109 Scale Removal System with N42

Product Details

The Zoeller® Model 109 Scale Removal System (SRS 109) is engineered specifically for flushing and scale removal in tankless water heating systems. Over time, mineral buildup within tankless units can reduce efficiency and impair performance. The Model 109 provides a controlled method for circulating approved cleaning solutions through the heat exchanger to remove line buildup as part of routine maintenance. The system arrives fully preassembled, including a 5‑gallon polyethylene tank with sealed lid, stainless steel braided flush hoses, necessary fittings, an internal reusable filter sock, and a submersible pump. This configuration allows the system to be connected directly to tankless water heater service valves without additional assembly. During operation, the Model 109 circulates cleaning solution at an approximate rate of 3 gallons per minute, meeting flushing requirements for tankless water heating systems. The reusable filter sock captures debris removed from the system during the flushing process, supporting cleaner operation and repeatable service calls. Designed for use with approved liquid vinegar solutions or manufacturer‑approved descaling chemicals, the Zoeller Model 109 is a service‑ready solution intended for professional installation and maintenance workflows. Built to Zoeller quality standards and factory tested, the Model 109 provides a dependable tool for tankless water heater scale removal when performed according to equipment manufacturer guidelines.
