Hydrolevel 48-202 Extended Electro-Well 3/4" NPT with Long Nut for Tankless Coil Boilers

The Hydrolevel 48-202 (EW-202) is an extended electro-well designed specifically for tankless coil boilers, featuring a 3/4 inch NPT connection and an extended nut for easy installation through thicker boiler jackets. This essential component enables HydroStat's low water cut-off (LWCO) function, providing critical safety protection for your boiler system.

Key Features:

• 3/4 inch NPT threaded connection for standard boiler tapping
• Extended design with long nut specifically for tankless coil boiler applications
• Copper immersion tube provides superior conductive surface area
• Replaces common immersion wells for enhanced safety functionality
• Industry standard immersion well attachment method allows HydroStat or virtually any Aquastat to be mounted

When used with Hydrolevel HydroStat series controls (models 3150, 3250-Plus, and others), this electro-well automatically activates the low water cut-off functionality. This ensures safe boiler operation by protecting against dangerously low water levels that could cause damage to the coil or boiler. The extended design makes it ideal for installations where the boiler jacket is thicker or where additional reach is needed to properly position the sensor in the water.

Application: Designed for use with oil and gas fired boilers, particularly tankless coil configurations. Compatible with Hydrolevel HydroStat controls to add critical low water protection without requiring separate control installation.
