting grease. It can act as an insulator and interfere with the electronic water level sensing required for the LWCO function to operate correctly.
Why is the 'LWCO Active' light not illuminating on my Hydrostat?
The light only activates when the sensor detects the specific Electro-Well hardware. If you are using a standard well, the LWCO function will remain inactive, and only temperature functions will work.
How do I ensure a proper ground for the LWCO probe?
Ensure the boiler tapping is clean and use pipe sealing compound rather than tape. The system relies on the well's physical contact with the boiler chassis to complete the sensing circuit.
