The Weil-McLain 383700350 Steam Tankless Heater Kit is designed for installation on compatible boiler assemblies to provide domestic hot water heating. This kit mounts directly into the boiler to utilize system heat for on-demand water warming without requiring a separate standalone storage tank. It serves as an exact-fit replacement or service addition for designated Weil-McLain equipment.
Tankless heater kits operate using an internal heat-exchange coil submerged within the boiler water, rapidly transferring thermal energy to domestic water as it flows through the coil bundle. Installing a functional heater kit maintains steady hot water generation directly tied to the primary steam boiler system.
Key Performance Features:
- On-Demand Water Heating: Captures boiler thermal energy to heat domestic water supplies during system operation.
- Direct Boiler Integration: Installs into designated boiler openings to provide hot water production within the boiler footprint.
- Equipment Matching: Configured for compatibility with Weil-McLain SGO, EG, and EGH series boilers.
Application: Weil-McLain SGO, EG, and EGH series boilers. Please confirm the part number against your existing part or unit, or send your model and serial number to National Boiler Supply to verify before ordering.
